Simply connect all the equipment in the room to it – the power consumption of each of them will be counted independently. What’s more, POWR3 stores the collected data for 100 days – if you want, you can also export it to a CSV file and save it to your phone.

Turn devices on and off with one click from anywhere

Have you gone on a long trip and are worried about the security of your devices? Not sure if you forgot to turn off any of them? No problem! The POWR3 switch allows you to disconnect the power anywhere, anytime – just a few clicks on the app! This way you will take care of the safety of your equipment and avoid excessively high electricity bills. The product supports remote switching on/off of devices and synchronizes their statuses.

Use the energy metering function whenever you want

You decide at what point POWR3 should start or stop measuring energy consumption. A minute, 10 minutes, or maybe 2 hours? If you want to check how much electricity your devices are consuming during a certain time interval, just launch the app and use the corresponding function! Sonoff puts total control in your hands.

Convenient access to information

Gain convenient access to the data collected by the switch. Simply pair all your POWR3 with the eWeLink app to control it from your smartphone. You can also install the corresponding add-on on your laptop. This way, you can, for example, check which devices are on or read the stored data on your home’s electricity consumption.

Possibility of voice control

The relay is compatible with platforms and smart assistants such as Google Assistant, Samsung SmartThings, Amazon Alexa and Yandex Alice. So you can conveniently control connected devices with simple voice commands. You don’t even have to get up from your comfortable chair or reach for your phone! The product is also compatible with Alexa Energy Dashboard software, which makes it easy for users to save energy.

Effective overload protection

Using the Sonoff POWR3 smart switch, you don’t have to worry about safety. Advanced overload protection enables uninterrupted monitoring of the device’s charging voltage, amperage and power. If any abnormality is detected, the power supply will be automatically cut off immediately. This avoids damage to the switch and increases the safety of use.

Normally closed relay contacts

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