100 A Electricity Consumption Meter with Wi‑Fi SONOFF POWCT (clamp-on current probe)
























100 A Electricity Consumption Meter with Wi‑Fi SONOFF POWCT (clamp-on current probe)

Accurate measurement without interfering with wiring
The clamp-on current probe with a 0–100 A range enables safe and quick measurements without disconnecting conductors. Ideal for home distribution boards and individual circuits.

Smart reports and data export
Monitor consumption in real time, view daily, monthly, and yearly overviews, and export data for in-depth analysis and energy cost optimization.

Reliable connectivity and smart home integration
Stable 2.4 GHz Wi‑Fi with SMA antenna, app control, and support for Google Home, Amazon Alexa, and IFTTT for convenient automation.
SONOFF POWCT is a reliable smart energy meter with a clamp-on current probe (0–100 A) that does not require direct contact with live conductors. It offers detailed consumption statistics by day, month, and year, plus data export for deeper analysis. Installation in the distribution board is easy, and with Wi‑Fi IEEE 802.11 b/g/n 2.4 GHz you stay in control from anywhere.
The device is designed with an emphasis on safety and durability: it has passed tests against overvoltage, short circuit, and impact, and operates across a wide temperature range from −40 °C to 50 °C. The removable SMA antenna ensures a stable signal, and the built‑in relay (2 A) enables remote control of contactors in your home installation.
Key benefits:
- Accurate measurement up to 100 A without breaking the conductor (clamp sensor, max cable diameter 15 mm).
- Real time + 6‑month history with data export.
- Smart home: supports Google Home, Amazon Alexa, IFTTT.
- Safety: measurement category CAT II (0–100 A, 300 V max), robust PC enclosure.
