SONOFF 4CHR3 & 4CHPROR3: The Ultimate 4-Zone Smart Controller
The 4CHR3 series is designed for those who want professional-grade control. Instead of installing multiple individual switches, these 4-Gang units allow you to manage four different appliances or light zones from a single, central device.
What’s New?
Unlike older versions where you had to mess with physical switches inside the box, the new R3 series lets you change how the switch behaves directly from the eWeLink App.
One Switch, Three Smart Ways to Work:
-
Independent Control (Self-Locking): Turn 4 different lights or appliances on and off separately.
-
Safety Lock (Interlock): Perfect for motors or curtains! When you turn one channel on, the others automatically turn off. This ensures only one direction (like “Open”) is active at a time.
-
Auto-Off (Inching): Need a gate to open and then close automatically? Set a timer (from 0.5s up to an hour) so the device turns itself off after you trigger it.
