All features of Eve Thermo

The fourth generation of Eve Thermo, the award winning smart radiator valve, hit the stores in autumn 2020. Eve Thermo is a breeze to install and setup – and with a bit of fine-tuning, it can unleash all the convenience that connected heating has to offer. Read on for a detailed overview of all the functions Eve Thermo offers. 

Heating via an app, touch controls and Siri 

You can control your heating using the Eve and Home apps or simply ask Siri to make your room warmer, set it at a specific temperature or stop heating. Plus, you also enjoy granular control of your heating in increments of 0.5 °C on the smart radiator valve itself. 

Scheduled heating designed around you

Eve Thermo offers schedules, which you create in the Eve app and that are saved on the accessory itself. This provides you with quick and easy universal and automatic temperature control as it works regardless of whether an iPhone, home hub or active internet connection are available. The Eve app features three preset schedules for many common scenarios – plus you can of course also add your own schedules to suit your routine.

 

You can create up to three high periods per schedule, such as mornings, afternoons and evenings. You can also set separate comfort and economy temperatures. Schedules can behave differently depending on the day of the week, so you can choose different start and end times for the heating phases for weekdays and the weekend. And as soon as you save a heating schedule in the Eve app, you can also use it for your other Eve Thermo accessories. Got a schedule that works great for your kitchen, but not your guest room? Then simply add another one.

 

The “Days Off Calendar” function accesses a calendar chosen by you on your iPhone (such as “Holidays”) and ensures that the weekend schedule is run on days which are public holidays – all without you having to lift a single finger.

 

By the way: Even if a schedule is active, you can still adjust it via the app, Siri or manually on the accessory itself. This setting is then changed with the next scheduled temperature change.

Heating depending on if you’re leaving or arriving at home

You can save energy and minimize your heating costs by having Eve Thermo automatically control your heating based on whether you or a family member is at home or not. If, for instance, the last family member has left home for the day, a lower temperature will be set automatically. Then, as soon as a family member arrives home, Eve Thermo will set your heating to the desired temperature again. This type of automation requires Apple TV or HomePod as a home hub.

 

To heat depending on whether you’re leaving or arriving at home, simply add an automation – or in HomeKit jargon: a location-based rule.

In Eve tap Automation > Rules > Add Rule. A short explanation will be displayed, then tap Next. 

Eve will display all available triggers, which can be based on the time, the sensor measurement or someone’s location.

For this straightforward example, select the Location > Leaving [home] and then the Last person leaves [home] option. Tap Add, then Next. You don’t need to set any other time or value conditions here, so tap Next. 

– You don’t need to set any other time or value conditions here, so tap Next. Eve will now offer you the option to select an existing scene that will set the away temperature on the desired radiators.

If none are available, create the scene by adding a new one. Tap Add Actions and select Types > Target Temperature. Activate the Eve Thermo accessory you want to control, set a temperature and tap Add.

 

Tap Next, name your scene – such as “Away Mode” – and select an icon. Following that, tap Done and then Next. Give your rule a memorable name, something like “Last One Leaves”, and tap Done.

 

If you also want to prevent a scheduled temperature change in the schedule from changing this value even if you are away, tap Types > Schedule again and disable the schedules for the radiators in question.

 

A second automation will ensure that the heating kicks in again when someone arrives home. 

- So start with Automation > Rules > Add Rule and in the Location section in Add Trigger tap Arriving at [home] followed by the First person arrives [home]. 

- Other conditions aren’t required here, so simply tap Next until you get to the Scenes selector where you should tap Add Scene followed by Add Actions. 

- In the same way as the away scene, tap Types > Target Temperature, but this time set the comfort temperature and then Add.

- If you previously disabled your schedules when leaving the home, add an extra action to re-enable them.

- Tap Next, name your scene (such as “Cozy at Home”) and choose an icon – that’s it. Once again, you complete the process by naming the rule (in the example, the automation is called “Back Home”). Once you’ve tapped Done, your location-based heating system is good to go.

 

By the way, using this Eve Thermo configuration for heating based on whether you’re at home or away is controlled entirely by HomeKit. This means that your location will be checked using only the native system-level functions of your iPhone. Absolutely nobody – neither Apple nor Eve – can piece together a complete profile of your movements. Furthermore, nobody will know if you’re at home or not, apart from your Apple devices themselves. That’s great for your privacy, and your battery too!

