The `mqtt` 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.
|
|
|
|
To use this device tracker in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
device_tracker:
|
|
- platform: mqtt
|
|
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: integer
|
|
{% endconfiguration %}
|
|
|
|
Example JSON you can publish to the topic (e.g., via mqtt.publish service):
|
|
|
|
```json
|
|
{
|
|
"topic": "location/paulus",
|
|
"payload": "home"
|
|
}
|
|
```
