Nah. Solenoid on the sensed AC acting against a spring. Throw in a

You're making this way too difficult. You can do it with all off-the-
shelf parts. Just hardwire a fluke meter to the AC side, then use a
webcam on the sensing side connected to a laptop running computer vision
software.

Better make it a backlit meter. Oh --and a monkey to change the batteries
from time to time.
