The device operates on a single-phase 100–240 V AC electrical system and can transmit measurement data for circuits rated up to 16 A and 3840 W. It measures mains voltage, current, instantaneous power, and consumed energy. It does not include a switching relay, so it cannot switch the power supply of the connected circuit.
Bidirectional energy metering separately records energy drawn from the grid and energy transferred in the opposite direction. In addition to monitoring electrical loads, the module can therefore also be used to track the production of plug-in balcony solar systems and smaller photovoltaic installations. The eWeLink system supports hourly, daily, and monthly reports, energy history, data export, and electricity cost calculations based on fixed or time-based tariffs.
The MINI-ZB1GP uses Zigbee 3.0 communication. As a permanently mains-powered Zigbee router, it can also forward the data traffic of other Zigbee devices within the mesh network. It also features a Turbo Mode that can significantly increase communication range. With a SONOFF Zigbee gateway, it can be integrated into the eWeLink system, while a compatible coordinator enables integration with Home Assistant, Zigbee2MQTT, ZHA, SmartThings, and other platforms. Available measurement data and settings depend on the gateway and integration being used.
