Electricity pulse counter is used to remotely monitor electricity consumption in order to control related expenses and quickly detect anomalies. You can connect it to any meter equipped with Standard output (SO). The solution is dedicated for both enterprises and households. The sensor can simultaneously work with up to three electricity meters. By default, each counted pulse represents one watt-hour (Wh). Data is presented in the form of power consumed by devices (W) in addition it is possible to generate a report with total consumption (Wh / kWh) in a selected period.

Efento NB-IoT pulse counters transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Pulse counters are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT pulse counters can be integrated with any cloud platform.
