What this light usually means
A blinking blue light on a smart plug usually means the plug is in pairing mode, connecting to Wi-Fi, or waiting to be added in an app. The exact meaning can depend on the device model, the label beside the light, and whether the light is solid, blinking, flashing, pulsing, or alternating with another color.

- Plug was recently reset
What to check first

Important warning
Do not plug high-power appliances into a smart plug unless the plug is rated for that load.
When it may be normal
This light may be normal if the device recently powered on, is pairing, is charging, is updating, is connecting, or is completing a setup step. If the light changes after a few minutes and the device works normally, it may not require further action.
When to contact support
Contact the manufacturer or a qualified professional if the light stays on after basic checks, appears with warning sounds, appears with heat or burning smells, affects a safety device, or comes back repeatedly after restarting.
