- Connectivity: Wi-Fi (2.4 GHz) and Bluetooth
- Highlights: Voltage, current, active and apparent power per phase, measured contactlessly via current transformers up to 63 A. Four-quadrant metering, so it also suits photovoltaics and grid feed-in. Stores up to 7 days of measurement data on the device.
