Μετρητής κατανάλωσης ρεύματος Sonoff POWCT Αμπερόμετρο Wi-Fi 100 A

SONOFF POWCT electricity consumption meter with 100A current probe and Wi‑Fi connectivity provides non‑contact monitoring of home power usage. The device measures current up to 100A through a detachable current transformer (CT), connects to 2.4 GHz Wi‑Fi and allows real‑time monitoring, historical data storage and export via a mobile app for clearer insight into consumption patterns.

Advantages

SONOFF POWCT combines accurate non‑invasive current measurement with remote monitoring and compatibility with Google Home, Alexa and IFTTT. The unit stores up to six months of consumption data for analysis and export, includes a built‑in relay for remote contactor control, and uses an SMA antenna interface for stable Wi‑Fi reception. Rugged PC housing and wide operating ranges ensure reliable indoor operation.

How to use

Install the POWCT in the electrical panel and route the conductor through the CT sensor without direct contact with live conductors. Connect the transformer interface using the supplied RJ9 cable and power the unit from the panel. Configure Wi‑Fi (2.4 GHz) and link the device to the SONOFF mobile app to view real‑time consumption, access historical reports and export data. Use the built‑in relay to control contactors remotely where required, observing the relay current limit.

Recommendations

Ensure installation is performed by a qualified electrician and verify compatibility with your electrical system. Do not exceed the CT maximum cable diameter of 15 mm and respect the 100 A sensing limit. For stable remote operation, connect to a reliable 2.4 GHz Wi‑Fi network; avoid 5 GHz networks. Keep the device indoors within the specified temperature and humidity ranges.
