Sonoff POWR3 High Power Wi-Fi Smart Switch w/ Energy Monitoring

Description

The Sonoff POWR3 is a robust, Wi-Fi-enabled smart switch engineered for high-power residential and light commercial applications. It integrates a reliable relay, a precise power metering IC, and an ESP8266-based Wi-Fi module onto a single board housed in a V0-rated flame-retardant PC enclosure. This architecture enables secure 2.4GHz IEEE 802.11 b/g/n connectivity for remote management via the eWeLink ecosystem while continuously monitoring voltage, current, and power factor.

Designed for 100-240V AC input and output, the POWR3 operates within a -10°C to 40°C temperature range, making it suitable for installation in electrical panels or behind outlets. Its core benefit lies in combining remote switching capability with detailed energy analytics, allowing users not only to control heavy loads like HVAC units or water pumps but also to identify and reduce wasteful consumption patterns through actionable data provided in the app.