Eve Thermo in the Eve app

You can dive into Eve Thermo’s details view either by tapping the Rooms view in the Eve app or by long-pressing (or using 3D touch, if your device supports it) the particular accessory’s icon in the At a Glance view. Besides the accessory settings, the details view is the main dialog for controlling your smart radiator valve. It is divided into the General section, Target Temperature, Mode and Schedule.

 

General:
Tapping the small arrow on the right opens the advanced view, which includes a battery status indicator, an accessory settings icon and the identify button, which when tapped will display a “Hi” on the Eve Thermo in question. The latter is handy if you own several smart radiator valves and you want to make sure you’re in front of the right accessory when changing the batteries.  

Target Temperature: 
The central field of the detail view shows the current target temperature, which is the room temperature you want Eve Thermo to reach. Use the up/down buttons to adjust this value in 0.5 °C increments. 

 

The measured temperature currently measured by the accessory can be seen on the left above the graph in the form of a thermometer/heater icon. HomeKit treats the sensor in question just like a stand-alone temperature sensor or that of a wall-mounted thermostat or air conditioner. Siri and the display in the Home and Eve apps display this value as measured. Any configured temperature offset (see below) is not included in the calculation by the accessory or app. Discrepancies between the actual and target temperature during heating are normal, as factors such as the sensor being located on the radiator instead of in the center of the room (and also the configured temperature offset), the 10-minute measurement interval and the smart radiator valve’s control algorithm play a role here. If, for instance, you want to heat up a room again that has cooled down, the temperature measured at the radiator’s fully-opened valve will initially be significantly higher than the target and actual room temperature – and don’t forget that the same temperature will be displayed for 10 minutes until it’s refreshed.

 

A yellow radiator icon will also be displayed above the graph when Eve Thermo is currently heating. You will see a stopwatch next to the target temperature button when a schedule is active (any manual setting will only last until this particular schedule is due to start again).

 

The graph will show a timeline with the progressions for the measured  (gray) and target temperatures (blue). Daily highs and lows as well as the last measured temperature will be marked with dots. Tapping the small info icon will allow you to view the graph by hour, week or month. Additionally, you can stop the target temperature from being displayed in the graph, deactivate Graph Line Smoothing and access temperature readings in the list view.  

Mode: 
The Mode section lets you disable Eve Thermo’s heating function. The mode returns to On if you enter anything via the accessory’s touch controls or use Siri, automations or the Home app to trigger changes. However, please note that even when in the Off mode, valve descaling cycles, and a certain amount of noise in connection with that, will continue. The temperature will also continue to be measured. If radiator valves are grouped, switching off one accessory will not affect the others.

 

Schedule: 
The current schedule stored on the accessory is displayed in the bottom-most section. It can be deactivated permanently via the On/Off button – and will stay deactivated even after the next heating phase is reached. Tapping the gear icon will take you to the schedule section with the schedules contained in the Eve app and those added by you. You’ll find an info icon next to the latter, which you can tap to bring up the schedule editor.

Settings

You’ll find all the key functions, some of which you’ll have already seen during the initial setup, in the settings for Eve Thermo (Eve > Settings > [Room] > [Eve Thermo]). Starting from the top.

 

Room: This is where you’ll find the room you assigned your Eve Thermo to during installation. You can change it at any time. 

 

Name: This is the Siri name you set during the initial setup. Although entirely optional, a meaningful Siri name such as “Living Room Heating” can make controlling Eve Thermo with your voice a lot easier. 

Installation: Here you can see if Eve Thermo has been installed correctly (OK). If you want to use your accessory on a different radiator in your home, but want to keep the data, tap Installation >  Remove. You can now remove Eve Thermo and calibrate it at its new location. If you ended up installing the display upside down, you can change its orientation here.

 

Temperature Offset: As Eve Thermo connects right next to the radiator, which is often located under a windowsill, the values measured may deviate from the actual temperature in the center of the room. To compensate, you can configure a temperature offset which Eve Thermo factors in when controlling the valve. If the room temperature is lower than the measured temperature shown in the app, set the temperature offset to a negative value. For example, if your lounge is 20 °C, but Eve Thermo reports 21.5 °C, set the temperature offset to -1.5 °C. Over time, you’ll need to work towards finding the ideal temperature offset that works for the particular room.

 

Window Detection: If you use Eve Door & Window on a window in the room where you’re also using Eve Thermo, Eve can automatically stop heating if the window is opened for ventilation purposes. It then resumes heating once the window is shut. This type of automation requires Apple TV or a HomePod as a home hub.
Window Detection is smart: If you forget to shut the window, heating resumes automatically after 30 minutes to prevent the building from cooling down. However, you can adjust this value to suit. 

Eve Thermo detects rapid drops in temperature even without a wireless contact sensor, however it’s less precise than when used in conjunction with Eve Door & Window. In this mode Eve Thermo continues to heat again after 10 minutes. 

 

Vacation Mode: About to take a long vacation? To avoid having to adjust each radiator individually or add a different schedule, you can simply activate Vacation Mode. It’ll suspend your schedules, hold the energy-saving temperature you’ve set and prevent your home from freezing up. Here you can set whether the Eve Thermo in question should be part of the vacation scene and the temperature you want maintained. Once you’re back from vacation, simply activate the Back from Vacation scene and everything will return to normal. .

Valve Protection: Eve Thermo will open the valve fully every three weeks to prevent scale buildup. If you trigger this function manually, Eve Thermo will remember when you did so and resume automatic valve protection three weeks from that time of the day. 

 

Temperature Unit: Choose between Celsius and Fahrenheit. 

 

Child Lock: To prevent unwanted temperature adjustments, activate Child Lock to disable the touch controls of Eve Thermo. 

 

ID: Tapping ID will display Hi on the Eve Thermo in question. It’s really handy if you want to identify a particular Eve Thermo accessory.

 

Remove Accessory: This command lets you remove a particular Eve Thermo accessory from your HomeKit configuration. You may want to do this if you intend to relocate your accessory to a different home.

 

Assigned to (optional): If you have assigned Eve Thermo to an Eve Extend range extender, it will also appear here in the settings. 

No bridge or starter set required.

Eve Thermo works right out of the box, eliminating the need for additional accessories. Schedules are stored directly on the accessory itself, so they’re always executed without the involvement of any other devices. 

 

For automations (such as heating based on if you’re at home or away, or window detection in conjunction with Eve Door & Window), you’ll need Apple TV or a HomePod as a home hub.

 

To expand your reach to Eve Thermo in the furthest corners of your home, especially if you have a large apartment or house, you can use an Eve Extend Eve Extend Bluetooth Range Extender. 

 

100 % Privacy

Eve accessories are designed to safeguard your personal data. All data is fully encrypted and only transferred directly between the Eve accessory and your iPhone, iPad or home hub. Strong encryption verification during each connection attempt makes sure that only you hold the key to your home.

Hi - I want to have a boost-function like other vendors have. When I go to bathroom having a shower I want the Eve Thermo to start heating on maximum level for 2 min. is there a way to make this happen with an HomeKit automation, rule maybe in combination with an Philips Hue Smart Button? Thanks in advance

hello, I have one question: I have a Gas condensing wall hung boiler at home, as I found out eve thermo is not meant for that, but I only noticed it when I already bought it. Now I use thermo in the bedroom, because the boiler does not work all day, but only in the evening and in the morning I open the valve every time and when it stops heating, I close the valve. I wonder if this is safe for the radiator? If I leave the valve open all the time, I hear the valve turn every now and then, and that's annoying in the evening when you sleep, can that be turned off? What can you recommend me? thanks
Reply
Nov 26, 2020
Hello Alex! Eve Thermo works when hot water is always available. So while the boiler is off, the valve will work all the time trying to adjust the selected target temperature. What you could do to avoid ist use the function Schedule in the app Eve. Selecet the Comfort temperature for the time the boiler is on and 10 degrees while off. It will shut the valve then.

Hi, I am considering buying these. A few questions first:

What are their batterylifes?
Is it possible to adjust the amount of time the valves turn off with an open window to more than 10 minutes ( we dont have the window open/close sensor)
Will you update the software within the valve when new software is available, or will it at one point be obsolete?

Best regards
Reply
Nov 25, 2020
Hello Anders! The batteries (2*AA) will last about a year/heating season. You can only adjust the window detection if you are using Eve Thermo with an Eve Door & Window in the same room. With only Eve Thermo the 10 minute Off is fix once Eve Thermo detects a decline of 4 degrees or more per minute. Best regards, Volker

Are these suitable to change the zone tempest or for under floor heating? All five thermostat valves are situated next to each other in a cupboard. I would need something like eve room in each room (two heating zones per room) to control the room temperature, I imagine.

