It's nerve racking trying to hack a LED panel with 0 AC isolation and 300V DC at one point, the lowest voltage in the system is around 70V DC
Now got it working with HomeAssistant and esphome with color temp and brightness control.

I'm happy about the hw inside the SONOFF #Zigbee temperature and humidity sensor.
The main sensor is a mems type and properly isolated from the main pcb, none of that DH11 bs.
The controller is a TI CC2530, zigbee chip powered by 8051 Core xD.
