Keypad 2 NFC needs a Matter compatible lock, which is used for provisioning credentials into the lock and the mobile wallet. The Opener can’t do that therefore it’s not compatible and you need one of the Nuki Smart Locks for this. Later this year a Smart Module should become available which can most likely do what you want.
If you want to hack this together with a Smart Lock, you could either generate some sort of “fake lock” on which you mount a real Smart Lock and which shortens a contact that actuates your strike when it is unlatched or you use one of the APIs (e.g. matter, mqtt) to create an automation (in Home Assistant, Apple Home) which shortens your strike whenever the Smart Lock gets unlocked.
The Smart Module sounds promising and exactly what I’m after.
I also like the API route, wondering if it is possible without having the Smart Lock actually moving? I don’t mind sparing a smart lock for this purpose for the time being, but would rather have the smart lock not make sound in the process of using the API. Any ideas?
If you never lock the Smart Lock it is always unlocked and an additional unlock command from the Keypad should trigger some activity on the mqtt or matter API (lock state change to unlocking or at least a lockAction event) without the lock actually moving.
Oh that’s nice. So the NFC is always used to unlock (unlike the finger print which can perform lock and unlock action)? This is really some good insight.
Since I didn’t receive my Keypad 2 NFC yet I wonder if the Home Assistant Matter integration (or Nuki integration) exposes the lockAction event.