Hi,

ich nutze zur Zeit Eve Door & Window Sensor mit den Thermostat. Ich würde nun gerne eine Regel einrichten das sobald das Fenster für Zeit X (als Beispiel 25 min) offen ist, eine automatisch Nachricht auf mein Handy geht (z.B. falls man vergessen hat das Fenster zu schließen) oder eine andere Aktion auslösbar wäre. Wird es solche eine Option geben? Momentan geht ja nur das sofort eine Nachricht geschickt wird sobald der Sensor ausgelöst wird (Offen oder Geschlossen).

Hallo,
ich finde nirgends Informationen zu der Reichweite der Bluetooth Low Energy des Eve Thermo, wobei das eine entscheidende Information wäre.
Meine Wohnung hat gut 100 qm, 3 Räume, jeder Raum mit separatem Zugang vom Flur. Die Apple Steuerzentrale (Apple TV, HomePod) wäre in einem der 3 Räume.
Danke & Gruß, Roland
Reply
Nov 11, 2020
Hallo Roland!
Die Reichweite liegt bei etwa 8-10 Metern ohne störende Wände. Zumindest die Eve Thermo in der Nähe der Steuerzentralen sollten immer und von überall erreichbar sein.
Falls es sich um neue Eve Thermo (2020) handelt, sollte es in absehbarer Zeit aber auch eine Lösung über Thread geben (https://www.evehome.com/de/blog/homekit-ueber-thread), die dann aber einen HomePod mini im Zuhause voraus setzt. Viele Grüße, Volker

Hinweis bzgl. Fenster-Erkennung mit Eve Door & Window: Automatisches Ausschalten und Wiedereinschalten der Heizung geht, wie im Artikel oben beschrieben, nur mit einer Steuerzentrale.

Man darf sich dabei nicht von der Eve App verwirren lassen. Dort steht in den Geräteeinstellungen unter „Fenster-Erkennung“ nämlich nicht, dass eine Steuerzentrale dafür notwendig ist. Dies suggeriert, dass die Geräte selbstständig miteinander kommunizieren können. Es geht aber nicht richtig 😕 Ohne Steuerzentrale geht die Heizung nicht wieder an, wenn das Fenster geschlossen wird.
Ans Entwicklungsteam: Vielleicht lässt sich der Hinweis in der App ergänzen, damit es dort noch deutlicher erläutert wird?

Hallo Pierre!
Ich reiche die Bitte gern weiter. Die Fenstererkennung ist in der Tat eine Automation/REgel, eine Steuerzentrale ais also voraus gesetzt. Viele Grüße, Volker

Hallo, zum Thema Fenstererkennung hätte ich auch eine Frage...kann ich irgendwie einstellen, dass die Heizung nach dem Öffnen zB der Haustür erst nach x Minuten pausiert? Die Haustür wird ja schon mal häufiger nur kurz geöffnet, da muss dass Ventil des Thermo nicht sofort schließen, sondern nur, wenn die Tür länger aufbleibt (Batterien!).

Hi,

gerne würde ich Temperatur-Empfehlungen/Ratschläge für eine kleine Wohnung (65qm) und den dazugehörigen Räumen

Wohnzimmer
Schlafzimmer
Badezimmer

erhalten, damit die Heizkörper nicht sinnlos bollern wie bekloppt und massig Energie verbrauchen. Sicher ist das immer ein individuelle Angelegenheit, da jeder ein subjektives Wärme-Empfinden hat. Trotzdem könnte es mir als Orientierung helfen. Schließlich macht es wenig Sinn die Heizungen bspw. zu tief runterzufahren, während sie dann mehr Energie als nötig aufwenden, um die gewünschte Soll-Temperatur zu erreichen.

Daher die Zusatzfrage: Spart es Energie, das Thermostat in der Nacht deutlich runterzufahren und tagsüber (zu den gewünschten Zeiten) hochzufahren? Oder ist eher eine konstante Regelung sinnvoll, bei der max. 2-3 Grad Unterscheid zwischen Tag und Nacht vorliegen? Ich höre und lese dazu viele Meinungen. Viele sagen, dass eine große Temperaturdifferenz sowohl massiv Energie kostet und zudem Schimmel fördern kann. Wenn bspw. mein Wohnzimmer von 23 tagsüber auf 16 in der Nacht um ganze 7 Grad schwankt, entsteht Kondensationsfeuchtigkeit. Vor allem hinter Möbeln an den Wänden. Und dadurch entsteht eben Schimmel. Andererseits ist ja genau dieses Auf/Ab das Sinnvolle an den Geräten, die Temperatur dann und dort runterzufahren, wo sie zu dem Zeitpunkt nicht benötigt wird.

