Hello everyone, I’m a user of diyless gateway to connect Viessman Vitodens 050-W boiler to home assistant.
Boiler does not respond to the gateway connected to it. (timeout) I suspect the problem is I’m unable to change boiler option C7 (d.7) to 14 (OpenTherm) for some reason. It’s stuck on option 2. Have you seen such behaviour ever?
Also, can you confirm for me: which software should I flash on wemos d1 mini to use with HA integration?
Last question: I have seen in viCare app on android - gas consuption data from my boiler. Is this data available within opentherm?
