Dear Vodo1,
can you share please the pictures after installation according app flow.
What do you mean with “intercom is black”. I guess you mean the LED right?
Hi Vodo1,
thanks for sharing the pictures. It would help to send us also a picture after modification. (inside view). I assume you followed the steps from the App flow.
Let´s try this:
1.Please go back to the inital (original setup, first picture you send). Is the Intercom working now again as before? If yes follow with 2
Now connect only red and black wire. (these are the bus lines).
Red–> a (keep connected white)
Black → b (keep connected blue)
Restart the configuration flow to the end
Check function. Intercom ok? Opener working? If not you can try again with exchanged Red and Black cable on a and b
best regards
Marcel
hei marcel
this is working!
great
and if there furter steps to complete use the opener?
Hi Vodo1,
great to heart that the intercom is back in operation. I assume you went through the configuration flow of the opener with the modified connection (just the bus lines connected).
If so you are set and the opener should operate. The ring tone suppression is missed out with this approach. OK.
best regards
Marcel
Hi @Marcel_Urban,
I have the same issue as described above.
When I tried red & white on a and black & blue on B. The intercom didn’t work. When I switched black and red the intercom worked.
Buuut: I couldn’t finalize the setup of the opener 
In the step where I have to press the door opener on the intercom the waiting wheel keeps turning.
Any other wiring ideas, thoughts? Current wiring.
Dear Flavio Fp67,
I assume you have an Andriod Phone? Currently we are fixing a bug in the setup flow. A new release will come out in the next days.
best regards
Marcel
Hi Marcel, Correct, I’m using a Samsung device. Thanks for your reply. I’ve been in touch with Matija from your developer team. I’ve tried a few different options so far (including borrowing an iphone). Matija also opened up advanced settings remotely. So far still nothing is working. I’ll try with an iphone again over the coming days. When is the update happening exactly?
It would also be awesome to note somewhere that there are issues with Android 14.0 as Android has a 43% Market share vs Iphone of 57% (Statista 2023). Thx, Flavio
