Monitor the consumption of every household appliance, electrical circuit and office device (lights, wiring, security systems, heating and cooling, etc.) separately. The device also displays the electricity produced by solar panels. The EM also includes overconsumption protection - the relay will cut the circuit immediately if it detects consumption greater than the configured power setting.
