Hello,
Does anyone have any experience with this communication protocol used by some HVAC systems? I'm trying to communicate with my central heating appliance (Remeha boiler) as I don't have a corresponding OpenTherm thermostat.
Despite its name, the protocol isn't "open" and I had a hard time trying to get some deep informations about it. Every diy implementations I've read about is using a commercial OpenTherm gateway (master) and is emulating a thermostat (slave) but, like I've just said, I want to skip that middle-man (gateway).
Thank you in advance for any clue.
