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?

  • 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 panel with (as an example) Electrodragon ESP32-C3 Mosfet Drive LED Controller, and flash it with (for 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 are other devices and firmware that can do the same, so the above are just examples.
