The device is in the category of *Sensor*, defining Device used to measure something. ![DSB28 product image](https://opensmarthouse.org/zwavedatabase/85/image/) The DSB28 supports routing. This allows the device to communicate using other routing enabled devices as intermediate routers. This device is also able to participate in the routing of data between other devices in the mesh network. ## Overview Aeon Labs Home Energy Meter is a kind of energy meter for the entire home electric power consumption. It can report immediate wattage and kWh and voltage and amperage usage of the AC mains to a Z-Wave gateway wirelessly. It can send Z-Wave REPORTS (Meter v3 Command Class) to response Z-Wave GET command at any time. HEM can also be configured as sending unsolicited reports periodically to the associated nodes (within an association group). The time interval of reports can also be configured HEM can also send report of each individual channel with corresponding current clamp via the command of “Multi Channel Command Class Encapsulation ”. To reduce the network traffic, HEM can send reports only when the loads significant change occurred(by percentage or Wattage value change, which can be configured) ### Inclusion Information 1. Connect HEM G2 to power and install the device properly (according to the Installation instruction, if necessary, please ask an electrician for help) , at beginning its LED blink slowly. 2. Let the primary controller of existing Z-Wave network into inclusion mode (If you don’t know how to do this, refer to its manual). 3. Press the Z-Wave button of HEM G2. 4. If learning success, HEM G2 LED will stop slow blink, or it will still slow blink, please repeat the process from step 2.  ### Exclusion Information 1. Make sure the HEM G2 is powered, its LED be light on steadily. 2. Let the primary controller of existing Z-Wave network into remove mode (If you don’t know how to do this, refer to its manual). 3.
