Hello Everyone,
It seems to be working on my comelit 2638, at least until some step.
I did wire black one on port 1 and red / orange on port 2 of the bus.
Then the app ask to ring the bell, it works, and then I have the following error when I need to press the open button on my intercom (it basically says I’m out of range for bluetooth which is not the case):
I opened a support ticket as well 231283
Regards,
