Bluetooth Tracking (Samsung)

I’m currently trying to track in devices (in this case a Samsung Galaxy S21) with Bluetooth.
Unfortunately I can’t do that. It will never be found.
I tested both bluetooth_tracker and bluetooth_le_tracker.

The config looks like this:

bluetooth:
  device_tracker:
    - platform: bluetooth_le_tracker
      track_new_devices: false
      interval_seconds: 30
      consider_home: 10

The Devices yaml looks like this:

samsung_handy:
  name: "Samsung Handy"
  mac: "BT_F0:CD:31:9C:7E:4F"
  icon: "mdi:cellphone"
  track: true
  hide_if_away: false

Have any of you ever done this? Would be very grateful for some help.
PS: I can’t track the phone via the app and the phone isn’t on WiFi either.

The above looks incorrect.
Usually mac addresses are just pairs of hex and colons. T is not part of hex and not underscore either.

According to the documentation, the prefix “BT_” must be included in Bluetooth. However, I have already tried this with and without BT. Unfortunately, that doesn’t work.

I am using BLE transmitter from companion app with esphome BLE trackers around the rooms. If you just want to use Home Assistant OS BLE, you can also use Bluetooth LE Tracker.

That’s exactly what I would like to do. I just didn’t manage to track a Samsung phone. Can I motivate you to test it out and see if it works for you?

For me, after enabling it companion app, using Passive BLE monitor custom integration works perfectly.

I added manually UUID into integration and it tracks if it can receive the BLE signal or not (assuming you have Bluetooth controller)
