If you want to check how much electricity your devices are using over a certain period of time, simply launch the app and use the appropriate function! Sonoff puts complete control in your hands.

Convenient access to information

Get convenient access to the data collected by Switch. Simply pair all your POWR3 devices with the eWeLink app and control them with your smartphone.

Effective overload protection

With the Sonoff POWR3 smart switch, you don't have to worry about safety. Advanced overload protection allows you to constantly monitor the voltage, current and power being charged in the device. If any abnormality is detected, the power will be automatically cut off immediately. This prevents damage to the switch and increases the safety of use.

Normally closed relay

Unlike other devices of this type, the POWR3 has been equipped with a normally closed (NC) relay. Thanks to this, even if there is a power outage or the switch is damaged, the circuit will not be affected. You can also set the power status yourself using the app.
