Add Picture to Device Tracker Entity

Moin,

I do not get my head around this. In mqtt_sensors.yaml I have a few sensors:

- device_tracker:
    name: Location
    default_entity_id: device_tracker.tesla_location
    unique_id: teslamate_1_location
    device: *teslamate_device_info
    json_attributes_topic: "teslamate/cars/1/location"
    entity_picture: /local/TM3LRAWD.png
    icon: mdi:crosshairs-gps

I’ve added the entity_picture line - but the tracker still has no image. File and path should be okay. I also tried /www/ instead of local. But when I review the sensor in the inspector. The picture is missing complexly.

Where am I wrong?

Please explain what you want as result. That’s not how that works…

The Tracker is used in my Dashboard. And I would like to replace the icon with a picture.

This is available on a tablet in the house for everyone to see where the cars are:
