Home Energy Management System (HEMS) is a system for:
It consists of an advanced HEMS controller (HC-IQ-HEMS), a suitable power supply (PS-IQ), and communication interfaces for meters, and consumer management devices (CAD-232-A2-IQ, GW-WN-W and GW-ENO-IQ).
The measurement of electrical power and energy is provided by single-phase (PM1-E-D) and three-phase (PM3-I-D) meters, which are connected directly to CAD-232-A2-IQ or via a wireless bridge (BR-WN-W) to the HEMS controller.
Are used for control of managed device. Wired load managers (relays, power-relays) are toggling power supply or enabling signal for the operation of the device. They are controlled directly from HC-IQ-HEMS.
HEMS also enables the use of various wireless load management devices:
which in addition to switching, also measure the consumption of these so there is no need for additional power meter.
Are used for manual control of managed devices. Push-buttons are directly wired to HEMS controller, but also wireless push-buttons (PB-ENO) are supported.
Sensors captures additional information about controlled devices, which can help optimization of load management. Supported sensors are:
