6. Operating Instructions
6.1. Remote On/Off Control
From the Smart Life/Tuya Smart app, tap on your TXCB1 device. You will see a large power button icon. Tap it to turn the connected circuit on or off remotely.
6.2. Timer Settings
The app provides various timing options:
- Timing Mode: Set specific times for the device to turn on or off (e.g., turn on living room lights at 18:00).
- Countdown Mode: Set a countdown timer after which the device will change its state (e.g., turn off bedroom lights after 20 minutes).
- Cycle Time Mode: Schedule repetitive on/off cycles (e.g., turn on for 1 hour, then off for 30 minutes, repeating daily).
6.3. Real-time Metering (TXCB1-TWM & TXCB1-VAP)
For models with metering capabilities, the app displays real-time data:
- Voltage (V): Current line voltage.
- Current (A): Current flowing through the circuit.