Vielen Dank für den Rat

Hallo Frank!
Ich würde grundsätzlich mit der Funktion Heizplan arbeiten in Eve. Das klappt wunderbar. Hier ist eine Wunschtemparatur zu wählen und eine Eco-Temperatur, dazu die Zeiten, wann welche genutzt wird. Ein Beispiel wäre das Badezimmer von 7:00-8:00 Uhr auf 23 Grad, dann am Tag auf 16-18 am Abend wieder warm.
Grundsätzlich und das gilt auch für manuelles heizen: Eine Heizung auszuschalten, mach keinen Sinn. Kühlt die Wohnung dann komplett aus, wird mehr Energie benötigt, will man es warm haben.
Die genauen Werte sind sehr viel auch persönliches Empfinden. Bei mir ist es auf 22 Grad gestellt, bin ich in dem Raum und auf 18, bin ich nicht da.
Ich hoffe, das hilft Dir weiter, viele Grüße, Volker

Oct 28, 2020
Hi Volker,

danke für die Rückmeldung. Die Funktion Heizplan in Eve ist mir selbstverständlich bekannt und wird auch entsprechend für die jeweiligen Räume individuell genutzt. Meine Frage zielte mehr darauf ab

welche Unterschiede zwischen Wunschtemparatur und Eco-Temperatur sind zu empfehlen? Sprich dürfen die Gaps auch mal 4,5,6 Grad betragen oder ist das eher kontraproduktiv, weil die Heizung viel mehr von Eco zu Wunsch an Energie aufbringen muss, als man durch das Absenken einspart? Ich teste bspw. gerade das Schlafzimmer, bei ich morgens für 1 1/2 Std. alles mit etwas Vorlauf vor dem tatsächlichen Aufstehen auf 22 Grad fahren lasse, während ansonsten alles tagsüber als auch über Nacht auf 16 Grad runterfährt. Too much? Besser so etwas wie 21 und 18 Grad, sprich 3 anstelle 6 Grad Unterschied?

Grüße, Frank

Hallo Frank!
Ich heize zum Beispiel das Schlafzimmer von 10:00 bis 20:00 auf 21 Grad, dann in der Nacht ist die Eco-Temperatur auf 16 Grad gesetzt. Das geht prima. Der Raum wird auch im Winter nicht kälter, als 18 Grad - Metwohnung mit anderen Parteien unter mir. So verhindere ich Heizen Nachts.
In anderen Räumen is es individuell ähnlich, der Unterschied zwischen Komfort- und Eco-Temperatur ist bei mir zwischen 3 und 4 Grad - seit Jahren. Ich hoffe, das hilft Dir, Volker

Hi
I have my own boiler, that's regulated through one central wallmounted roomthermostat. How do I make Eve Thermo cooperate with that, as regardless of whether the radiator valves are open or close, the central thermostat will make the boiler boil or cool.

Hello Richard!
Eve Thermo does not work with installations with a central room thermostat. Eve Thermos only works when hot water is available always. Best regards, have a great Sunday, Volker
Reply
Oct 25, 2020
Hi, if I may make a suggestion: set the central room controller to weather dependant control instead of room temperature control. You could program the central room controller to switch off the boiler completely during periods where eve thermos are all off. This way the pump is not running whole night. This way of controlling requires (smart) TRV’s trough the whole system or the rooms overheat.

Also note for weather dependant control the system requires something like an open shunt or bypass circuit.

It would be nice to have more flexibility by selecting multiple temeratures for an automation. E.g. During Night 18C, from 6:00-9:00 then 24C - from 9:00 - 19:00 them 20C - from 19:00-23:00 again 24C...
It would be cool if you could provide such an ease of setting multiple Temeratures ina future release.

Hi,

I installed 7 of these and it is real convenient. Also I think the ETRV’s from Eve look good compared to the competition. Happy with this purchase.

One small issue I have. The temperature values (both target and actual) do not refresh in the Home App, i have to open the Eve App and do a pull and refresh. Other people in the house get confused about the old values it shows. I do not experience this with other devices like eve door and window which push new values to the eco system.
What do I need to do to fix this?

