The mqtt_json device tracker platform allows you to detect presence by monitoring an MQTT topic for new locations. To use this platform, you specify a unique topic for each device.
{% linkable_title 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_json
devices:
paulus_oneplus: location/paulus
annetherese_n4: location/annetherese
{% configuration %} devices: description: List of devices with their topic. required: true type: list qos: description: The QoS level of the topic. required: false type: string {% endconfiguration %}
{% linkable_title Usage %}
This platform receives JSON formatted payloads containing GPS information, for example:
{"longitude": 1.0,"gps_accuracy": 60,"latitude": 2.0,"battery_level": 99.9}
Where longitude is the longitude, latitude is the latitude, gps_accuracy is the accuracy in meters, battery_level is the current battery level of the device sending the update.
longitude and latitude are required keys, gps_accuracy and battery_level are optional.
