Edit: There are a host of reasons people have pointed out on why NOT to use Peanuts. Turns out that can wreck havoc on your zigbee network in some cases. I'd suggest going for something else, I'm starting to replace mine with the ST outlet which I'm liking, and still have 1 peanut running that seems fine.
Many people in the community highly recommended the peanuts Zigbee outlets, I bought two of these and love them so far as just dumb outlets I can turn off and on.
With newer firmware they can do power reporting, but I don't have the hardward to upgrade them and the ones I recently got have older hardward.
