[elmaya]

welcome back.
1. yes.
2 and 3:

the ground of all modules must be connected
the 5v power supply can be common or independent depending on your needs, keep in mind that there will be a loss with long cable lengths.

4. No, you have to use a high level active relay connected with a diode to each of the thermostat outputs.
TA1 relay will be active while some of the thermostat is on

SSR have to be high level trigger.

Wszystko pięknie. Fajnie by było by od tego układu wyrzucić przekaźnik ( stacja np. w pokoju ) a moduł wykonawczy z wemosem i przekaźnikiem przy piecu. Wtedy będzie git

I think I remember that something like this was done with friend @ piomar2.
the relay is in another wemos and is controlled by wifi.
surely when he reads this he leaves the code.

Hello
Maybe a silly question, but why can't I see this device in the application on my phone? I have the wrong version of the application?

Ps. I have already found what I had not noticed in the My SUPLA settings before.

Witam
Może głupie pytanie, ale dlaczego w aplikacji na telefonie nie widzę tego urządzenia? Mam złą wersję aplikacji?

This is "English" variant of Spla forum. Please stick to English language here.

Thanks for the long thread with in-depth explanation, that's really helping me for my build. I'm trying to experiment with smart home technologies before getting myself one of these houses in Alicante, and temperature control systems will be a key element in the house, so it's one of the directions I'm trying to learn the most about.

Hi Elmaya, I have a question if you can do "4 in 1". I need 4 independent thermostatic channels in one device (nodemcuv3) (version without display and physical buttons), I want to control a 4 circuit heating distributor. I have temperature sensors in 4 rooms. I currently have 4 your thermostats installed but this is a "not very elegant" solution I noticed that the close presence of 4 esp breaks communication with them.
