Last year I spent way too much time wiring up a janky contraption using a raspberry Pico wireless board and couple of optocouplers, so I could simulate a button press on a USB switch used as a KVM between my work notebook and personal PCs. So I could then call the pico board via http from a button push on an Elgato streamdeck.

While it worked, it was still a bit slower than me simply pressing a button on the little wired remote that came with the USB switch.
