I recently purchased a Nuki Keypad 2 as an accessory to unlock my front door with fingerprint and code. While the keypad can be directly connected to the Nuki Smartlock, I was wondering why it is not supported as a thing in OH.
It would be great to use it for additional use cases as well, e.g. have a different code to open the garage door, or react to unlock events from certain users, e.g. send a notification after a certain code was entered, disable the alarm system, etc.
Is the Keypad 2 not accessible via API (e.g. through the Nuki Bridge) or is it just that the binding does not support it?
Unfortunately no, Nuki binding uses Bridge HTTP API which only supports basic lock actions.
There have been such feature requests like this, but it was never implemented. It seems like bridge API is no longer updated and future updates are focused on mqtt/matter.
+1 on this. Being able to access the keypad would be awesome!
In the meantime, I’m thinking on how to integrate my Nuki Ultra + Keypad 2 into the alarm system without accessing the keypad. Of course the rule could be “if Nuki is locked –> activate alarm system”. But then the alarm system would also be activated if one locks the door from the inside, which would directly trigger the alarm if motion sensors are being used. Or am I missing something / has someone found a way how to activate the alarm with the Nuki Ultra / Keypad 2?
you could do the other way around. I have linked my alarm with openhab (it closes a potential free contact when alarm is on). So when I activate the alarm, I have openhab close my door 30s later for example..
I hope it’s not to late for my answer, but I’m new to this forum.
I’m testing some things with openhab since last year, now I have a Nuki lock too and run the mqtt binding over mosquitto. At mqtt you can ask for lock actions and lock is another result than lock’n’go. You can configure your keypad to do lock’n’go by pressing the backspace. So you can activate your alarm only by leaving your home.
At the following link you can get the full api of Nuki mqtt:
At the next link you can find an example of binding Nuki lock over mqtt to openhab:
