Cisco Home Energy Management
®
The Cisco Home Energy Management Solution (HEMS) combines the Home Energy Controller (HEC), with Cisco
hosted Energy Management services to provide the utility useful tools and a managed platform for residential energy
management .
The Home Energy Management Solution (Figure 1) is designed for deployment in homes that are in the service
territory of utilities implementing programs such as consumer energy management, peak time rebates, demand
response, critical peak pricing, time-of-use pricing, microgeneration, and electric vehicle integration. The HEMS is
ideal for implementing these programs while maintaining grid reliability, energy efficiency, customer participation, and
customer satisfaction. The Home Energy Management Solution is an ideal complement to a utilities’ Smart Meter
deployment to enhance the communications with the in-home devices and to confirm pricing program utilization.
Cisco Home Energy Controller (HEC) helps residential customers monitor and control their energy use. In the home,
an optional set of Cisco compatible, tested peripherals can be wirelessly connected to the HEC in order to provide
monitoring and control of energy loads such as HVAC systems, pool pumps, water heaters, televisions, computers,
and so on.
Primary Cisco Home Energy Controller Series features:
● Engaging and easy to use, menu-driven touch screen-based, user interface
● Intuitive energy management applications for usage monitoring, budgeting, thermostat, appliance control, and
so on
● Commonly used networking communications and security
◦ Smart Energy Profile (SEP 1.0) certified ZigBee network interface for communicating with smart meters
deployed with utility advanced metering infrastructure (AMI)
◦ ERT meter reading capability provides compatibility with installed base of automated meter reading (AMR)
deployments
◦ WiFi/Ethernet network interface, which allows for communicating with cloud-based device management
system through user’s home broadband gateway and provides an alternate channel for utilities to
communicate with the HEC
◦ Secure end-to-end data communications across wired and wireless media and networking protocols
● Ability to provision and manage a home area network (HAN) in order to monitor and control a variety of in-
home devices, appliances, and energy loads

Energy Management hosted services
Another component of the Home Energy Management Solution is the hosted services to enable provisioning and
support for the devices implemented in residential deployments. The Energy Management hosted services
include:
● Provisioning and management
● Custom built/unique look and feel for the device
● Mass firmware updates to thousands of devices
● Integration with the utility backend applications and third party software (i.e. demand response analytics)
Deployment Scenario with Home Energy Management Solution
Figure 2 depicts a typical deployment scenario for utilities to implement a demand response or dynamic pricing
program. The HEC communicates with the hosted Energy Management Solution through the home broadband
connection. The HEC monitors and controls a programmable communicating thermostat (PCT) and a load control
module (LCM) through a secondary ZigBee interface. The utility backend receives usage data from the smart meter
through the AMI network. Demand Response or price events to the HEC can be sent to the HEC in two ways:
through the AMI network and the smart meter ZigBee interface or through the HEC device management system, as a
part of the Energy Software hosted services, and the broadband connection to the home. The latter option might
require some custom integration effort. In addition, a hosted consumer portal can be developed by third parties to
remotely access a subset of the HEC energy management functions on a mobile device.

Primary Business Benefits
Table 1 lists business benefits of the Home Energy Management Solution for the utility, while Table 2 lists benefits for
the energy consumer.
Table 1. Primary Business Benefits of the Home Energy Management Solution (for Utilities)
Benefits Description
Public Policy: Reduce ● Driven by government carbon policies, utilities are looking at energy conservation rather than adding generation, as
Carbon Emissions well as shifting generation from fossil fuels to renewables.
● HEM provides a means to integrate the residential consumer into the utility’s communication framework for energy
management.
Increase Grid ● Demand Response provides utilities a mechanism to shed load based on real-time conditions. DR using 1-way paging
Reliability: Demand networks is being replaced with new 2-way Advanced Meter Infrastructure, along with use of home broadband
Response Load connections.
Control ● HEM provide a mechanism for utilities to use AMI and residential broadband networks to implement a more
measurable and verifiable DR solution.
Implement Time-of- ● Most utilities charge their consumers a flat rate/kwh, in spite of them paying higher wholesale prices during peak
Use, Critical Peak consumption hours. This directly affects their bottom line as well as does nothing to help conservation during peak
Pricing, Critical Peak hours.
Rebates, Peak Time ● HEM will provide mechanisms to automate load shifting based on price of energy, without adversely affecting customer
Rebate programs satisfaction when TOU/CPP/CPR/PTR pricing is implemented by utilities.
Integrate EV, Storage ● Utilities would like to assess the overall impact of EVs, Battery Storage and Micro Generation to generation,
and Micro Generation transmission and distribution, as well as consumer behavior.
● HEM will be the platform that integrates all components in the home to provide analytics and data mining opportunities.

Table 2. Primary Business Benefits of the Home Energy Management Solution (for Consumers)
Benefits Description
Demand Response: ● Provides an easy-to-use application for utility-based pricing incentives to save energy and costs
Savings Incentives ● Offers the consumer flexibility to temporarily opt out of pricing programs
Time-of-Use and Critical ● Allows customers to set up general policies to automate energy consumption based on time of day
Peak Pricing: Manage ● Allows residential customers to manage their energy budgets effectively
Energy Budgets
Being Green: Reduce ● Allows consumers to monitor and automatically reduce their energy consumption
Carbon Footprint
Integrate Components: ● Integrates all components in the home to provide complete energy visibility and control, including electric
Vehicles, Storage, and vehicles, storage, and microgeneration
Microgeneration
Extensibility Features and Benefits
The Home Energy Controller provides the customer an extensible platform offering investment protection for
customers. Software upgrades can allow additional applications or newer versions of existing applications to be
pushed to the device from the hosted Energy Software services. Firmware upgrades for ZigBee and Wifi radios will
allow the device to communicate with newer peripheral devices or smart meters in the future.
Managing the HEC: Device Management System as a part of the hosted services
Figure 3 shows the interaction of the HEC with the different management systems
Figure 3. HEC Device Management System
The HEC is provisioned, monitored, and managed by the hosted DMS. Each utility or service provider customer has
the ability to manage their own set of devices though one or more login accounts in DMS. HEC to DMS
communication is managed by a DMS client running on the HEC. The DMS client uses a preconfigured polling
interval to send heartbeats to the DMS through an HTTPS connection. Any command or notification from the DMS to
the device is sent as the response to the heartbeat poll. Table 3 is a list of DMS features.

Utility/Third-Party Integration Mechanism with DMS
DMS has the notion of channels that service endpoints that are either publishers or subscribers. Publishers can
publish a message to a channel using a REST API (HTTP GETs/PUTs), that could be subscribed to by a client
device or group of client devices.
