MQTT device tracker configuration

I tried the device tracker configuration by MQTT as described here and send these MQTT messages:

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

mosquitto_pub -h 127.0.0.1 -t homeassistant/device_tracker/a4567d663eaf/config -m '{"state_topic": "a4567d663eaf/state", "name": "My Tracker", "payload_home": "home", "payload_not_home": "not_home", "json_attributes_topic": "a4567d663eaf/attributes"}'

MQTT explorer shows the messsages:

I am quite sure they reach home-assistant as other sensors are also found and data updated


But the device tracker is not there.

What have I done incorrectly and what should I do to add the device tracker?
How can I show the data of the device tracker on a map?

Brother, I have the same problem, how do you solve it?

I think you have to define the sensors under device_tracker, and then connect them to a person using the ui.
