eGauge has 3 current models of meters: Core (EG4015), Core Residential (EG4115), and Pro (EG4130).


All EG4xxx models have the same integral features. They only differ by the number of CT inputs and whether there is integrated HomePlug AV (Powerline) communication.

What is integrated HomePlug?

HomePlug AV is a communication method, where a network connection can be made over the powerline the eGauge is connected to. With integrated HomePlug communication, the eGauge can communicate directly to a compatible HomePlug adapter on the same powerline, which is then connected via Ethernet to a local network. HomePlug communication should only be used in residential environments, as commercial and industrial powerlines may be an incompatible voltage and tend to have more noise and poorer quality where the HomePlug signal may not function.
