3A LED strip controller
From Wildsong
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.
I am thinking of a custom controller for a simulated fireplace. But also I could just do ESPHome as an option.
