ITPEC FE Morning April 2022 — Question 73 of 80

HEMS stands for Home Energy Management System. It connects household energy devices — solar panels, appliances, and sensors — to a home network to monitor and optimize energy consumption at the household level.

Why not others:
- (b) Describes CEMS (City/Community EMS) — city-scale infrastructure (street lamps, transport), not a home

- (c) Describes telematics or connected-car IoT — vehicle condition monitoring for driving efficiency

- (d) Describes predictive maintenance IoT — factory machine monitoring to schedule part replacement

Key rule: HEMS = Home scope. If the scope is city → CEMS; vehicle → telematics; factory → predictive maintenance.
