Spirit thermostat from Eurotronic / Aeotec supports manual mode (% control). Unfortunatelly beacuse of Thermostat class it’s not possible from Vera UI. On the Internet you can find that there is no option to control it like that! But there correct answer is YES - you CAN!!
If you change to manual mode you can easily control % of your heating valve and you can use for it different temperature sensor (not build into thermostat).
Below on youtube I showed how it works. I created virtual dimmer and linked it with Spirit Thermostat just to control it.
In description I’ve put lua commands to turn on manual mode and example of code to send % position.
