Thanks very much for this! I looked into it a bit last night, and although I’m in way over my head, from what I understand, it should be possible to connect something like this EMS Gateway to the EMS bus.
This device seems like a handy tool for interfacing with the boiler, and it’s compatible...
Thanks for the update. What a shame! I think I'll still give CT200 a try. All our smart home setup is on Home Assistant, and apparently it is possible to make CT200 work with Home Assistant through custom integration. So I might use that until we change this boiler.
Wondering the same thing. I have the same model. Would have never guessed that a boiler would intentionally choose to not expose the 230V terminals. Did you have any luck with this?
