The Energy Meter Reader measures electricity, gas and heat usage of analog and digital energy meters. Analog meters are read by means of optical sensors that can be placed on the energymeter to monitor the rotating disc or the blinking LED. In case of a digital meter, the meter adapter can be connected to the digital meter by means of a P1 digital communication interface. The meter adapter measures the cumulative and instantaneous gas and electricity consumption and sends this information to a Z-Wave enabled display (Quby Energy Display).
