Sabiana Carisma Fly

Hello, I was wondering is someone has this hydronic fancoil
and was able to integrate into HA.
Possibly via esp32 or similar.
O saw they sell their proprietary wifi adapter but very expensive as I have 2 machines.
Any help very much appreciated!

I think you should start with downloading the FC technical docs, like the installation manual to find if there’s an electric schematics that explains whether is it possible to connect “something” to it.

Another option is to disassemble it and kind of reverse engineer the command/controls
