Create device_tracker entity for BM2 devices

I’d like to create (or have it created automatically by OMG like for Mi Band etc. (BLE gateway | OpenMQTTGateway v1.6.0)) a device_tracker.my_bm2_battery_monitor entity now that BM2 and it’s German rebranding is/will be fully supported by OMG.

I thought: why not? With BM2 we can track cars, motorbikes, quads, jetskis… and I want to know if my car/motorbike/… is at home or not.

  1. How to create one manually from MQTT to HA based on OMG data?
  2. What is needed to support this “out of the box” by OMG?
