The Sonoff POWR320D Elite is a smart power meter switch built for heavy-duty appliances. It handles up to 20 A or 4400 W, making it ideal for devices like air conditioners, pumps, and water heaters.

This smart switch connects via 2.4 GHz Wi-Fi and uses a reliable ESP32 chip for smooth operation. Through the eWeLink app, you can monitor voltage, current, power, and total energy usage in real-time. It also features a clear LCD display, so you can check live data directly on the device.

For added safety, you can set custom overload protection limits. If voltage, current, or power goes beyond your chosen values, the switch automatically turns off to protect your appliances.

The POWR320D supports smart features like scheduling, countdown timers, and inching mode to help automate your power usage. Even without an internet connection, it works over local LAN, so you stay in control.

Voice control is supported through Alexa and Google Assistant, and it also integrates with SmartThings and Home Assistant. This makes it easy to include in your smart home routines.

Compact in size at 98 × 54 × 31 mm, the switch fits cleanly into DIN rails or standard electrical panels. Its fire-resistant PC V-0 housing and strong terminals ensure safe, long-term performance.
