Use case: Christmas village powered by AA and AAA batteries.
Question: is there any way to automate these items? The only way I can think of a method to do this would be to modify where each items switch is located and wiring in a remote of some sort. But I’m just trying to find a less invasive method if possible, but I’m not holding out a bunch of hope…
Depends if it has to stay battery powered.
If you’re willing to hardwire it, get a battery eliminator kit like this (get the right one for your device, be careful!) and now instead of a bunch of AA/AAA powered devices you have a bunch of USB powered devices. Get a multi-port USB charger, plug it into a smart plug, and you’re golden.
