I bought the NUKI opener believing it to be compatible- because my intercom looks identical to one that is. But it turns out, I have the bus version. Anyway, I tried wiring up as the generic bus options and I can’t get it to detect the unlock or doorbell signals (I’m using iOS).
Before I continue, has anyone had any luck setting up a bus BPT system yet? I have no idea why it wouldn’t work- I don’t think the signal is encrypted.
If I can’t get to work, I’m going to attempt to solder to the board to set up as a generic analogue intercom but my knowledge is quite limited. I’ve located the button that unlocks the door and used a bit of trial and error to work out where to touch the blue and purple wires on the back of the circuit board. Before I get the soldering iron out, does this make sense? It seems to give a reliable signal to open the door, it just feels weird that its a random 2 very close bits of solder on the back of the button. And I’m not sure if I should be looking for a different spot to put the GRND wire.
The next problem is (the hidden) ring detection mode. I don’t think I want to suppress the ring but it’d be good if the NUKI could detect when the doorbell is rung so that it can open automatically (I get a lot of parcels at 4:30am that are driving me crazy!)
The loudspeaker is actually the same speaker as in the handset, which is connected with 3 pins to the board. I’ve experimented with connecting straight to the pins with no luck. I had to borrow my friend’s android phone because weirdly this mode isn’t compatible with iOS. Any ideas? It would be greatly appreciated. I feel like I’m close to getting this solved for all BPT bus intercom owners.
