-====== HEMS Introduction ======
-Home Energy Management System (HEMS) is a system for:
-  * monitoring electricity flows at home (consumption, production and storage),
-  * control of key consumers,
-  * optimizing consumption in terms of reducing consumption and using cheaper energy to ensure the same comfort with lower costs.
-{{:hiq_energy:hems:flow_chart.png?direct&600|}}
-===== HEMS Controller =====
-It consists of an HEMS master controller ([[en:hiq_hw:mc-230|MC-230]]).
-<WRAP pagebreak></WRAP>
-===== Power sensors =====
-The measurement of electrical power and energy of all energy sources and main electrical consumers is provided by single-phase ([[en:hiq_hw:pm1-e-d|PM1-E-D]]) and three-phase ([[en:hiq_hw:pm3-i-d|PM3-I-D]]) power sensors which are connected directly to HEMS master controller [[en:hiq_hw:mc-230|MC-230]]. It supports:
-  * **1 grid** power sensor
-  * up to **3** sensors for local power **plants** (PV, Wind, Cogeneration, Generator, etc)
-  * up to **2** local **storage** systems (home battery)
-  * up to **4** managed **consumers** (electrical heating, electrical water heater, washing machine, tumble dryer, ...)
-===== Power relays =====
-Are used for control of managed consumers. Power relays are toggling power supply or enabling signal for the operation of the device. They are controlled directly from HEMS master controller [[en:hiq_hw:mc-230|MC-230]].
-===== Push buttons =====
-Are used for manual control of managed devices. Push buttons are directly wired to HEMS master controller [[en:hiq_hw:mc-230|MC-230]].
