I already tried everything from the method to connect to unknown intercoms, but it always ends the same way. Nuki is able to detect the bell but it always fails when Nuki should open the door.
This intercom protocol is very common at least here in Czech Republic, so it will be great if I can somehow help to make it working.
Hi guys, I ve jsut received my opened and was trying to figure out how to wire it to the intercom. I have a Tesla Stropkov 2-BUS too. I am in Cheb Did you made it work finally ? what was the wiring ? Thanks in advance.

With all Tesla 2-BUS devices you need to first pick up the call to be able to open the door. You literally can’t open the door without holding the receiver in hand.
Hi guys, I am also from Czech rep, I have also Tesla. However, I have tested that I can ring the buzzer without picking up the phone… so… maybe it could work. I am hesitating whether to order the Opener…
Hi guys,
It worked for me finally.
No need for me to use the buzzer from Nuki. The one from Tesla was working fine. I simply wanted to have the possibility to open the main door of the building without any key and that way being able to grant access to family or friends when needed.
amazaing news, can you please share your solution with us. My Opener is still gathering dust in my closet, so it would be nice to use him for something much more useful
Hello Tomas,
Hm unfortunately I sold the apartment few months ago and cannot retrieve any pictures of the wiring.
I had the Tesla, the Opener, the smartlock, and the Bridge.
But basically.
When someone was ringing, the Tesla buzzer was ringing, not the Nuki one. I was able to talk to the person downstairs and open the door using the push button of the Tesla.
In the meantime, from the Nuki App, I was able to access both the Opener + the Smartlock using the 4G/mobile Network (I was out of the bluetooth range)
Opener was connected to the same wires as the push button of the Tesla. No need to “answer to someone ringing” which was perfect in my case.
So it was a partial solution that may not satisfy everybody, but in my case it was enough.
Hope this helps.
Honza, may I ask, how was your connection? I didn’t understand if you basicly have normally pick up the phone and then the button for key was working?
Or your button for key on the phone was working even without picking up the phone? (after someone pres the ring button at the door intercom)
Well I sold the apartment several years ago now, but I had an opener, a bridge for remote access, a numeric pad, Nuki smart Lock
The numeric pad was connected via bluetooth to the Smart Lock of the apartment.
The Opener was controlling the main door of the building. I guess I used the same sockets used by the “key button” on the phone so that you can either press the key button, or send the signal to the opener via the Nuki App in order to open the main door of the building.
Thanks to the Bridge I had remote access to the opener and the Smart Lock, so I was able from the Nuki App to open the main door of the building or the door of the apartment wherever I was.
There was no need to have a call from downstairs to open the main door of the building. By picking up the phone, I could press the opener button, or press the Key button to open the main door of the Building.
Hope this helps.
Now I’ve recycled the Opener and I’m using it wired to a Ubiquiti Door Access system. Works like a charm for several years.
Hi Honza, thank you very much for you prompt and competent response.
I checked my bus Tesla stropkov and I have to first receive a phone call from intercom, then I have to pick up the phone and only after these to steps I am able to use key button to open the building door.
Do you have any idea how did you make it that you vere able to open the door without receive a ring and pick up the phone?
Hi Premyls,
Well have you tried to connect the opener on the same sockets as the Key button ?
In my understanding, the opener sends a electric signal to release the magnet of the door or similarly. So if the opener is wired to the same sockets it should work. Unless there’s kind of protection that the Tesla Stropkov “listens” only when somebody rings at the door. You could also try to have the phone always unhooked to see how it behaves.
Do you know what’s the reference of your Tesla Stropkov system ?
Rgds,
Honza
Hi Honza, Thank you for your reply, in our system there is exactly that protection that Tesla Stropkov listens only when somebody rings. I use 2 Nuki openers on other systems, it works properly.
At home, I haven’t tried yet but as the key button doesn’t work without someone rings to me first, I think I cannot use your hint.
Do you have any idea if you can swith off this protection?
Our phone at home is type 4fp 211 03.201 2-bus
And intercom seems as type UDV KARAT.
Hi Premysl,
I would give it a try anyway I know that from Nuki compatibility matrix, basically if you listen to them “nothing is compatible” try to have a look at the wiring logic:
and connect the opener to the same sockets as the “Key button”. Try the BZV- and BZV+ what it does
