I associated with an outdoor sensor with mixing valves that do not take account of solar gain or use the oven for example, where temperature overruns. The thermostat is placed in the heated floor area, and mutes the boiler and radiators upstairs which was not the case before (I had to leave open the radiators and the boiler was working all winter, the modulis 200 of Elm will not manage that).
The application is great, and the simplified programming 5 questions about our habits.
The official website forum allows us to find answers to our questions and discover the new features (PID, anticipation ...). Two Netatmo weather stations are present in my city, and the thermostat will take into account the external temperature readings to adjust its operation, great!
Congratulations Netatmo, with the offer to pay me back the thermostat to 149!
