6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting to Wi-Fi. | Incorrect Wi-Fi password, 5 GHz network, device too far from router. | Ensure correct 2.4 GHz Wi-Fi network and password. Move device closer to router. Reset device and try pairing again. |
| Light not turning on/off. | Incorrect wiring, no neutral wire, faulty light fixture. | Verify wiring according to the diagram (ensure neutral wire is connected). Check if the light fixture works with a traditional switch. Ensure power is supplied to the module. |
| Voice control not working. | Refoss account not linked, device not discovered, incorrect voice command. | Check if Refoss skill/service is enabled and linked in Alexa/Google Home app. Redo device discovery. Use correct device name in commands. |
| Energy monitoring data is inaccurate or missing. | Cloud function disabled (for remote access), temporary network issue. | If accessing remotely, ensure cloud function is enabled in the app. Local data is stored for 24 hours if cloud is off. Check network stability. |
