Works as expected. Great for monitoring my indoor garden.

Have this hooked up to my lights for the indoor garden. It works flawlessly. Although it's hard to tell the exact accuracy, It does appear to register the correct voltages and frequency (but that should be pretty standard and easy to calibrate due to u.s. power grid standards). As for the kwh (what I'm most concerned with) it seems to register the same use each day for my setup that is on a timer. So I do believe it's working as expected and helps me decide which vegetables and herbs to grow.
