How does Bridge work?
Lockitron Bridge is an optional accessory that connects Lockitron Bolt to the web. By default Lockitron Bolt is a Bluetooth Low Energy only device - this means that you can share access, automatically unlock the door via Sense and control Bolt even if your home's WiFi or power is out. Bridge gives you the ability to control Lockitron remotely as well as see the state of Bolt remotely.
Bridge is powered by a standard USB Micro 5v DC power supply that plugs into a nearby wall outlet. The optimal range for Bridge to Bolt is 10-15 feet. Currently each Bridge only supports one Bolt device.
