ThermoPro TP393 Not Reporting Battery over bluetooth?

I have a ThermoPro TP393 setup using bluetooth proxies and then the official ThermoPro integration. All works well and I can connect to them and get the temperature and humidity. The one thing I can’t seem to see however is the battery percentage. I know these have a rechargeable battery but I would still expect the percentage to be broadcast especially since the app can pick it up. Am I missing something or is it just not supported?

Yeah seems incomplete. Just had a sensor go dead and would have been nice to have been warned.

Same here. Had battery go dead, and it would have been nice to have an automation capable of warning me.

I’m not terribly familiar with how this all works (github, etc.). How should one go about requesting this be added to the integration?

Thanks in advance!
