7. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Der Switch lässt sich nicht einschalten. | No power, incorrect wiring, or missing neutral wire. | Check circuit breaker. Verify Live (L) and Neutral (N) wire connections. Ensure a neutral wire is present and connected. |
| Blinds do not respond to touch or app control. | Incorrect motor wiring, switch not paired, or motor issue. | Verify motor wiring (Open, Close, Common). Ensure the switch is successfully paired with the Tuya ZigBee gateway. Check if the motor itself is functioning. |
| Cannot pair the switch with the Tuya app. | Switch not in pairing mode, gateway not connected, or Wi-Fi interference. | Press and hold any button for 15 seconds until the blue backlight flashes to enter pairing mode. Ensure your Tuya ZigBee gateway is online. Try moving closer to the gateway. |
| Sprachsteuerung funktioniert nicht. | Incorrect skill linking, device not discovered, or incorrect commands. | Ensure the 'Tuya Smart' skill is enabled and linked in your Alexa/Siri app. Discover devices again. Use correct voice commands. |
| Blinds move in the wrong direction (e.g., 'Open' closes them). | Motor 'Open' and 'Close' wires are swapped. | (Power off first!) Reverse the connections for the 'Open' and 'Close' motor wires on the switch terminals. |
