Älykäs sähkömittarikytkin Sonoff POWR320D WLAN-energiaseurannalla ja kaukosäädöllä

Smart power meter switch Sonoff POWR320D allows remote control and energy monitoring of connected appliances. The device measures accumulated and real-time power consumption, displays data on a built-in LCD, and supports local LAN operation as well as remote control through the eWeLink app. It also offers overload protection and a maximum load current of 20A for resistive loads.

Advantages

The Sonoff POWR320D provides scheduled control with a built-in timer and an inching mode to automatically turn appliances off after a set interval. It stores up to six months of consumption data that can be exported, supports voice control via Google Assistant and Amazon Alexa, and is compatible with IFTTT and the Alexa Energy Dashboard. The enclosure is made of PC V0 material for improved fire resistance, and the relay includes overload protection that cuts power when preset current limits are reached.

How to use

Install the Sonoff POWR320D inline with the appliance according to the supplied instruction manual and local electrical regulations. Connect the device to a 100–240V power source and pair it with the eWeLink app over 2.4 GHz Wi‑Fi or use LAN support for local control. Use the app or voice assistant to set schedules, view real‑time and historical consumption, enable inching mode or configure overload thresholds. Export stored data from the app or the desktop add‑on for further analysis when needed.

Recommendations

Use the Sonoff POWR320D with appliances whose inrush and running currents are within the specified limits; verify that resistive loads do not exceed 20A. Follow the installation instructions and local safety rules. For reliable Wi‑Fi control, connect via a 2.4 GHz network; use LAN mode where Wi‑Fi is unavailable. Regularly export or back up consumption data if long‑term records are required.
