Bluetooth LE Tracker | Instructions for integrating bluetooth low-energy tracking within Home Assistant. |
|
Local Polling | 0.27 | 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
.
This platform requires pybluez to be installed. On Debian based installs, run
sudo apt install bluetooth
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 configuration.yaml
file:
# Example configuration.yaml entry
device_tracker:
- platform: bluetooth_le_tracker
{% configuration %}
track_new_devices:
description: If new discovered devices are tracked by default.
required: false
default: false
type: boolean
track_battery:
description: Whether the integration should try to read the battery status for tracked devices.
required: false
default: false
type: boolean
track_battery_interval:
description: Minimum interval to ask the device for its battery status. The battery status will be checked at most once every interval. If track_battery
is false, this will be ignored.
required: false
default: 1 day
type: time
interval_seconds:
description: Seconds between each scan for new devices.
required: false
default: 12
type: integer
{% endconfiguration %}
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.
Enabling the battery tracking might slightly decrease the duration of the battery, but since this is only done at most once a day, this shouldn't be noticeable. Not all devices offer battery status information; if the information is not available, the integration will only try once at startup.
Rootless Setup
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 and hcitool 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\``
sudo setcap 'cap_net_raw+ep' `readlink -f \`which hcitool\``
A restart of Home Assistant is required.
For additional configuration variables check the Device tracker page.
