## Long description

Sonoff POW R3 is a Wi‑Fi smart power metering switch designed for installation in household or light commercial electrical circuits. It supports 230VAC mains and power monitoring up to 5500W, enabling real‑time energy measurement, remote on/off control, and integration into automation scenes via the mobile app. The device collects consumption data, detects abnormal power draw and can be used to implement overload protection and scheduled switching for appliances and circuits.
Advantages
The Sonoff POW R3 combines accurate power metering with relay switching in a compact DIN-rail or in-line mountable unit. It provides live voltage, current and power readings over Wi‑Fi without the need for an external energy meter. Remote control and scheduling are supported through the companion app, while local switching preserves basic functionality during temporary network outages. Built to work on standard 230VAC supplies, the device can handle resistive and many inductive loads up to a combined power limit of 5500W.
Suitable for
 Monitoring and controlling household appliances (water heaters, electric ovens, heaters)
 Tracking energy consumption of circuits or single devices for cost allocation
 Overload detection and automatic shutdown to protect wiring and equipment
 Integration into smart home automation scenes and schedules
Key specifications
 Supply voltage: 230VAC
 Maximum controllable power: up to 5500W
 Connectivity: Wi‑Fi for remote monitoring and control
 Measurements: real-time voltage, current and power readings
 Control: relay on/off switching with scheduling and automation support

How to use
Install the Sonoff POW R3 into the circuit following applicable electrical codes and safety practices; connection requires line and load wiring on a 230VAC supply and suitable protective devices (fuses or breakers) upstream. After wiring, power the unit and follow the manufacturer's app pairing procedure to add the device to the Wi‑Fi network. Use the app to view live measurements, configure schedules, set thresholds for overload detection, and create automation scenes with other smart devices. Local manual switching remains available on the unit when network access is interrupted.
Usage recommendations
Use the device within its rated voltage and power limits and ensure proper upstream circuit protection. For inductive loads such as motors or compressors, verify startup current does not exceed the relay's capabilities. Place the unit in a dry, ventilated enclosure and follow local regulations for permanent electrical installations.
