Exposes:

• 2x voltage readings for both the relay device (dock) and probe itself
• 1x temperate reading
• 1x probe RSSI
• Manufacturer ID: 36606
• Bluetooth device name: FM210_coded or FM210
• No direct BLE advertisements that I can see from a hci log (or BLE Scanner), at least none that are discoverable by bleak. The services it exposes is only for writing (updating settings) as far as I can tell, and even then its only to set the temperature unit, the device unfortunately does not tell us what this is as far as I can see.

Requirements:

• Active BLE connection, listening to notifications from GATT service "0000ff01-0000-1000-8000-00805f9b34fb"
• When device goes back into the dock / charging device, a final status update is sent on the above service to let the connected client know the probe is charging
• After this last status message, it will disconnect and become unavailable until it is next removed
• Device name is advertised and starts with "FM"
• This is more of a protocol implementation for devices supported by the Probe Plus app more than a specific individual device. I had decompiled the app and converted the decoding functions into Python.

Have attached Python code that is able to decode packets already into dicts - I couldn't figure out how to start a Bluetooth connection in HA in my own integration for this as I kept getting random errors from DBus.

This is actually a pcap file - but GH doesn't allow that type so uploaded as txt instead btsnoop_hci.txt
