7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not responding / No power | No power supply; Incorrect wiring; Circuit breaker tripped. | Check circuit breaker. Verify wiring connections (consult a qualified electrician). |
| Cannot pair with app | Incorrect WiFi network (not 2.4 GHz); Module not in pairing mode; Weak WiFi signal. | Ensure phone and module are on 2.4 GHz WiFi. Put module into pairing mode (press reset button). Move closer to router. |
| Voice control not working | Skill not enabled; Account not linked; Device not discovered; Incorrect voice command. | Enable OSRAM SMART+ skill/service. Link accounts. Discover devices in Alexa/Google Home app. Use correct device names. |
| Energy meter shows incorrect data | Temporary software glitch; Overload condition. | Restart the module by cycling power. Ensure connected load does not exceed 10A total. |
If problems persist, perform a factory reset by pressing and holding the reset button for approximately 10 seconds until the indicator light changes behavior (e.g., rapid blinking). Note that a factory reset will erase all settings and require re-pairing.