Best Regards,
Henkjan

Oct 19, 2020
Hello Henkjan!
Eve, and all other 3rd party HomeKit-apps (Home.app is the only privileged one) are only clients using the HomeKit framework and its (public) capabilities. So a change in temperature or target temperature should be visible and updated in all HomeKit enabled apps at least upon opening the app where the sensors are all queried.
I don't know why Home does not show the actual data, sorry. Best regards, Volker

Oct 20, 2020
Hi Volker,

I do not think it is App related. When i open a door a new value appears in the Home App that was sent by Eve door and window. The same goes for hue bulbs, the bridge pushes new set values and they are updated in Eve and in Home. I would like Eve thermo to do the same. I see this as a firmware issue in Eve thermo. And it brings a lot of confusion in my family...

Hello Henkjan!
You're not a pain.
It is the app Home from Apple, I don't know why it does not update the values from Eve Thermo. As you can see Eve does and both apps rely on the same HomeKit framework.

Oct 22, 2020
Hi Volker,

That is true. But it is also remarkable that eve door and window triggers an update in both Eve and Home App when the open/closed status changes. No need to do a refresh.
Did the team check why this is not happening for changes to eve thermo?

Best regards

Hi Henkjan,

interesting to read your issue. I've also bought a few Eve thermostats and 3 Door & Windows switches. Same issue you described. The Apple Home app often shows previous values, I've to open the EVE app which updates the states and reopen the Apple Home app. Then the values and states are correct. It affects the "on/off" state and temperature of the thermostats as well as the states "open/closed" of the switches. I can exclude problems range problems of the transmitters, Apple TV 4k is close to the devices.

Nov 11, 2020
Hi,

Exactly my problem indeed.
At first I also suspected range but as soon as I start Eve the values refresh without any problems. It just seems some devices push updates and some do not. Or they do and stuff does not go trough the homekit sdk for some reason.
I really hope this will be fixed.

Hallo liebes EVE-Team, ich habe in meinem Haus 15 Thermostate verbaut. Alles funktioniert einwandfrei und lässt sich wirklich sehr einfach installieren. Insbesondere die Verbindung mit den EVE Door & Window sind eine tolle Ergänzung. Ich habe wenige Smart-Geräte im Haus, die so einfach und vor allem so zuverlässig funktionieren. Gratulation! Nun habe ich aber dennoch ein Problem mit einem Thermostat (2020-Version). Hier scheint der Motor nicht sauber zu funktionieren. Beim Einlegen der Batterien, springt der Motor nur kurz an und stoppt sofort wieder. Bei allen anderen Geräten läuft der Motor einmal komplett durch. Trotzdem versuchte ich das Thermostat zu installieren, aber auch hier bricht er bei der Kalibrierung ab und liefert eine Fehlermeldung (ERR). Auch ein mehrfacher Reset, sowie das Entfernen der Batterien hat leider nicht zum Erfolg geführt. Gibt es eine Möglichkeit den Motor selbständig zu justieren oder muss das Gerät ausgetauscht werden? Vielen Dank für eine schnelle Rückmeldung. /Sebastian

Hallo Sebastian!
Du hast bereits alles versucht, das gerät ist wohl leider defekt und muss beim Händler getauscht werden. Sollte natürlich nicht passieren, kommt aber leider mal vor.
Viele Grüße,
Volker

Hallo,

ich habe einen eve Room und ein eve Thermo im gleichen Raum.
Dadurch wird in der Apple Home app immer der Mittelwert beider Thermostate angezeigt, welcher nicht die Korrekte Temperatur darstellt, weil der Offsets nicht abgezogen wird. Gibt es eine Möglichkeit die Temperatur anzuzeigen mit Abzug des Offsets oder das nur die Temperatur des eve Room angezeigt wird?

Vielen Dank

Hallo Kay!
Die Einstellung des Offset wird in die am Heizkörper gemessenen Temperatur nicht eingerechnet, sie ist zu vernachlässigen, da stark beeinflusst von baulichen Vorgaben des Heizkörpers.
Viele Grüße, Volker

Hi Volker,

ich habe eine Frage zu den Zeitplänen: wenn ich die Funktion mit dem Freie-Tage-Kalender nutzen möchte, wie werden diese im Kalender identifiziert? Einfach jeder Tag mit einem ganztägigen Ereignis?
Gerne würde ich das Feature so nutzen, dass ich immer die freien Tage für die nächste Woche eintrage (bzw Home Office Tage). Wie oft wird der Zeitplan auf dem Eve Thermo aktualisiert oder muss ich das manuell triggers?

