How to tell if Raspberry Pi 3 Bluetoth is working with HASS or not?

Configuration
1

Hi guys

just wondering how to confirm the Bluetooth tracker is actually working and talking to HASS?

I can confirm from terminal that Raspi bluetooth is working (by following this guide https://www.cnet.com/how-to/how-to-setup-bluetooth-on-a-raspberry-pi-3/)

however, is there a way to check if HASS is tracking BT enabled devices?

This is my config file

device_tracker:
  - platform: bluetooth_tracker
    interval_seconds: 10
    consider_home: 180
  - platform: owntracks
    max_gps_accuracy: 100
  - platform: ping
