Addition of different service_uuid for older ThermoBeacon Hygrometer

I have recently transitioned to HA (Core) on Ubuntu 20.10 with my BriFit Thermobeacon Hygrometers from a bespoke Cacti implementation, and it’s been fantastic to find that (almost all of) my thermobeacons work out of the box with HA.

However, I have a couple of early purchases (which look exactly the same as the more recent items), which have different service_uuids to the newer models. The older and newer models both report with manufacturer_id=17.

How easy would it be to add the older service_uuid(s) to the manufacturers_data so that my older thermobeacons work too?!? Below is a snip from the Bluetooth debug log showing the two older models and one of the more recent ones.

OLDER: 00001800-0000-1000-8000-00805f9b34fb - not recognised
NEWER: 0000fff0-0000-1000-8000-00805f9b34fb - works fine

If there is a simple change under the bonnet that I could do myself to enable these older devices, I’d be happy to do that!

Many thanks in anticipation.
