5. Operating Instructions
5.1 App Control (Smart Life / Tuya Smart)
After successful pairing, you can control the relay module using the Smart Life or Tuya Smart App.
- Remote ON/OFF: Tap the respective switch icons in the app to turn connected appliances on or off.
- Independent Control: Each channel (gang) can be controlled individually.
- Timing: Set countdown timers, single schedules, or recurring schedules to automate appliance operation.
- Working Modes: The app allows you to switch between three working modes:
- Interlock Mode: When one relay is turned on, all other relays in the group are automatically turned off.
- Self-locking Mode: Each relay operates independently; turning one on or off does not affect others.
