There are many TRV heads, some which are truly smart, working out how long it takes to heat a room, so it can start heating the room at the right time to be to temperature when ready to be occupied, and some which only control the temperature to within 3°C of some random set point, where one has to work out what *123456 means in degrees C for the room they are fitted in.
So if we list common features then we can I hope make a list so people can select features they want. A) exercise the valve pin. B) show current temperature. B1) on the device C) show target temperature C1) on the device. D) Able to set temperature on the device. D1) On the app only. E) Window open detection. F) shows under or over travel of TRV pin G) gives a graph of how heating has preformed. H) comes with adaptor kit, or free on application. I) Needs a hub. J) connects to WiFi either direct or with hub. K) Has BlueTooth. L) can be paired with other TRV head. M) can fire the boiler. N) can connect to wall thermostat/sensor.
Energenie = A,B,C1,D1,I,J.
eQ-3 = A,D,D1,F,G,H,K,L.
Kasa = A,B,B1,C,D,E,G,H,I,J,M,N.
Wiser = A,B,B1,C1,F,G,H,I,J,M,N.
Can readers correct any errors, and also add other makes, or include other features, so in the future people can see which head suits them best, or any other comments.
