We have received numerous reports that this integration will have a big impact on the performance of the server.
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
This platform requires pybluez to be installed. On Debian based installs, run
$ sudo apt install bluetooth libbluetooth-dev pkg-config libboost-python-dev libboost-thread-dev libglib2.0-dev python-dev
Before you get started with this platform, please note that:
- This platform is incompatible with Windows
- This platform requires access to the bluetooth stack, see Rootless Setup section for further information
To use the Bluetooth tracker in your installation, add the following to your
# Example configuration.yaml entry device_tracker: - platform: bluetooth_le_tracker
- device_id (Optional): The device ID for the Bluetooth device to be used for tracking. Defaults to
- track_new_devices (Optional): If new discovered devices are tracked by default. Defaults to
- scan_duration (Optional): How long should the scanner be looking for BLE devices. Defaults to
- interval_seconds (Optional): Seconds between each scan for new devices. Defaults to
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.
Normally accessing the Bluetooth stack is reserved for root, but running programs that are networked as root is a bad security wise. To allow non-root access to the Bluetooth stack we can give Python 3 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/homeassistant/homeassistant_venv/bin/python3
A restart of Home Assistant is required.
