Bluetooth LE Tracker


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.

Requires PyBluez. If you are on Raspbian, make sure you first install bluetooth and libbluetooth-dev by running sudo apt install bluetooth libbluetooth-dev

Requires gattlib, which is not compatible with Windows. This tracker won’t work on Windows!

To use the Bluetooth tracker in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
device_tracker:
  - platform: bluetooth_le_tracker

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.

BT LE tracking requires root privileges.

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 for more information).

$ sudo apt-get install libcap2-bin
$ sudo setcap 'cap_net_raw,cap_net_admin+eip' `readlink -f \`which python3\``

If you have installed Home Assistant with AIO, you need to do the following command, this will grant access to Home Assistant to run the required command.

$ sudo setcap cap_net_raw,cap_net_admin+eip /srv/hass/hass_venv/bin/python3

A restart of Home Assistant is required.

For additional configuration variables check the Device tracker page.
