The Schlage Connect deadbolt uses Z-Wave rather than Wi-Fi, so it pairs with your own Home Assistant or Hubitat controller instead of a Schlage cloud account. The keypad and the physical key keep working without any network.
You need a Z-Wave controller to get any smart features. Schlage’s Wi-Fi Encode line is the opposite trade: it runs through the Schlage Home app and account, so choose Connect if you want the lock to stay local.
