The new lock, called The Bolt, is BLE only. They’re going to ship a separate device they call the Bridge which will provide wifi to BLE. You’ll be able to get the lock without the bridge if you don’t need it.
They don’t say, but it would make sense if the bridge unit is a plug in.
[quote]Bridge: Instantly Responsive WiFi
To conserve battery life and allow for instantaneous connectivity, we’ve removed the integrated WiFi chip from Lockitron Bolt and put it into Bridge. Bridge connects Bolt to the internet and allows for full, instantaneous control anywhere you have internet access. Whether you just want to let a guess in or forgot to lock your door on the way to work, Bridge is the perfect solution. It’s important to note that Lockitron Bolt is a standalone product and doesn’t require Bridge for local, Bluetooth Low Energy access or to share access with family and friend. This means you can choose the best Lockitron Bolt or Bolt+Bridge solution to suit your needs and budget.
