This is a 4-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 other Sonoff products. You can use the WiFi-equipped smart relay to close or break any circuits, and turn ON / OFF any devices connected to the relay.

The WiFi smart relay needs a 5V USB or 7V-32V DC power supply. 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. 

2 and 4 channel versions are also ideal for engine-control (where 2 or more axis motion is required), because the relay supports ""interlock"" mode, where switching one of the circuits turns the other circuits automatically off.
