Sonoff 4CHR3 WiFi Smart Switch with 4 Gang Control: Remote control via mobile app
This smart switch is perfect for homeowners who want to automate garage doors, roller blinds, or multiple lights without complex wiring. It goes beyond basic home security by giving you effortless control over daily routines.
Set a schedule for your porch lights to turn on at dusk, and you will see them activate from your phone before you even pull into the driveway. The three working modes let you customize operations: use self-locking for secure garage doors, interlock for synchronized devices, or inching for momentary control.
Share access with family members so everyone can manage devices together. The power-on state feature ensures your settings stay intact after outages, providing reliable automation. With Alexa compatibility and easy app control, this switch makes your smart home more connected and convenient.
