Important safety information.

Please read this and other device guides carefully. Failure to follow the recommendations set forth by Aeotec Limited may be dangerous or cause a violation of the law. The manufacturer, importer, distributor, and / or reseller will not be held responsible for any loss or damage resulting from not following any instructions in this guide or in other materials.

Only a licensed electrician with knowledge and understanding of electrical systems and safety should complete the installation.

Home Energy Meter Gen5’s current per clamp can not exceed 60, 100 or 200 amps based on the version you have. Refer to product's label or packaging for specific amperage information.

It is highly recommended that Home Energy Meter Gen5 be installed either indoors or in a sheltered location. It is, however, IP44 rated and can be installed accordingly.

Keep product away from open flames and extreme heat. Avoid direct sun light or heat exposure. 

Quick start.

The installation of your Home Energy Meter has two major parts: the installation of  it into your home’s main circuit box and the syncing of it to your Z-Wave network. What follows are the instructions for both parts. Please note that only a licensed electrician, with knowledge and understanding of electrical systems and electrical safety, should perform the electrical installation of your meter into your home’s circuit box. The syncing of your Home Energy Meter with your Z-Wave network can be performed by you.

Installing the meter into a circuit box.

Important: Only a licensed electrician should perform these steps.

Important: The circuit box's main breaker should be turned off to perform these installation steps. 

The following diagrams highlight how the Home Energy Meter should be installed  dependent on the region you are in; 

In the United States, it is always a 2-phase installation;

Wiring your Home Energy Meter.

To perform the electrical installation for your Home Energy Meter (HEM), utilize the  previous images to determine the phase version of the HEM and to also illustrate the following steps 3 through 7. 

1. Turn off the home’s main electricity breaker and open the main circuit box panel.

2. Connect each clamp to the HEM using the clamp connector and screw them tight.

3. Clip the clamps of the HEM around the incoming electricity cables that connect to the  main circuit breaker. 

4. Connect AC Wire to the meter using the AC Wire Connector.

5. Insert the HEM’s neutral AC Wire into the main circuit breaker’s neutral bus terminal.

6. Insert the HEM’s live AC Wire into the main circuit breaker’s live terminal.

7. Replace the main circuit box panel.

8. Turn the main breaker back on.

It is now time to permanently affix the Home Energy Meter to a surface.  Within each meter is a low-frequency radio antenna that’s used for wireless communication. This must be taken into consideration when selecting a final  location for the meter. Thick concrete walls, metals, or motor devices will affect the signal strength of the controller and the meter.  

If the home’s circuit box is made of a metal, it is recommended that the Main Body of the meter be installed outside of the circuit box. Placing the meter inside the circuit box could degrade the quality of the radio signal and negatively impact its wireless range. To assist with such an installation, each meter is weatherized to the IP44 international standard. This makes it resistant to rain and snow when installed vertically. 

To mount or place the Home Energy Meter (HEM).

1. Remove the backing plate from the back of the HEM.

2. Affix the plate to the selected wall space using the provided screws. The plate should  be installed vertically and aligned so that the wires of the HEM are at the bottom. 

3. Attach the HEM to the backing plate.

Linking your meter to an existing Z-Wave network.

The electrical installation of your Home Energy Meter (HEM) is now complete. You  must now wirelessly link it to your Z-Wave network. 

1. Put your primary Z-Wave controller, usually a gateway or hub, into inclusion mode. If  you are not sure how to do this, please refer to your controller’s user manual. 

2. Press the Action Button on your HEM. If it has been successfully linked to your  network, its LED will remain illuminated. If the linking was unsuccessful, your HEM’s LED will continue to blink. 

The installation of your Home Energy Meter is now complete. The next step is to set up your Home Energy Meter within the interface of your primary Z-Wave controller. This will allow you to visualize and utilize the energy consumption data that your meter collects. 

Your Home Energy Meter can report wattage energy usage or KWH energy usage  to your primary controller. As each controller is different, please refer to your controller’s user manual for further information on monitoring and visualizing this data. The  Z-Wave commands supporting energy monitoring are the Meter Command Classes.

SmartThings pair steps.

Connect Home Energy Meter Gen5 to SmartThings using SmartThings' Connect app, follow the dedicated instructions available at that link.

Advanced functions.

Removing your meter from a Z-Wave network.

Your Home Energy Meter (HEM) can be removed from your Z-Wave network at  any time. You'll need to use your Z-Wave network’s primary to do this. 

1. Put your main controller into its device removal mode. If you are unsure how to do  this, please refer to your controller’s user manual. 

2. Press the Action Button on your HEM. If it has been successfully removed from your  network, its LED will blink. If the removal was unsuccessful, its LED will be solid and it will be then repeated again.

Manually resetting your Home Energy Meter.

Your Home Energy Meter can be reset to default factory settings with ease.

1. Press and hold the Action Button for 10 seconds.

2. If successful, the LED on the HEM should begin to blink slowly.

Associating your Home Energy Meter to Report Automatically.

Your Home Energy Meter can send Wattage and KWH usage reports to  associated devices. To enable this, please refer to your controller’s manual on how to configure settings on Z-Wave devices linked to your controller. Initially, the meter is set up to report Watt and KWH reports. 

Some gateways/controllers will automatically configure devices enabling you to  take full advantage of the Home Energy Meter’s features. Others may not perform any automatic configuration. In such a case you can choose to manually configure your meter to output the data that you wish to view. 

Setting automatic report flags. 

Parameter 101-103 [4 byte dec] can be configured through your gateway in case  that the default settings of your meter are not what you desire.
