I have been playing around a bit more with this. Just bought myself a Fibaro STRV to connect to my development toon2.
Results:
- The fibaro STRV has a product bug (also see the fibaro forums) where the STRV doesn't report the internal temperature to the controller (in this case the toon). Only when coupled with the external bluetooth temp. sensor this works. A new firmware 4.5 should be released soon which should enable this but if you read the fibaro forums you can see that the members there are not expecting it to work properly as the interal sensor is to close to the radiator. This means that, if Eneco launches the Fibaro STRV feature they will need to provide those external bluetooth sensors.
- Including the STRV in the toon is easy, just like a plug or a meteradapter.
- due to the bug the STRV isn't showing the temperature on my toon (haven't got the bluetooth sensor)
- changing the temperature setpoint on the STRV using the Toon seems to work, but is has some unnown delay and after a while I do hear the motor of the STRV opening or closing the valve
- each STRV becomes a seperate ZONE in the Toon which you then can give a seperate program and setpoint. So if your room has more than one radiator this becomes a problem as your room is immediatly divides into multiples zones
- making a week schedule is only possible using the toon app (and therefore you need a subscription to Toon). This is probably because programming multiple zones week schedules is hard to do on a screen on the toon (or the Quby programmers are to lazy

)
- the Toon doesn't seem to control the boiler anymore so to have this working you will need a boiler set on 'weersafhankelijk' (weather dependent) which allows the boiler to run its own program (this is very costly though as the boiler is always running)
