SONOFF POWCT - Smart power meter, White

The SONOFF POWCT Smart Power Meter, 100 A Wi-Fi Energy Monitor with Current Transformer is designed for circuit-level monitoring of household, room, appliance or solar electricity use. Its 100 A split-core current transformer clamps around a conductor, so the monitored wire does not need to be cut or disconnected during installation. The meter records voltage, current, power and energy consumption in real time. A built-in display shows readings at the electrical panel, and the device also measures solar energy flow. Its single-channel design is intended to monitor one circuit at a time.

The unit mounts on a DIN rail inside a residential or light-commercial electrical distribution panel and runs on 100–240 V AC mains power. Its housing is made of PC V0 flame-retardant polycarbonate. Wi-Fi operates on the 2.4 GHz band using IEEE 802.11 b/g/n, with remote access through the eWeLink app for Android and iOS. Listed smart-home compatibility includes Apple Home, Google Home, Amazon Alexa, SmartThings and Home Assistant; Matter integration is supported through compatible platforms. Typical power consumption is specified at 2 W.

• Up to six months of historical data: supports review of past energy use in eWeLink.
• Overload-related alerts: sends notifications when an overload condition is detected.
• Dry-contact relay interface: enables external load switching when paired with a suitable contactor.
• RJ9 connection: provides the interface for the current transformer.
• Smart scenes: allows the meter to be used in app-based automation.
• Bidirectional solar monitoring: tracks energy flow in both directions.
