Home Energy Management for Millions of Homes
Background
The telecom operator planned a Home Energy Management System (HEMS) for mass deployment to millions of homes. Requirements: monitor and control energy consumption, solar generation, and EV chargers; schedule HVAC equipment including boilers, heat pumps, and mini-split A/C; enable device-to-device interactions such as turning off A/C when a window opens or adjusting EV charging based on solar surplus; and provide device-level local APIs for direct cloud integration.
Project Requirements
- Monitors and controls the overall home energy consumption, solar power generation, EV chargers, etc.
- Controls and schedules the HVAC equipment, including gas boilers, electric heat pumps, and mini-split A/C units.
- Allows functional interaction between components within the system. For example, turn off split A/C when a window is opened, change the EV charging status according to the solar power generation mode, etc.
- Requires a complete set of "device-level local APIs" to directly connect to the Telco’s backend cloud server.
Our Solution
OWON delivered a complete ZigBee device suite — clamp power meters, Din rail relays, and smart plugs for energy monitoring; thermostats and IR blasters for HVAC control — plus a Smart ZigBee Hub with local networking capabilities for device-to-device interaction logic. The hub's complete local API allows direct connection to the Telco's backend server with no intermediate cloud dependency.
- Energy management devices: Provides various ZigBee devices, such as clamp power meters, Din rail relays, and smart plugs for energy monitoring, controlling, and scheduling purposes.
- HVAC control devices: Provides ZigBee thermostat and IR blasters to interface with different HVAC equipment.
- Smart ZigBee Hub: Provides a ZigBee Hub with strong local networking features that allow flexible interaction between the local Smart Devices.
- Complete API interfaces: The ZigBee hub comes with a complete local API that allows the telecommunication company to access the full functionality of OWON’s ZigBee system.
