...and I want to be able to control things based on when it is turned on or off. It uses a standard 110V US outlet.
I haven't played around with current (or power) sensing outlets, but that seems like the most straightforward way to do so. Any hints/suggestions regarding what modules to use, and any pitfalls with this scheme? Or any alternative things I haven't thought of (without, of course, having to modify her new toy, of which she is very protective).
Oh, yeah... and Z-wave or Zigbee... Either one will work, not really leaning one way or the other.
I use thess Sengled smart (Zigbee) plugs to tell when my TVs are turned on....
It's not mentioned in the Amazon description, but they report power level.

I have an Elektra (1st 3 level Pinball machine ever made). A simply zigbee or z-wave outlet should be fine. Even the bumper and flipper coils aren't going to have much of a draw.
The most precise power metering device I have is Shelly 1 PM Plus, and I tested many devices. Althought wi-fi, it is very, very stable and a trustable trigger to power based automations.
