Since i don't get any information in my topic about an Opentherm Gateway and a Raspberry pi i just bought the stuff.
I want to control the Nefit Trendline boiler from my Raspberry Pi Home Automation system (Programmed by myself). I want to send the current room temperature, outside temperature and set temperature to the boiler. Programs are controled by the raspberry pi (When what temperature is needed).
Do i need a thermostat to control the boiler via modulating? And if so, what will be the best thermostat for my needs?
Ik hope someone can help me a little more.
I tried connecting a ICY smart thermostat to the opentherm gateway and i could read some data (room temperature, set temperature), but if i want to override the set temperature, nothing happens.
Thank you very much!
