5. Troubleshooting
If you encounter issues with your meross MPD100 Outdoor Smart Dimmer Plug, consider the following troubleshooting steps:
- Connectivity Issues:
- Ensure your smart device has a stable 2.4 GHz Wi-Fi and internet connection.
- Access your router settings and assign a static IP address to the smart device.
- Change and set a fixed 2.4GHz WiFi channel (preferably 1, 6, or 11) on your router to avoid congestion and interference.
- If your router has too many connected devices, connect some to another router or reduce the number of active devices.
- Disable “Fast Roaming” on your router’s setting page if applicable.
- Dimmable Function Not Working: Ensure that the lights connected to the dimmer plug are explicitly dimmable. Non-dimmable lights will not function correctly with the dimming feature.
- Overload Protection: Do not exceed the maximum power ratings for connected devices: 150W for LED & CFL bulbs, and 400W for INC (incandescent) bulbs. Overloading can damage the device or cause a fire.
