Presence detection frustration

Hi all

I am getting quite frustrated, so I thought I’d pose the questions here.

I initially tried out device tracking using the android app but its incredibly slow.

I understand that an entity is created to represent the android app (in my case device_tracker.alex_phone. I then link the entity to the person (in my case the entity is person.alexander)

I have successfully setup Bluetooth device tracking with MQTT using this. That works really well, but the examples in the documentation completely confuse me.

I am successfully updating a binary sensor entity with my presence confidence value (in this example sensor.alex_phone) What I am struggling with, is how to associate the sensor entity sensor.alex_phone with a device_tracker entitity. The documentation on HA is thoroughly confusing, and the examples show things like:

device_tracker:

  • platform: netgear

There is nowhere I can find what examples I can use under platform.

Any assistance would be very much appreciated.