Danke und viele Grüße

Hallo Herr Müller! In der App Eve wählen Sie den Kalender in Einstellungen, der Ihre freien Tage beinhaltet. Ist hier ein ganztägiges Ereignis eingetragen, wird der Wochenende-Heizplan genutzt - das geht automatisch, ist der ganztägige Termin spätestens am Tag vor dem Ereignis eingetragen. Viele Grüße, Volker

Hallo Volker

Die gleiche Frage nochmal 🙂

Wenn ich einen Kalender bereits als „Freie Tage“ im Zeitplan aller Eve Thermo‘s eingerichtet habe, und danach einen weiteren Ganztagsevent in den Kalender nachschiebe, z.B. Home Office Übermorgen, wie stelle ich dann sicher, dass alle Eve Thermo‘s diese Änderung mitbekommen?

Dies hat bei mir nicht ohne Weiteres geklappt. Am Home Office Tag war erstmal kalt... 🧐 Wie stelle ich sicher, dass es das nächste Mal warm ist? Reicht ein Öffnen der Eve App um die Eve Thermo’s in Reichweite zu informieren? Oder muss ich alle Zeitpläne editieren, und wenn ja wie mache ich das am effizientesten?

Hinweis: Keine HomeKit Steuerzentrale bei mir, nur ein iPhone und mehrere Eve Thermo.

Viele Grüße
Pierre

Hallo Pierre! Auch hier sollte eine Steuerzentrale vorhanden sein, damit das ausgelöst wird. Das Öffnen der App in der Nähe des Eve Thermo mag helfen, das ist aber nicht der Sinn der Sache. Viele Grüße, Volker

Hi!

Got my first Thermo valve and have a question. The valve seems to close very slowly as can be seen in the valve graph, which didn’t get a mention in this article. If I set my target temperature to 20 degrees the valve doesn’t fully close until it measures 23 degrees, then the residual heat in the radiator continues to raise the temperature by a further 1-1.5 degrees. Is there an algorithm that learns how long it takes a room to get to a set target temperature and therefore begin closing the valve sooner? or do I need to bear it in mind and set a lower target temperature to begin with?

Thanks I’m advance!

Hello Andy!
Here is a How to set up Eve Thermo including the Offset

Important note: The temperature displayed below Target Temperature in Eve is measured by Eve Thermo way too close to the heater, please ignore it. Once an Offset is set, it will not be integrated here.

To set up Eve Thermo open the app Eve and goto
Settings > Accessories > Eve Thermo
Set Temperature Offset to 0 degrees.

Then in Eve goto Rooms > Eve Thermo and open Eve Thermo.
Set Target Temperature to 23 degrees for example and let it heat for 2-3 hours.
Then measure the temperature in the middle of the room with a thermometer, Eve Degree or Eve Room.
If it reads for example 20,5 degrees, goto
Settings > Accessories > Eve Thermo and set the Temperature Offset to -2,5 degrees.

You may have to adjust this over the next days a bit.
As stated before, the Temperature Offset is not taken into account in the temperature shown below Target Temperature.

Hope this helps, have a great Sunday! Volker

Hi!
1) Regarding "The fourth generation of Eve Thermo, the award winning smart radiator valve, hit the stores in autumn 2020"
Since you're speaking of the 4th generation - is there a way to identify the 4th generation (e.g. with a model number)? That's always a bit of a difficulty between generations.

2) Also for clarification does "in autumn" mean now or when is it? What sellers are carrying the new 4th generation model in Germany?

3) Also is there a list of the differences to the 2019 model? It clearly requires a higher iOS version but outside that I couldn't find any information.

Best regards!

Hello Steven!
You'll find out when checking the first two characters of the serial number. on the device or on the bottom of the box:
CM = 2020
LV = 2019
BM = 2017
AM = 2015
We already sell it in our web store, so do our retail partners. But make sure to get the new one because they may still sell the model 2019 as well. Requirements are the same as for model 2017 and 2019. Just a hint. I would always go for the latest model. Best regards, Volker

Hi Volker,

What’s the difference between models? I have two 2017 models and I’d like to buy two more. What’s the advantages when I’ll get the newest 2020 model?
I couldn’t find any information on the upgrades.

Thanks

Hello Nereus!
The motor in Eve Thermo (2019) and (2020) is more quiet. I would alway go for the latest model, just to be on the safe side.

Hello Volker,

I can’t find any detailed tech specs for the eve thermo 2020. Is the Bluetooth Version raised to 5.0 or is it still lower? If the new version has Bluetooth 5.0 I would change some thermos due to better connectivity.

