Help reading data from an Inkbird/Tempwise BG-BT1W bluetooth thermometer

ESPHome

Hi guys,

I’ve got an Inkbird/Tempwise BG-BT1W bluetooth meat thermometer

H98e493a909bf408193c1d924b712a2d941600×1600 82.2 KB

and I was wondering if someone could please help me use ESPHome to extract the data from it please?

I’ve got ESPHome running for some other devices but these devices have been decoded already so it was easy to implement.

Here’s the info from nRF Connect:
