How to switch a 5V led lamp? (piefed.ca)

I've got a cheap salt lamp with a LED inside and it runs on a 5V wall wart. I think it originally had a USB plug but I cut that off and connected it to an old 5V power supply.

I've never used esp32, but I've been doing some reading and it seems like an esp32-c6 will allow me to do this with ZigBee.

Does this sound reasonable? Are there other options I should consider?

You might need a transistor or relay between the esp32 and lamp, assuming the lamp draws more current than the esp32 can sink.

Easiest solution is probably a Zigbee or wifi switch for the wallwart, but that's not as elegant and a bit overkill :P
