Elgato Key Light Automator is a small script that turns Elgato Key Lights and Key Light Airs on and off without needing the physical Stream Deck controller that normally accompanies them. If you use these popular studio lights for video calls, streaming, or content creation, this lets you toggle them from your computer instead of buying or fumbling with a separate button pad. At a basic level, the script communicates directly with the lights over your local network. Elgato lights are actually internet-connected devices, so they can receive instructions from other devices on the same Wi-Fi. Instead of pressing a physical button, you run a command on your computer and the script sends the on or off signal to the lights for you. The README doesn't go into detail on exactly how it identifies your lights on the network or what specific commands it sends under the hood. This is useful for anyone who owns Elgato Key Lights but either doesn't have a Stream Deck or would rather automate their lighting setup. For example, if you're a remote worker who takes a lot of video calls, you could fold this into your morning routine to turn on your lights automatically. Content creators and streamers might use it as part of a larger automated setup that adjusts multiple things at once when they start recording. The project is built using Node.js and includes automated testing through a framework called Jest. The code itself is straightforward, you download it, install the dependencies, and run a single file to get started. There's no graphical interface or menu, it's purely a command-line tool, which makes it lightweight and easy to fold into other automated workflows or scripts you might already have running on your machine.
