Monitor EPEVER Tracer charge controllers via built-in BLE dongle

Hi!

After buying an EPEVER Tracer7810 CPN with built-in BLE connectivity I literally found no way to access its data without their proprietary application. And I didn’t want to wire an ESP32 to it just to talk to its Modbus interface. This thing has bluetooth, my HA host has bluetooth, so this had to work somehow…

Long story short, with the help of Claude I just reverse engineered its Modbus-BLE protocol and build (well, more vibe-coded) a custom integration for this Tracer controller. Others probably work, too.

Maybe this is helpful for somebody else.

Cheers!

Amazing. I will try this out later with my AN series + BLE adaptor.

Thanks, I’ve updated the readme with the information that it is also working with the Tracer AN2206.
