Open Nuki-Lock by custom App without Bridge

Hi there,

I’m looking for a lock that can be directly opened by a smartphone running a custom App without the need of a bridge.

Reason is that there isn’t always WLAN available to enable the bridge to connect with the NUKI Server. However, users trying to unlocking a door with a smartphone do have internet access through their phone. They might therefore connect our a server to provide the token to open the lock.

To enable this, there must be some sort of challenge response scheme implemented where the lock challenges a user by e.g. a random number which the user/server must process to a token being accepted to open the door.

Does NUKI provide such a functionality?

You can use the Bluetooth API to create your own Nuki client and manage the token/credentials on your server. More information is here: Bluetooth API - Nuki Developers
