This page details a basic remote control that can be made on a breadboard utilizing push-buttons. The example here is running on an Adafruit Feather ESP32-S2, but it could also work with an ESP32-S3 or ESP32-C6 based devices. The Pico W and Pico 2W can be used as well, but you will need to change the pin references in the code to whichever pins your wire your buttons to.
Code
The code.py file for the remote control is shown below. Same as with the example on the previous page, you need to update the initialization line of code with the IP address of your own light, see here if you don't know the IP.

Neokey 1x4 Version
If you like Stemma QT cables more than breadboards, there is an alternate version of the remote control code that uses a Neokey 1x4 QT instead of the breadboard and push-buttons.
