efergy Editorial Review
The Efergy E2 Classic is a wireless display and transmitter that is designed to help users monitor their electricity usage by measuring AC power Consumption in watts and amps. It comes with two clamp-on sensors that wrap around the main service wire, which feeds both phases of the house, and a total reading for both phases is transmitted wirelessly to the display. It requires users to measure and input the incoming voltage to provide accurate results. Users can also purchase additional sensors to monitor different areas, such as their backup generator. The wireless transmitter works up to 130-230 ft within the home. However, obstructions such as thick concrete walls can reduce the transmission range. The display doesn't display the line voltage but requires the user to enter line voltage to calculate power. The Efergy E2 Classic does not come with a driver, but you can download the elink software and plug in the unit via USB into your computer, and it will install automatically. In terms of customer reviews, some users report difficulties with the accuracy of the readings and the software that accompanies the device. However, most users find the device to be easy to install, use and value the insight it offers into their power Consumption. The Efergy E2 Classic offers an affordable and straightforward solution for anyone looking to monitor their electricity usage without having to connect to a web app or cloud service.
