SONOFF POWR320D POW Elite - Smart power meter switch, White

The SONOFF POWR320D POW Elite Wi-Fi Smart Power Meter Switch monitors electrical use and remotely switches a connected load. It uses Wi-Fi and Bluetooth, with control through a smartphone or tablet app. The relay is rated for up to 20 A and a maximum switching voltage of 240 V AC. The app supports remote on/off operation, while voice control works with Amazon Alexa, Google Assistant and Apple Siri. Compatibility also includes Apple Home, Google Home, SmartThings and Home Assistant. Dimming is not supported; this is an on/off load controller with metering.

Installation is on a DIN rail for indoor use, and the enclosure is flame-retardant PC V-0. A physical button provides local switching alongside app and voice controls. The switch runs from AC mains and includes overload protection for the connected circuit. App settings allow energy and overload thresholds to be configured, with notifications when a threshold is reached. Its single-channel design handles switching and metering for one controlled circuit. The relay-module format is intended for DIN-rail electrical installations rather than a conventional wall-switch position.
