### Presence detection (device tracker)
|
||||
|
||||
Setting up a device tracker:
|
||||
|
||||
- Configuration topic: `homeassistant/device_tracker/paulus/config`
|
||||
- Example configuration payload:
|
||||
|
||||
```json
|
||||
{
|
||||
"name":"Paulus",
|
||||
"state_topic": "homeassistant/device_tracker/paulus/state",
|
||||
"payload_home": "home",
|
||||
"payload_not_home": "not_home",
|
||||
"source_type": "bluetooth"
|
||||
}
|
||||
```
|
||||
|
||||
- State topic: `homeassistant/device_tracker/paulus/state`
|
||||
- Example state payload: `home` or `not_home` or `location name`
|
||||
|
||||
If the device supports GPS coordinates then they can be sent to Home Assistant by specifying an attributes topic (i.e. "json_attributes_topic") in the configuration payload:
|
||||
|
||||
- Attributes topic: `homeassistant/device_tracker/paulus/attributes`
|
||||
- Example attributes payload:
|
||||
|
||||
```json
|
||||
{
|
||||
"latitude": 32.87336,
|
||||
"longitude": -117.22743,
|
||||
"gps_accuracy": 1.2

|

```bash
|

mosquitto_pub -h 127.0.0.1 -t a4567d663eaf/state -m '{"latitude": 32.87336, "longitude": -117.22743, "gps_accuracy": 1.2}'
