Review: Works perfectly and easy to install / setup - Excellent product and easy installation. Allows me to monitor a remote condo and keep tabs on the HVAC and power consumption. The app is well polished and provides all the information and control you would expect with this device
Review: Pro level current meter at a bargain price! - Fantastic current meter! The bonus is built in Ethernet! Small size will fit in tight spaces and easy install. Great function, except for some reason data download is not working right. There is also connection point for 1 more CT, but last I checked it is not sold separately. AND I wish there was short piece of DIN rail in box.
