So far device_tracker entities are not supported by the MQTT discovery mechanism.
I am currently building an IOT device to track small key fobs with vendor-set ids. I would like to be able to just plug them in, publishing an appropriate config to the MQTT discovery mechanism and the key fob showing up as a new entity in my home-assistant the first time I plug in a new key fob.
I have already had success using the mechanism for sensors and am wondering why is hasn’t been implemented for the device_tracker. Are there any limitations, which do not allow for it?
Thank you for your support and work on home-assistant so far!
