If you have Airbnb this is a must. You can control the guests’ energy consumption and more! I recommend.

  • Not Accurate
Size: 1 Pack
Don't waste your money on this. I checked the 3EM readings against a clamp meter and they weren't even close to being correct.

  • Warning! This device only measures up to 90 amps per channel, *NOT* 120 amps!!!
Size: 1 Pack
BUYER BEWARE!!! I bought this to measure power usage in my home. The advertisements claim it can measure up to 120 amps per channel but Shelly technical support states the most this can measure is 90 amps per channel.
