Ah I see, because the soldering you connected the opener directly to the lines, and there I understand the analogue configuration for just close/open the connected circuit over the opener. But can the opener still recognise your bell signal then?
Ok understand. That’s a kind of adaptive bus recognition?
Does someone know if it works with the elcom i2 bus?
Like the topic says, the BVM-100 / BFT-200 / RSR-200 are using i2 Bus. With some soldering or use tape we set this one up in Nuki Opener as “analogue/generic”, even though it’s the Elcom i2 Bus
Always keep in mind, unless you have a special module installed in the house ringing system, you have to “active” the handheld by ringing on the house door.
If you dont ring e.g. downstairs, the i2 bus is not activated and Nuki will not open the door for you.
If the system is “active” is signaled by the red LED on the handheld on your wall, for mine its about 2-5 Minutes active after ringing downstairs. In this timeframe, you can open the as often as you want - will quit if you pickup the small telephone 
Thanks for explaining 
I noticed it too, that I can’t just buzz the door open at any given time (even before installing Nuki). It is required to ring the doorbell at the front door to activate the buzzer and then only can you open the front door.
As I’ve just installed the system yesterday and didn’t have much time to test it yet I have one question about the ring-to-open via RSR-200 though: Does the doorbell-suppression work?
They way I understood it, is that the RSR-200 allows the Opener to connect as a “second” doorbell. It gets the ring-signal from the yellow cable and knows what to do then. That’s it. Please tell me I’m wrong
The description of the rek221y sais, it is possible to reconfigure the behavior at the door unit. So you can open the door without ringing.
You got it already. Enjoy ringing in the middle of the night since you cannot suppress the bell 
I am happy with it for 2 years now.
Mhm… ok. Good to know. I’ll report how happy my girlfriend is, when I come home at night and wake her up
BTW: is there a quick and easy way to temporarily deactivate the smart-unlock? Use case is, that I’m in the volunteer fire department and if I’m out on a call in the middle of the night I’d like to come home quietly (aka with an old-school key ) to not wake up my girlfriend with the Nuki unlocking the door.
Deactivate bluetooth / activate flightmode while approaching your door would be the easiest way.
The REK221Y is a bit of a different system than the BVM-100 / BFT 200 etc.
There is also a different topic on this one and seems like it wont work at all 
I read the whole thread and I’m a bit confused. I have a BFT-210. Can somebody tell me which steps I have to perform to get my Nuki Opener installed? Will I be able to surprise the bell? If not I’m going to send it back anyways, no use in a multi person household. Thanks in advance!

Hey David,
That looks like a picture of the Elcom Touch wiring? I also have the Elcom Touch. Did you somehow get it to work with the opener?
Thanks

Would be awesome if you could explain how you made the BFT-210 working If you’re german, please also in german, cause my english isn’t very well 
Hi Jens, did you manage to connect?
I’m having the same device and struggling to get the opener integrated.
Many thanks

Anything new Dennis?
