Heating control via pilot wire

Share your installation
1

Hello la commu Gladys;

Is anyone here managing their electric heating installation via pilot wire via Gladys?
I saw a few posts on the forum about management with thermostat and relay, but it was on the old Gladys, maybe it has evolved in the meantime.

My questions are more for the DIYers :slight_smile:

Any advice on how to do it or the material to consider?

My installation: 1 or 2 radiators per room (toaster type) with a pilot wire per room that goes to the meter.

I thought of several ways to do it:

  • Put a sonoff on each radiator that remains in full position + on (without pilot)
  • Put a multi-output sonoff (or several sonoffs) at the meter on the pilot wires

And as a bonus: Is it possible to replace the thermostat of each radiator with a thermostat per room?
→ Like I put a card with a thermostat that sends the temperature of each room and Gladys controls the activation of the sonoffs? Or is it better to keep the knob on each radiator?

That’s a bit vague, if you have any advice or comments ^^

Happy holidays to everyone
Alexandre

Well, I answered myself, I opted for a sonoff 4chr3 which will allow me to create 4 zones at a reasonable price :slight_smile:

I will do basic ewlink programming and as soon as I have the zigbee thermostats I will flash the sonoff with tasmota for more complete programming :slight_smile:

Oh no, I missed your message!
The heating management tutorial is indeed for this version of Gladys, if that’s the one you’re referring to :wink:
For the temperature modules, among other things, I use these, flashed with Tasmota:

As for the question of whether to keep the « mechanical Â» thermostat, that’s a good one! When you leave your accommodation, what do you take with you? If the Pi dies or the Wi-Fi router is down, no heating?
Is it possible to bypass the thermostats without dismantling everything?

Hello,
Thanks for the link, indeed this module is not expensive at all! Even if I think I will take ready-made sensors directly on my zigbee2mqtt key.

As for the question of whether to keep the « mechanical Â» thermostat, that’s a good one! On the day you leave your home, what do you take with you? On the day the Pi dies or the Wi-Fi router is sick, no heating?

For the mechanical thermostat, it was more like: I set the knob to max and it’s Gladys who regulates the temperature via the sensors. (Plus the radiator probe is a bit crappy sometimes it goes from 19°C to 22°C without touching the settings, the radiators are 15 years old lol)
