Configuration for ESP32
{"NAME":"Yeelight Meteorite","GPIO":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,420,0,419,0,0,0,0,417,418,0,0,0,0,0,416,0,0,0,0,0,0],"FLAG":0,"BASE":1,"CMND":"SO37 128 | SO92 1"}
Flash only with tasmota32solo1.bin build for ESP32-SOLO-1. Flashing instructions for tasmota32 firmware.

Applying the template will add two SetOptions to allow both PWM lights to be controlled: SetOption37 128 and SetOption92 1

White Light and RGB can be split for better control.

Notice: there is some variant that changed RED channel from GPIO33 to GPIO22. If yours is always RED, then change manually PWM1 from GPIO33 to GPIO22

  • GPIO33 - red - PWM1
  • GPIO26 - green - PWM2
  • GPIO27 - blue - PWM3
  • GPIO21 - cold white - PWM4
  • GPIO19 - warm white - PWM5
  • GPIO23 - Night Light (not defined in template)
  • GPIO22 - ON/OFF (function unknown)
