that’s one of my future projects for my floor heating.
I am lready having the heating valves on the distributor (as on every floor heating). they are 230V in my case.
as far as i am into floor heating, the “common” valves have open / close state only don’t they?
so i am thinking to use pimatic on a raspberry pi with a relay board driven over gpio.
then I am able with the gpio plugin to configure gpio switches to openor close the valves over the relais if a setpoit is reached.
for controlling I still need rf thermostats in every room to control the valves. here my max thermostats could do the job since I already have them and they are affordable if i need more.
but I still need the cube or a cul for them.
some rules and devices in the gui and it should work with no big trouble.
finding the best settings for the room tempereature it’s just a matter of calibration then.
all in all you could use the max heating valves for opening and closing the valves on the distributor but not sure if there is enought space to fit the big actors on each valve then.
gonna try it …
