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.
