I’m mildly surprised OP’s laptop keeps the bluetooth radio powered up while asleep, but I would be a lot more surprised to find one that doesn’t work with USB HID.

Node Red by far gave me the best automation for numerous lights. X minutes after sunrise, it iterates every light that is on and calls turn off with a fairly long (2 min?) transition time, so the lights all gradually fade off.

It’s been running for years without me needing to touch anything, it doesn’t care if you replace/rename any lights, and the slow fade when it’s still getting brighter outside makes the change invisible.

I’ll bet you could do the same thing without Node Red, but nowhere near as easily.

That isn’t even a terrible idea - with that many conductors, you should be able to carry tens of amps. Use two for “Data” (detecting charger) and you’ve got… 21 positive and 21 negative. I’d not be surprised to see that hit 100W without catching fire.
