Z-Wave Aeon Labs Clamp Energy Meter



The Aeon Labs Home Energy Monitor (HEM) is a energy monitor for the entire home, meant to be placed near the distribution board. It can wirelessly report immediate wattage and kWh usage to a ZWave controller.

There are two versions HEM's: one (first generation) battery or USB power operated device and the 2E version that is connection to the AC mains.

For both version you have to connect the current transformer clamps around the AC Mains of a circuit to detect energy usage for that circuit. For the 2E version you also have to connect the voltage sense lines to the same circuit.


  • Place the controller in inclusion mode
  • Press the button on the HEM
  • The LED will remain constantly lit if the inclusion was successfully.
