MQTT Device Tracker
The mqtt device tracker platform allows you to define new device_trackers through manual YAML configuration in configuration.yaml and also to automatically discover device_trackers through a discovery schema using the MQTT Discovery protocol.
YAML Configuration
To use this device tracker in your installation, add the following to your configuration.yaml file:
# Example configuration.yaml entry
device_tracker:
- platform: mqtt
devices:
paulus_oneplus: "location/paulus"
annetherese_n4: "location/annetherese"
Configuration Variables
The payload value that represents the ‘home’ state for the device.
The payload value that represents the ‘not_home’ state for the device.
Attribute of a device tracker that affects state when being used to track a person. Valid options are gps, router, bluetooth, or bluetooth_le.
Complete YAML example configuration
# Complete configuration.yaml entry
device_tracker:
- platform: mqtt
devices:
paulus_oneplus: "location/paulus"
annetherese_n4: "location/annetherese"
qos: 1
payload_home: "present"
payload_not_home: "not present"
source_type: bluetooth
YAML Usage
To set the state of the device_tracker then you need to publish a JSON message to the topic (e.g., via mqtt.publish service). As an example, the following JSON message would set the paulus_oneplus device_tracker to home:
{
"topic": "location/paulus",
"payload": "present"
}
Discovery Schema
MQTT device_trackers are also supported through MQTT discovery. This is different to the YAML configuration from above. Here, the device_tracker can be created via a discovery topic that follows the following topic name convention: <discovery_prefix>/device_tracker/[<node_id>/]<object_id>/config and the JSON message content of a specific format as defined below.
Configuration Variables
A list of MQTT topics subscribed to receive availability (online/offline) updates. Must not be used together with availability_topic.
The payload that represents the available state.
The payload that represents the unavailable state.
When availability is configured, this controls the conditions needed to set the entity to available. Valid entries are all, any, and latest. If set to all, payload_available must be received on all configured availability topics before the entity is marked as online. If set to any, payload_available must be received on at least one configured availability topic before the entity is marked as online. If set to latest, the last payload_available or payload_not_available received on any configured availability topic controls the availability.
The MQTT topic subscribed to receive availability (online/offline) updates. Must not be used together with availability.
Information about the device this device tracker is a part of that ties it into the device registry.
A list of connections of the device to the outside world as a list of tuples [connection_type, connection_identifier]. For example the MAC address of a network interface: 'connections': ['mac', '02:5b:26:a8:dc:12'].
A list of IDs that uniquely identify the device. For example a serial number.
Defines a template to extract the JSON dictionary from messages received on the json_attributes_topic. Usage example can be found in MQTT sensor documentation.
The MQTT topic subscribed to receive a JSON dictionary payload and then set as device_tracker attributes. Usage example can be found in MQTT sensor documentation.
The payload that represents the available state.
The payload value that represents the ‘home’ state for the device.
The payload that represents the unavailable state.
The payload value that represents the ‘not_home’ state for the device.
Attribute of a device tracker that affects state when being used to track a person. Valid options are gps, router, bluetooth, or bluetooth_le.
An ID that uniquely identifies this device_tracker. If two device_trackers have the same unique ID, Home Assistant will raise an exception.
Discovery Example
You can use the discovery protocol to create a new device tracker and set it’s state using the command line tool mosquitto_pub shipped with mosquitto or the mosquitto-clients package to send MQTT messages.
To create the device_tracker:
mosquitto_pub -h 127.0.0.1 -t home-assistant/device_tracker/a4567d663eaf/config -m '{"state_topic": "a4567d663eaf/state", "name": "My Tracker", "payload_home": "home", "payload_not_home": "not_home"}'
To set the state of the device tracker to “home”:
mosquitto_pub -h 127.0.0.1 -t a4567d663eaf/state -m 'home'
