Brian Dorey documents building a remote controller for three Elgato Key Lights using a low-cost ESP32 WiFi module with push switches and indicator LEDs.

This project is an upgrade to the previous blog post where I created a simple remote-control switch to turn on and off a single WiFi-connected Elgato Key Light.

The lights do not have any buttons for manual control, and you need to either use the Elgato Control Center app on a mobile device or the desktop software to change the settings or turn the lights on and off.

The lights retain their previous light level and colour temperature settings, so a simple controller with three push buttons would be ideal to allow remote control without needing to use the mobile app or start the main PC every time we wanted to use the lights.

A 3D printed case encloses the project electronics. The code is written in Arduino.

The project is documented here and the code is on GitHub.
