Connecting Tesla 4FP 211 02.201 to Nuki Opener

[Robin111 (Robin Nguyen)]

Hello,
I recently bought 3 Nuki Openers for apartment building.
2 of them are connected and work properly but i can not figure out how to connect 3rd one to telephone Tesla 4FP 211 02.201 (it have physical button to make contact for lock to open the doors downstairs).

I see someone already made it work on similar intercom here:

Elvox 8879 as generic analogue intercom -> nuki opener

Hi, after over one year of try and error, my elvox 8879 is working with the nuki opener : opening the door -> ok ring detection -> ok ring to open -> ok doorbell suppression -> ok Here is my manual: 1. Disassembling First of all you have to remove both bus wires (from 1 and 2), then you can screw of the intercom from the wall and now you can carefully solve the circuit board from the case of the intercom. 2. Soldering: Soldering of the blue and violet wire to the back (!…

For me the most important feature to work os RING TO OPEN.
I dont need anything else to work.

Please if you have any ideas how to connect it to work please share it here in this forum. That would be great help.

Thank you very much in advance!
Robin

Unfortunately you need all functions to work for ring to open! For Ring to open the opener needs to recognise a ring, and the ability to open the door, what are all necessary wires for the opener, sorry! But the soldering tutorial a User wrote before me is not a way for you?
