SONOFF POW Ring Smart Power Meter | POWCT

The SONOFF POWCT (POW Ring Smart Power Meter) is a powerful Wi-Fi smart energy monitoring device designed for monitoring high-current electrical circuits safely and accurately. Using a split-core CT (Current Transformer) clamp, it can measure currents up to 100A without direct contact with live wires, making installation safer and easier for both electricians and DIY users. Unlike traditional inline power meters, the POWCT uses a non-invasive clamp sensor that simply clips around the live conductor, eliminating the need to disconnect wiring or cut cables. This makes it ideal for monitoring: Main DB board supply. Geysers. Air conditioners. Solar systems. High-power appliances. Individual room circuits. Through the eWeLink app, users can monitor: Voltage. Current. Power usage. Energy consumption. Exported solar energy. Historical energy data. The device stores up to 6 months of historical energy data, which can be exported for analysis and energy management reporting. A built-in dry-contact relay output (2A rated) allows the POWCT to control an external contactor for switching heavy loads such as geysers, pumps, or industrial equipment. The unit also includes: Real-time LCD display. External antenna for improved Wi-Fi signal. Smart scene automation. Voice assistant support. Overload alert functionality. The POWCT integrates with: eWeLink. Home Assistant. SonoffLAN. Alexa. Google Assistant.
