This tracker discovers new devices on boot and in regular intervals and tracks bluetooth low-energy devices periodically based on interval_seconds value. It is not required to pair the devices with each other.
This tracker discovers new devices on boot and in regular intervals and tracks Bluetooth low-energy devices periodically based on interval_seconds value. It is not required to pair the devices with each other.
Devices discovered are stored with 'BLE_' as the prefix for device mac addresses in `known_devices.yaml`.

As some BT LE devices change their MAC address regularly, a new device is only discovered when it has been seen 5 times.
Some BTLE devices (e.g. fitness trackers) are only visible to the devices that they are paired with. In this case, the BTLE tracker won't see this device.
For running Home Assistant as non root user we can give python3 the missing capabilities to access the bluetooth stack. Quite like setting the setuid bit (see [Stack Exchange](http://unix.stackexchange.com/questions/96106/bluetooth-le-scan-as-non-root) for more information).
