Ritto 17857 / .0 Opener Ring to Open


The Version .0 is not supported - I’ve only checked 17857 which is supported.

While the Initial process, the app recognises the ring and opens the door. After a few hours the Nuki opener does not recognises the “Ring”.

Does anybody has any hint? It is a BUS System.

I tried the minimal installation, only the black and red wire and the advanced setup , which can silence the bell.

Thanks for your support.

Is there the possibility that BUS + and BUS - are switched?
