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?
