Like other thermostats, Eve Thermo comes with a standard M30x1.5 connection for your heater’s valve. In addition, the box contains RA, RAV and RAVL adapters for Danfoss heaters. Eve Thermo can easily be connected to over 90 percent of all radiators without requiring any type of adapter.
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 is built around schedules, which are a really simple and effective way to control your Eve accessories. They’re also a breeze to create using the Eve app – and once you’ve done that, they’re stored automatically on your Eve Thermo so your accessory can set about controlling your heating completely autonomously and all independently of your iPhone and an internet connection.
Each room in your home requires a different temperature, and even that temperature should change to suit the time of day: You want it nice and warm in your bathroom early in the morning, followed by your living room a little later on as well as in the evening. Your bedroom should be set to a constant 17 degrees. Plus, you may also want to take into account that you like to doze under the duvet for that bit longer on Sundays and that the kids arrive home earlier on Thursdays. Sounds complicated, right? Well, using schedules means you’ll get everything fine-tuned to suit your routine in a flash.
You can create a custom schedule for each room in the Eve app, plus you can set the comfort and economy temperature for the room in question. You can then configure the various schedules for workdays and the weekend, or individually for each day – or even for all days. Each schedule offers 3 heating phases such as mornings, afternoons, and evenings.
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
Life doesn’t always go exactly according to plan, so to cover all of life’s little eventualities you’re best off controlling your heating using a combination of schedules and location control. At all times, you remain in full control, and your privacy continues to be protected to the highest standards.
To control your heating based on location, you need a home hub (HomePod or Apple TV). This enables HomeKit to determine if everyone has left home without anyone’s location constantly being tracked, recorded, or possibly even shared. Since only the technology baked into iOS is used for this function, it saves your iPhone’s battery and also ensures a profile of your movements cannot be created – not by Eve, by Apple, nor by any other unscrupulous individual who may have gotten hold of your information through a data leak. Your and your family members’ location is always determined based on the particular device set under "Find My" in the Apple ID settings.
Location-based heating is a breeze to set up for Eve Thermo in the Automation area of the Eve app. Go to Rooms, choose Eve Thermo and Automation. There you can also choose whether to suspend schedules when nobody is home. You can also set the temperature you want maintained while your home is vacant.
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.
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.
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.
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.
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.
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.
