Octolight: add physical button/switch with raspberry?

Hello all,

I have Octoprint installed on a Raspberry 4 for my Ender 3. With two LM2596 DC/DC step-down converters, the power supply of the Ender 3 supplies the raspberry and a 12V LED strip. With two KY-019 5 V relay modules I can switch the Ender 3 (with plugin PSU Control) and the LED strip (with plugin Octolight) on and off.

Is there a way to put a small physical button on the printer and use it to turn the LED light on and off?

Greetings from Germany,

Maybe the physical button plugin would get you close to what you need?
