6.1 Werkmodi
The SONOFF 4CH R3/4CH PRO R3 offers three distinct working modes to suit various automation needs:
- Inchingmodus: Turns on a device for a specified duration (0.25-4 seconds) and then automatically turns it off. This is ideal for temporary actions like corridor lighting or opening a gate for a short period.
- Interlock-modus: Ensures that only one channel is active at a time. When one channel is turned on, all other channels are automatically turned off. This is useful for controlling devices like garage doors or blinds where only one action (open/close) should be active at a time.
