I have a central heating system, driven by a simple thermostat at the entrance of the flat.
There are simple mechanic thermostatic valves in the main rooms.
Two of the room are in the south part of the home and three in the north.
There is a great difference in temperature from sout to north rooms.
When the thermostat cuts heating, the other rooms are not warm. I have to put a high temperature in the thermostat in order to keep the other rooms warm.
But then the temperature in southern rooms is too hisgh and it is difficult to adjust the mechanic thermostat valves in order to get a uniform temperature (and it depends in the difference of temperature from south to north that day).
That is why I am trying to replace of of it for a more versatile system.
But don’t want to install a comercial system that depends on cloud services.
Hestia Pi would be a good start point.
I can program it and measure temperature in thermostat room, in the south.
I plan to install another temperature (and humidity for the same price) sensor in a nothern room and keep heating working if one of the too sensors detects measures a low temperature.
But in order to optimize heating, I will need to control each radiator in each mean room.
To do that I need a thermostatic valve with wifi (or other protocol that I can connect to home net).
Are there any that can be used with openhab and HestiaPi?
Would HestiaPi be able to control that valves.
I suppose that it won’t do it by default, but it seems possible to change the openhab programming in order to get it working.
Would it be better to have a valve with a termostat included or justa a swithing valve and measure the temperature externally through other sensor?
Anybody has tested a similar configuration?
