- Wiring Diagram: Refer to the wiring diagram below for correct connections.
Image Description: This image displays the Avatto ZWSM16-W4 ZigBee smart switch module with its wiring diagram. The module is white with blue terminal blocks at the bottom. The diagram shows connections for Neutral (N), Live (L), and four output channels (L1, L2, L3, L4) for lights. On the right side, there are connections for external switches (S1, S2, S3, S4) and a common (COM) terminal. The module specifies "ZWSM16-4-Zigbee", "Voltage: AC100-240V 50/60Hz", and "Max.load: LED 4x150W 4x2.5A". A CE mark and a crossed-out wheeled bin symbol are also visible.
- Connect Wires:
- Connect the Live (L) wire from your power supply to the 'L' terminal on the module.
- Connect the Neutral (N) wire from your power supply to the 'N' terminal on the module.
- Connect the Live output wires for your lights to the 'L1', 'L2', 'L3', 'L4' terminals respectively.
- If using external physical switches, connect them to the 'S1', 'S2', 'S3', 'S4' terminals and the 'COM' terminal as shown in the diagram.
- Secure Module: Place the module securely within the electrical box.
- Restore Power: Once all connections are secure and the module is safely housed, restore power at the circuit breaker.
- Pairing with ZigBee Gateway:
- Ensure your ZigBee gateway (e.g., TUYA ZigBee Gateway) is powered on and connected to your network.
- Open the TUYA / Smart Life app on your smartphone.
- Follow the app's instructions to add a new device. The module should enter pairing mode automatically when powered on for the first time, or by pressing a reset button (if available, refer to specific product packaging for button location).
- Once detected, follow the prompts to complete the pairing process and assign the module to a room or group.
6. Operating Instructions
6.1 Using the TUYA / Smart Life App
- On/Off Control: Tap the respective switch icon in the app to turn connected lights on or off.
- Grouping: Group multiple ZWSM16-W4 modules or individual channels to control them simultaneously.
- Scheduling: Set specific times for lights to turn on or off automatically.
- Timers: Set countdown timers for lights to switch off after a set duration.
- Automation/Scenes: Create custom scenes (e.g., "Movie Night" to dim lights) or automate actions based on other smart devices (e.g., turn on lights when motion is detected).
- Device Sharing: Share control of the module with other family members through the app's sharing feature.
6.2 Voice Control
Once integrated with Google Assistant or Amazon Alexa (via the TUYA / Smart Life skill/action), you can use voice commands:
- "Alexa, turn on Living Room Light 1."
- "Hey Google, turn off Kitchen Lights."
- "Alexa, set Bedroom Light 2 to 50%." (If connected lights support dimming and the module is configured for it, though this module is primarily on/off).
7. Maintenance
- Cleaning: Ensure power is off before cleaning. Wipe the module with a soft, dry cloth. Do not use liquid cleaners or aerosols.
- Firmware Updates: Periodically check the TUYA / Smart Life app for available firmware updates to ensure optimal performance and security.
- Environmental Conditions: Avoid installing the module in areas with high humidity, extreme temperatures, or direct sunlight.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not responding / Lights not turning on. | No power to the module, incorrect wiring, module not paired, ZigBee gateway offline. | Check circuit breaker. Verify wiring according to diagram. Ensure ZigBee gateway is online and the module is paired. Try re-pairing the module. |
| Cannot pair module with app. | Module not in pairing mode, ZigBee gateway too far, interference, incorrect app procedure. | Ensure module is in pairing mode (often indicated by a blinking light). Move gateway closer. Reduce interference. Follow app's pairing instructions carefully. |
| Voice control not working. | Incorrect device name, TUYA/Smart Life skill not enabled, no internet connection, voice assistant not linked. | Verify device names in the app. Ensure TUYA/Smart Life skill is enabled in Alexa/Google Home app. Check internet connection. Relink accounts if necessary. |
| Lights flicker or do not turn off completely. | Incompatible load type (e.g., some low-power LEDs), exceeding max load. | Ensure connected lights are compatible with smart switches. Verify total load does not exceed module's specifications. Consider using a bypass capacitor if flickering persists with low-power LEDs (consult an electrician). |
