Why Does My Smart Plug Blink Blue Rapidly After Rain?
After a rainy day, many users report their smart plugs start blinking blue rapidly and disconnect from the network. This issue is often related to moisture or signal loss – and it’s easy to fix.
Why Is Your Smart Plug Blinking Blue After Rain?
If your smart plug is blinking blue rapidly after rain, don’t worry—it usually means the device has lost connection with Wi-Fi or entered pairing mode due to moisture or electrical fluctuation.
Common Causes:
- Wi-Fi disconnection caused by power interruption
- Humidity or moisture inside the plug’s casing
- Router reboot during storm or surge
- Factory reset triggered by water or button press
How to Fix the Blinking Blue Light
1. Power Cycle the Plug
Unplug the smart plug for 30 seconds and plug it back in. Sometimes this resets the connection without needing full reconfiguration.
2. Dry the Plug Thoroughly
Leave the plug in a warm, dry room for a few hours. If moisture has entered the case, it may cause signal loss or trigger reset mode.
3. Reconnect to Wi-Fi
- Open the smart plug app (e.g., Smart Life or Tuya)
- Tap “+” and choose “Add Device”
- Follow on-screen pairing steps while the light blinks
4. Reset the Plug
If it keeps blinking and won’t reconnect, press and hold the physical button for 5–10 seconds to factory reset, then add the device again in your app.
Prevent It Next Time
- Use plugs rated for outdoor or damp environments (IP44+)
- Avoid plugging directly into exposed outlets during rain
- Consider surge protectors with moisture protection
Understanding why your smart plug blinks blue rapidly after rain helps you resolve the issue quickly and avoid future interruptions.
