is there any news here? I have the same system and the same problems. I can’t lock the setup properly because the door won’t open after the doorbell rings. apparently the ringing is not recognized correctly. I can open the door in the app. RTO doesn’t work. the suppression doesn’t work either.
I have the feeling that Nuki is not developing the opener any further. there are no updates.
Same issue here with BTS-850-02. opening via the app works fine, just the pressing to ring from outside does absolutely nothing 
No solve found yet.
Same here with Siedle AIB 150-01, no rings detected. Tried normal setup, basic setup, both generic setup. Nothing works.
Hi! Are the rings not detected at all, or just no opening after ringing!?
I‘ve installed my opener yesterday and tried differend cabeling and settings. Nothing worked for me now.
I tried the app suggested cabeling and the minimal with only red and black.
Also i tried different settings from the BTS and both generic bus.
When installing the opener it recognizes when i press the open button on the BTS and when i press the ring outside.
Pressing the open button in the app or press the ring again for the rto function doesn‘t anything.
Some more tips for the problem?
Thank in advance
…würde mich sehr interessieren da ich exakt das gleiche Problem habe und schon ein paar Tage mitlese und diverse Dinge leider ohne Erfolg ausprobiert habe.

Hallo, ich habe auch BtS-850-02 und egal was ich versuche es funktioniert nicht. Wie kann ich auf die Beta kommen ?
Same problem here. I tried everything multiple times. The ringing and the opening via intercom work, opening via app doesn’t, so I can’t finish the setup.
Tried delay and disabled all suppressions, no luck.
Multiple factory resets, dozen times rewired…
Contacted support now, maybe they can do something…
03/2024 Opener Version 1.10.1 Siedle BTS 850-02.
Same issues. Intercom itself is working. Configuration recognize pressing button on the intercom and the Bell but the app does not open anything. Gonna try the factory reset thing tomorrow. Already Emailed the support. Really frustrated!
Hi, got the Nuki Opener today (03.04.2024), firmware 1.10.1. Intercom is Siedle BTS 850-02. During the configuration, the app asks me to push the door opener, then the app loads but nothing happens, the configuration cannot be closed. I had a phone call with the support. They asked me to take the batteries out for over ten minutes, reset the opener and restart my phone. Didn’t help. Had another phone call. I was asked to make the configuration without the bridge. Didn’t help. I was asked to email the support team with more details and pictures so that they can have a look. They said they will reply within a few days. Will keep you guys updated
I messaged the Nuki Support, and after a few „are you stupid like every customer“ question somebody actually took care of me and took a closer look.
They wanted me to try multiple things, and also use the minimum cabeling (noticed in a few posts above). None of that worked.
They then asked for an invite to the opener (I assume this will only work if you own a bridge) so they could change some parameters. After 2 changes back and forth the opener actually does work now.
I asked them what they did change, because I assumed that they changed some „Expert Settings“ that are hidden somewhere like the supression delay.
They told me it‘s something only they can do and I have no influence about.
Something in my head doubts that and I wonder why.
But well, if they want more support tickets for that…Instead of posting the actual solution here.
So the solution would be: Message the support, give them as much details on what you already did and send them images of the cabling. They will eventually figure it out.
I think calling them won‘t work, unless they will connect live to your opener and change the parameters, but I doubt that they will do that.
Hey,
so heres my update: Like Jona here, im in touch with the support. I also invited the support to my Opener, they told me they changed settings. Now the app doesnt even recognize when i have to press the button on my intercom anymore. I answered the email and ask if i may reset my opener to factory or would that just reset their new settings?
Until now no answer to that. (which is okay since i replied just a few hours ago) 
For now i just hope we solve this Problem but even if not im not gonna send it back because im already hooked to the Nuki. I love, i dont have to register and just download an app. I think sooner or later it will work.
Gonna keep you guys updated.
So, the customer came back and the following happened:
The final email now came that says that the system is NOT COMPATIBLE. This can also happen with “verified systems”. They are unable to further help me from distance and wrote that there are various factors that can hinder the compatibility and that they cannot make any general statements hereto.
As I am still in the 30 days window, they propose that I return their product.
PLEASE REFRAIN FROM BUYING THE NUKI OPENER IF YOU HAVE THE SIEDLE BTS 850-02 and save yourself some trouble and interaction (9 days of daily emails for me) with a rather moronic customer service.
I will try and buy the Ring Opener and provide some feedback on this forum as it is related imo.
Just wanna join in the line of people having issues with the BTS-850-02.
It worked for me, when I first set it up like 1.5 years ago (I had issues with it not recognizing the doorbell at first, but randomly it just worked back then. Then the bell system broke down in the whole building and after it being repaired I am unable to reconfigure the opener. It just won’t recognize the open door button anymore, even though the LED pattern changes, so it seems to recognize that a button got pressed.
Anybody got a fix for this? I am at my witts end, customer support offered me a replacement part or my money back and I went for the replacement opener (as it had worked in the past) - but the new one doesn’t work either.
I’ve been thinking about switching to the Ring Intercom as well, but I really want to get the Ring2Open feature back.
Short Update from my side. I got a new Opener sent and tried that out but no progress. I invite the Support to my new opener. Lets see if they can figure somthing out. Sadly i dont belive this problem is going to be solved.
greetings from germany.
Really rooting for them finding the issue on your replacement Opener… Keep us updated please
Last Update from my side. They gave me advice and after a few days of no responding from my side, they closed the ticket (didnt had time). I tested the advice and it still doesnt work. Im exausted, it does NOT work. I cant complete the configuration since pressing the button is not recognized, i wont reopen the ticket again. I just use the lock with the bridge, without the opener and get a fingerbot for the button.
Im dissappointed but im really happy with the lock itself, so i wont return anything.
I read about soldering the wire to the button itself and configuring it as a gate instead of normal door, that could work as well… but I am not sure I really want to solder anything
I live in a big house and yeah this maybe work but its not my intercom and i dont want to solder anything to it because if i damage it, the landlord will not be amused. 
A fingerbot is just “glued” in place on top of the case and is pressing the button as if i would press it with my finger. I have a Smarthome and can configure it together with my Nuki lock. Its also included in my Smart Home. I use Home Assistant if someone wanna know. I was just hoping that nuki would provide a complete solution so i dont need to fiddle with the intercom myself.
Yeah, I am in the same situation, except me being the landlord - but still, soldering something on there is not something I am looking forward to…
I might just try the Ring Intercom first, as it seems to be well integrated into Home Assistant - might be something for you to look into as well.
