This is a 2-gang smart relay-switch from Sonoff-compatible SmartWise brand, ideal solution for remote control of motorized gates, garage doors, irrigation systems, or other electric devices/circuits. This smart device is compatible with the eWeLink smartphone app managing Sonoff and SmartWise products.

This is a product version featuring not just WiFi but RF receiver chips, so that the smart relay can also be controlled by Sonoff RF remote controllers and SmartWise RF wall switches. This version also has a plastic protective case.

The WiFi smart relay needs a 7V-32V AC/DC power supply, (but not compatible with 5V DC microUSB). Any connected circuits operate independently from the relay’s power supply, the relay supports 90-250V/10A alternate current connected to COM input or manages 0-30V/10A direct current in NO or NC mode. The smart device manages volt-free dry-contact switching too.

The smart relay is remotely controllable via Internet and iOS (Apple) or Android smartphone App, and you can set scheduled turning ON / OFF. Share remote control in the App with your family.

Supports momentary switch mode, closes or breaks the connected circuits after 1 sec. Ideal solution for remote control of electric gates or PC power adapters. 

It is also ideal for engine-control, because the relay supports “interlock” mode, where switching one of the circuits turns the other circuits automatically off, so you may also use it for roller shutters and other 2-way motors.
