Smart switch Sonoff POWR3 White 100-240V 25A
POWR3 is a high-power smart switch designed for remote power ON/OFF and per-room energy metering. It provides sufficient output to make high-powered appliances smart and can serve as a single-room power meter by connecting all devices in that room. The device stores consumption data for up to 100 days and allows export of records in CSV format to your phone.
POWR3 combines high output capacity with energy monitoring, enabling centralized control of multiple units and detailed per-room consumption tracking. It integrates with Home Assistant via the eWeLink add-on and supports Alexa Smart Energy to display overall and individual device usage in the Alexa Energy Dashboard. The unit offers remote one-tap on/off control and synchronizes switching status across platforms. Built-in overload protection monitors voltage, current and power independently of the network and cuts power when abnormal conditions are detected.
Install POWR3 according to the manufacturer instructions and connect the appliances of a single room to the device to measure that room's combined consumption. Add POWR3 units to your eWeLink account and enable the Home Assistant add-on if you use Hass for centralized control. Link POWR3 to Alexa to display energy data in the Alexa Energy Dashboard. Use the mobile app to remotely switch power on or off, view real-time and historical consumption, and export CSV files when needed.
Use POWR3 to monitor and control groups of high-powered appliances in a single room, enable integrations (Home Assistant, Alexa) for centralized visibility, and rely on the built-in overload protection to reduce risk by automatically cutting power on detected anomalies.
