Thermostatic device

Post by ewok002 »

Hello
I would like to control each radiator of my home at distance
about 8 radiator

Some constraint : a interface WAF compatible with temperature ajustable and a night/day button.
after some search I have found some possibilities 4 (or 5) :
1 - head Danfoss living connect + ST814 z-wave + Rasberry with module razberry + relay on the heater + personal box with bouton/diode day/night
the + : danfoss head are pretty ,local control is possible.
the - : thiese head have a PID and the change of threshold is not take into account immediately

2 - head Stella Z + ST814 z-wave + Rasberry with module razberry + relay on the heater + personal box with bouton/diode day/night
the + : head Stella Z seems to use all Z-wave possibility, instantanous time response.
the - : bad quality of head , no local action possible

3 - Pack evohome Honeywell + head THR092 + Rasberry with module razberry + relay on heater
the + : interface WAF ok
the - : same frequency but not Z-wave. Is it connectable to a raspberry

4 - Pack eQ3 Thermostat on wall and head + Rasberry with module razberry + relay on heater
the + : interface WAF correct. Not expensive
the - : same frequency but not Z-wave. Is it connectable to a raspberry

5 - electrical Honeywell actuator mt4 230s + Raspberry with module razberry + relay on heater + personal box with LCD/bouton/diode day / night
the + : everything is manage from the raspberry and it is not expensive
the - : many wire to install.... no local radiator control.

that is all ;-)

option 5 is only if the 4 first are not possible.
If you can correct the + / - and add other

Thanks
