Motivation

Need for a device to interface to Smart Meter at Home and make the energy data available over Internet

– Remote Energy monitoring for a Green Home– Billing data for Utility Provider– Demand-supply response through real-time feedback to user– Control Home Electrical Appliances Remotely over Internet

Drawback of existing solutions Small display screen of Smart Meter Devices High-cost of the Gateway Equipment (mostly PC) High Energy consumption of the Gateway Equipment (need for 24x7 ON) Not easy-to-use for non computer-savvy users

Proposed System

9April 15, 2023

Solution Approach

• Use Home Television as Ubiquitous medium to display energy consumption data

• Interface to the Energy Meter through a Over-The-Top (OTT) box using USB based Zigbee / RS 485

• OTT box connected to Internet via standard Broadband

• Low-cost and Low-power main design criteria for OTT Box

• OTT box to additionally provide Infotainment functionalities like Media Player and Browser

• Simple TV Remote based UI on TV for non-computer-savvy users

• Posting of Energy Meter Data to a Internet Portal for analytics and interfacing to Utility Provider

Heart of the system – manages all modules

Data CollectorReads the energy data from smart meter at regular timing interval and pushes it to the Data management Module. Implements the MODBUS protocol to talk to the Smart Meter.

Data ManagerValidates the data received from the energy meter and store in the repository as per daily, weekly and monthly basis. Also calculates the energy consumption price based on the tariff received from the Energy Utility provider.

Utility CommunicatorUsed to upload the data to the utility portal.

Appliance ControllerUsed for controlling the different devices using Zigbee/MODBUS to switch ON/OFF the different appliances.

Benefits

• Browse consumption related information

• Track and modify home energy usage so as to reduce the amount of electricity bill.

• Remotely regulate household appliance switching in order to optimize consumption

• Pay bills online using TV based browser interface

• Obtain customized information based on historical data

• Interact with utility provider customer helpdesk using video chat feature

• Receive alerts from regarding high consumption, outage, which can help reduce billing costs as well as help plan for emergencies

18April 15, 2023

Solution Differentiators

• Low-cost OTT Box (< USD 100), hence affordable

• Low Energy consumption for OTT Box (< 3W)

• Display on Large TV Screen blended on top of Existing TV program

• Continuous Monitoring of Consumption while watching TV

• Very easy-to-use Infra-red Remote based UI

19April 15, 2023

Future Work

• Energy Data Analytics and Prediction (using on-board DSP)

• Privacy Preservation

• Demand-supply response

• Control other Smart Appliances at Home locally and from Office over Internet (true Internet-of-Things use case)

• Creation of an Intelligent Energy monitoring Portal
