High Power Smart Switch for Power ON/OFF

POWR3 has the highest output power to make your high-powered devices smart, or as a single room-meter to measure power consumption.

Power Metering for Per Room

The POWR3 is powerful enough to act as a smart meter for a single room, connecting all the appliances in the room to the POWR3 and the power consumption of each room is counted individually. Moreover, POWR3 will keep the consumption data for 100 days, which can be exported to CSV on your phone.

Add to Home Assistant Be Clear at A Glance

Multiple POWR3 can be controlled centrally, and the metadata and power consumption can be displayed on Hass through eWeLink add-on.

Join to Alexa Energy Dashboard to Track and Save on Energy Usage

POWR3 supports Alexa smart energy, which is dedicated to better help you save energy usage. You can centrally view the overall or individual device energy consumption in the dashboard.

* POWR3 is expected to access the Alexa Energy Dashboard for accurate power consumption in August 2021, during which you can manually enter the power of your loads to get the estimated power consumption.

Cut Off Power
Wherever You Are

Worry about the safety of household appliances during a long trip? Cutting off the power can ensure the safety of your appliances and save on hidden electricity bills! POWR3 supports one-tap switch on/off remotely and synchronizes the switching status.

Measuring Your Devices' Power Consumption From Now

1 min, 10 mins, 100 mins, start or stop the power metering whenever you want. Remote control and view the data via your phone without any restriction of the environment!

Keeping Your Electricity Safe At All Times

Overload protection will not be affected by the network to monitor the voltage, current and power of loads at all times. Once an abnormality was detected, the power will be cut off to avoid device damage and danger.

Installation Schematic

* Make sure POWR3 be connected to the back of the air switch, instead of the grid directly.

Normally Closed Relay

POWR3’s relay is normally closed, which means the relay remains closed when there is no power applying or the device is damaged. Even if POWR3 is damaged, the circuit is not affected. Other products’ relays are normally open. Of course, the power-on status can be set on, off, or hold through the APP.
