Replace Nest/thermostat by smart switch

[Thelion]

For those who don't specifically need the functionality of their Nest or other thermostat, but basically use their thermostat as a on/off switch for the heater based on other temperature readings done by Domoticz:

Take a look at the Shelly 1 smart switch (https://shop.shelly.cloud/shelly-1-wifi ... omation#50). It features separated dry contacts, which can by used to switch your heating on/off, while the Shelly itself is powered by 12v/120v/220v (I currently use 200v, haven't tested the others, so use at your own risk!).

It can be flashed with Tasmota, so it will communicate with Domoticz through MQTT.
