I have 3 LED ceiling lamps, unfortunately they're using some proprietary protocols for communication. The chip used in remote is PL51WT020: PL51WZ020 (PMicro website)

Is there a way to control the lights using RaspberryPi (other then emulating remote keypresses)?

The lights have two LEDs (dimmable, warm-cold white LED and color LED)- is there any possibility to change the LED driver to one with Alexa built-in?

Thanks for your help!

  • If you want to change the built-in driver it would be more useful to see that driver and the LEDs. Depending on the LEDs something like this could be a solution, but we lack a lot of info.

Replace the controller in the with example Electrodragon ESP32-C3 Mosfet Drive LED Controller, and flash it with example Tasmota firmware.

The "Electrodragon" deice has four MOSFET channels, so it can drive your CW, WW and two colors.

Tasmota has a Belkin emulator or Philips Hue that can be integrated with Alexa.

There is other devices and firmware that can do the same, so the above is just examples.
