Introduction
The CET-HD-EMU Energy Management Unit (EMU) is a desktop controller for Combined
Energy home energy management systems.
The objective of home energy management is to reduce the average price of power being
purchased from the grid and to increase the use of solar in household appliances. Major
electrical loads and storages in the home are coordinated by the EMU with reference to
weather forecast data, energy prices and historical usage patterns in accordance with the
energy management policies provided by the Combined Energy Cloud Platform.
The EMU communicates with smart appliances and control devices within the home via
Power Line Communications (PLC) using the existing building wiring.
The EMU connects to the Internet to download weather and tariff data via either the home
network or a dedicated cellular connection. Direct connection to the local network is made by
connecting an Ethernet cable to the home router, or by joining to the home Wi-Fi via an
optional Wi-Fi USB dongle. The USB expansion port also supports a range of commodity
USB cellular modems for standalone operation.
Historical energy consumption and cost data collected by the EMU from smart appliances
and load control adapters in the home can be viewed on the Combined Energy atHome
website.
Site commissioning and configuration is performed via a web interface available through the
Combined Energy atHome web service.

Setup Guide
Requirements
Before setting up your EMU, please consider the following system requirements:
1. The EMU requires a reliable connection to the Internet to function properly.
Internet connectivity can be provided to the EMU through one of the following
methods:
➢
OPTION 1: Direct Ethernet connection to your home Internet router (using the
included blue Ethernet cable)
➢
OPTION 2: Ethernet connection to a third-party Wi-Fi extender (extender
joined to home Wi-Fi network)
➢
OPTION 3: By connecting directly to a cellular data service (note: an
additional cellular USB modem and data plan are required for this option)
2. You must have a user account set up with Combined Energy to use the EMU.
This account should have been created for you by the company that is installing your
energy management system. Your account login will be either your email address or
mobile phone number.

Installation
1. Find a suitable location for your EMU. If you are using the Ethernet connection
option, the ideal location for the EMU is close to the Internet Router and nearby to a
spare wall power outlet.
2. Plug the EMU power cable directly into a wall outlet if possible, rather than into a
power board.
The socket-outlet shall be installed near the equipment and shall be easily
accessible.
3. Follow the appropriate connection setup guide below depending on your chosen
connection method:
Connection Option 1: Wired Ethernet
Use an Ethernet cable to connect the EMU to the Internet router.

On the EMU end, plug the cable into the port marked Router:
At the router, the Ethernet cable should be plugged into one of the numbered LAN ports:
If your router does not have an Ethernet port:
● Confirm that the unit is an Internet router and not another device like an NBN box.
● Check if you have any other devices that use Ethernet in your home (e.g. laptops,
PCs), as sometimes it may not be obvious which device is the router (rather than a
modem, for example).
● Use one of the alternative connection methods.

Connection Option 2: Wi-Fi
An additional Wi-Fi extender with an Ethernet port is required for this connection option. First
join the Wi-Fi extender to your home network, following the installation instructions included
with the Wi-Fi extender. Connect the EMU Ethernet cable to the Wi-Fi extender to provide an
Internet connection to the EMU.

Connection Option 3: Cellular
A compatible USB cellular modem is required for this connection option. Please contact
Combined Energy for information on supported USB cellular modems.
1. Ensure the USB cellular modem has a SIM inserted with an active data service.
2. Plug the USB cellular modem into the Expansion port on the back of the EMU:
3. The Cloud indicator on the front panel will change to green when the EMU is
connected to the Combined Energy cloud service.
For more information on the UI light indications, please see the User Interface
section of this manual.

In some cases it may be necessary to manually reset the Powerline Communications (PLC)
network. This can be done by pressing and holding the tactile push button on the back panel
of the EMU for at least 20 seconds and releasing the button when the lights turn RED.
