My internet connexion goes through 4G = my router is 4G phone like. So I don’ t have any IP address, as I’m considered by my connexion supplier as part of his local network.
Will I be able to connect to Nuki system from outside?
For local operation you need only Bluetooth.
Nuki Pro 3.0 / Nuki Bridge can be operated remotely and for this you need a WiFi.
It doesn’t matter if you have internet via landline, DSL, cable or mobile.
