This integration creates a composite device_tracker entity from one or more other entities. It will update whenever one of the watched entities updates, taking the last_seen, last_timestamp orlast_updated (and possibly GPS and other) data from the changing entity. The result can be a more accurate and up-to-date device tracker if the "input" entities update irregularly.

It will also create a sensor entity that indicates the speed of the device.

Currently any entity that has "GPS" attributes (gps_accuracy or acc, and either latitude & longitude or lat & lon), or any device_tracker entity with a source_type attribute of bluetooth, bluetooth_le, gps or router, or any binary_sensor entity, can be used as an input entity.

After it has been downloaded you will need to restart Home Assistant.

This custom integration supports HomeAssistant versions 2023.7 or newer.

Composite entities can be created via the UI on the Integrations page or by YAML entries.

To create a Composite entity via the UI you can use this My Button:

Alternatively, go to Settings -> Devices & services and click the + ADD INTEGRATION button. Find or search for "Composite", click on it, then follow the prompts.

The remainder of this section describes YAML configuration. Here is an example YAML configuration:

composite:
  trackers:
    - name: Me
      entity_id:
        - entity: device_tracker.platform1_me
          use_picture: true
        - device_tracker.platform2_me
        - binary_sensor.i_am_home

• default_options (Optional): Defines default values for corresponding options under trackers.

  • require_movement (Optional): Default is false.
  • driving_speed (Optional)

• trackers: The list of composite trackers to create. For each entry see Tracker entries.

• entity_id: Specifies the watched entities. Can be an entity ID, a dictionary (see Entity Dictionary), or a list containing any combination of these.
• name: Friendly name of composite device.
• id (Optional): Object ID (i.e., part of entity ID after the dot) of composite device. If not supplied, then object ID will be generated from the name variable. For example, My Name would result in a tracker entity ID of device_tracker.my_name. The speed sensor's object ID will be the same as for the device tracker, but with a suffix of "_speed" added (e.g., sensor.my_name_speed.)
• require_movement (Optional): true or false. If true, will skip update from a GPS-based tracker if it has not moved. Specifically, if circle defined by new GPS coordinates and accuracy overlaps circle defined by previous GPS coordinates and accuracy then update will be ignored.
• driving_speed (Optional): Defines a driving speed threshold (in MPH or KPH, depending on general unit system setting.) If set, and current speed is at or above this value, and tracker is not in a zone, then the state of the tracker will be set to driving.
• entity_picture (Optional): Specifies image to use for entity. Can be an URL or a file in "/local". Note that /local is used by the frontend to access files in <config_path>/www (which is typically /config/www.) You can specify file names with or without the "/local" prefix. If this option is used, then use_picture cannot be used.

• entity: Entity ID of an entity to watch.
• all_states (Optional): true or false. Default is false. If true, use all states of the entity. If false, only use the "Home" state. NOTE: This option is ignored for entities whose source_type is gps for which all states are always used.
• use_picture (Optional): true or false. Default is false. If true, use the entity's picture for the composite. Can only be true for at most one of the entities. If entity_picture is used, then this option cannot be used.

For watched non-GPS-based devices, which states are used and whether any GPS data (if present) is used depends on several factors. E.g., if GPS-based devices are in use then the 'not_home'/'off' state of non-GPS-based devices will be ignored (unless all_states was specified as true for that entity.) If only non-GPS-based devices are in use, then the composite device will be 'home' if any of the watched devices are 'home'/'on', and will be 'not_home' only when all the watched devices are 'not_home'/'off'.

If a watched device has a last_seen or last_timestamp attribute, that will be used in the composite device. If not, then last_updated from the entity's state will be used instead.

If a watched device has a battery_level or battery attribute, that will be used to update the composite device's battery_level attribute. If it has a battery_charging or charging attribute, that will be used to udpate the composite device's battery_charging attribute.
