Zwave/Zigbee Control of Battery Powered LED Fairylights

There’s a FAQ for that… (This is a clickable link)

How to turn anything with an on/off switch into a connected device?

For instance, I have a little battery-powered rainbow spinny light that projects patterns on the wall. I’d love to open it up and solder a few wires to a zwave/zigbee radio so I can add it to the network. What should I be looking for?