Many thanks and kind regards,

Christian

Hello Christian! Eve Thermo (2020) does not use Bluetooth 5, it uses the same version the older models use. Best regards, Volker

Hi

I'm interested in the Eve thermo, I have two questions about the possibilities of the products.
I have an underfloor heating in the living room and kitchen (one big room) with 3 heating loops.
1. Is it possible to have 3 valves controlling the heating in the same room?
2. Is it possible to use Eve room as a thermostat to control the valves?

Best regards,
Ragnar

Hello Ragnar!
Eve Thermo does not support underfloor heating and relies on setting the Offset in the app Eve what makes no sense on underfloor heatings.
Using an Eve Room (2018) makes no sense as well, because the Offset would have to be set anyway.
Sorry, but Eve Thermo just does not meet your heating system.

Volker, what does “Off” mode for Thermo mean: radiator valve closed or open?
I have a centralized heating in house and during summer it is turned off, so actually better to keep valves open.
If “Off” mode is closed, does Thermo still runs periodic open/close cycles?
Reply
Jul 22, 2020
Hi Mark!
Setting the mode to Off closes the valve. I usually do this in spring when no more heating is needed. Along with setting Schedule to Off and disable the Window Detection. Turning all On again in Autumn, when it's getting colder.
The cycles for valve protection are done.

Hello!
Can the Thermos be used with Eve Window only or any HomeKit compatible device will do, for example Aqara Windows sensor?
Reply
Jul 17, 2020
Hello Mark!
If you talk about the function/rule/automation Window Detection this is only available for Eve Thermo users with Ev accessories like Eve Door & Window and Eve Window Guard.
You may though create a rule in Eve or Home that does pretty much the same when using a HomeKit enabled contact sensor from other brands.

Thank you for the reply!
Down the same road: I assume that only proprietary temperature sensor can be used to Auto-calibrate room temperature, but the same can be achieved with any sensor using Eve scenarios?

Hello Mark!
No external sensor needed at all. Just adjust the Offset and you are good.

I was thinking how the offset works and have a doubt that it is overly correct.
For example, I have radiator in a niche covered by decorative screen. In my case working/open radiator would translate in a pretty large temp offset, while closed radiator can in a while has zero offset.
So I am considering feeding Thermo data from external sensor.

Jul 23, 2020
Hello Mark!
Using an external trigger does not work well at all.
I would try the following first. Set the Offset to 0 degrees then the Eve Thermo to 23 degrees. Wait for 2-3 hours and measure the temperature in the middle of the room with a thermometer. Would ist be 19,5 degrees, set the offset to -3,5 degrees. I would give it a try. Best regards, volker

Hello, I'm interested in your system. However, having a gas boiler, how is it possible to control its operation without any smart thermostat connected to the boiler. This way, I can only control the radiator valve, but I cannot make the boiler turn on automatically.

Best regards

Hello Rui!
For Eve Thermo hot water for heating has to be available at all time. It does not at all control the boiler at all. The boiler har to be on all the time in the heating period.

Hello, we have cooling through the floor heating. Can I set the valves in a cooling mode to be fully open in the summer? Or can I do a workaround and set them on a value above 30°C so that the would be open all Summer?

Hello Simon!
Sorry, but this won't work at all. Eve Thermo relies on a heater and always hot water available.

Very happy with my 6 eve thermos installed. Combined with 2 Apple TV’s and an eve extend this works perfectly.
Question: in summer is it better to switch the thermos to ‘mode off’? Or keep them on ‘mode on’ and set the thermos to a low temperature? What’s the advantage of turning them off, energy saving for the batteries?

Hello Richard!
I set all my Eve Thermos in summer for Mode and Schedule to Off and make sure, there is no automation running that might turn the Eve Thermos on like "When arriving turn on lights and Eve Thermos".
The frost protection at 10 degrees is always active, can't even be deactivated.
Best regards, stay safe, Volker

Apr 25, 2020
Thanks Volker for the quick reply.
But I could also set the Thermos to 15 degrees celsius and with higher temperatures in my house during summer the valves would also stay closed. Is there a specific reason why you turn them off in summer?
Reply
Apr 26, 2020
Hello Richard!
Of cause you can. The valves would not open unless the temperature in the room falls below 15 degrees. I turned it off during summer cause the boiler is on always and the temperature does never fall below 20 degrees in summer. It not a difference from the time when we had only manual thermostats. In summer I set all to just do the frost protection. This is even active when turning off Eve Thermo, the frost protection turns on once temperature falls below 10 degrees. This can't be turned off, it is one of the basic functions of Eve Thermo, build in.
