Would love to forgive even one star more

I never came to the embarrassment that the five stars are not enough, but here this is true for me to be the first time.
The thermostat especially in conjunction with the corresponding weather station is great.
The connection to our Vaillant gas water heater was a breeze for me (with me (!!): Power supply via the same terminals as the original recipient, Relayanschl of Netatmo thermostat to phase the receiver circuit and switching input.).

The control over app alone, portal, control unit with eInk display and the PID process would have been great, but for me were
the possibilities to control the system via an open API itself and retrieve the hammer.

So I could easily incredible things realize (about automatic temperature reduction during release (Discovery Using already existing window sensors with me when the radiator thermostats / MAX EQ-3), fully automatic response to additional demands for heating in other rooms, by combining it with the weather station recommendation / report should be stopped airing or meaningful (Using CO2 measurement, indoor / outdoor temperature, humidity), program adjustments to the type holiday treat as Sundays, etc etc
