3A LED strip controller

The 3A controllers have a Zigbee module in them. See User manual which contains almost no information but does have a pinout.

I am thinking it looks like the controller it has 4 MOSFETs and the only connections between the module and the board are 3v+ Gnd and 4 IO lines.

It should be pretty easy to replace the module with an ESP32. Then I can get full access to program it; currently it's a black box.

I am thinking of a custom controller for a simulated fireplace. But also I could just do ESPHome as an option.

After these get reset (like when the power supply died) they can be paired again,

1. power cycle
2. within 30 seconds or so go to Home Assistant to the Zigbee integration and do "add new device". It should find and pair.
