Sonoff POWR320D Elite Smart Power Meter Switch 20A

The POWR320D can be integrated with Home Assistant using the official eWeLink add-on. First, ensure the switch is set up in the eWeLink app. Then, in Home Assistant, install the eWeLink Smart Home integration via HACS or manually. After configuration, the switch and its power monitoring entities will appear, allowing for local control and automation without cloud dependency, provided you use the LAN control mode.

The key upgrade in the POWR320D Elite is the move from an ESP8262 to a more powerful dual-core ESP32 microcontroller, resulting in significantly faster Wi-Fi response and data processing. It also features enhanced data logging with 6 months of hourly history, a more robust V-0 flame-retardant enclosure, and direct compatibility with the Alexa Energy Dashboard for centralized energy consumption views alongside other smart devices.

Yes, the POWR320D includes configurable overload protection. Within the eWeLink app, you can set individual thresholds for maximum current (Amps), voltage (Volts), or power (Watts). If any of these parameters exceed your preset limits, the switch will automatically turn off the connected load to prevent damage or hazardous conditions. You will also receive a push notification alerting you of the event.

While basic real-time monitoring and control work via LAN, storing and accessing the full 6 months of hourly historical data requires an active internet connection and the eWeLink cloud service. Exporting this data to an Excel file is done through the eWeLink mobile app. An eWeLink Advanced plan subscription is required for features like IFTTT applets and web control, but not for core logging.
