Shelly devices not forwarding iBeacon messages

## Intro
Hi @agittins ,

Really love the work you've done on Bermuda and it's promising to be very solid if I can just get it to work. Need a bit of support and I've searched far and wide, but cannot really find something to resolve this issue.

I have a BT dongle in the HA instance, and 8 additional shelly plus devices throughout the house. This in theory should work really well, and for some devices it does.


I have all of the shelly's configured as active and logged into the web interface to ensure the script installed by HA is activated.

In bermuda, I've added tracking for a few BT entities and for some of them it works flawlessly,


## Configuration




## Describe the bug

As shown above, some devices report really well, but an android phone (Samsung A35) configured and selected as an iBeacon and set up with the companion app only checks in really really infrequently and all statuses are typically shown as Unknown. When the device gets picked up at times, it quickly jumps back to unknown mode thereafter.


The device was on charger, connected to home SSID and in the living room during the entire time shown

## Diagnostics

(for now I'm not uploading diagnostics, as it contains all the sensitive information I blurred out in the images)

## Conclusion
Is there anything in particular that I need to know about ibeacon devices and why their tracking doesn't work as reliably as expected?
