Symptoms
- App shows the plug is on but the device stays off
- Device works when plugged directly into the wall
- Plug's physical button doesn't turn the device on either
Likely causes
- CommonConnected device's own power switch is offMany lamps and appliances have a physical switch that must also be on.
- CommonPlug not fully seated in the outletA loose connection can prevent power from reaching the device.
- PossibleDevice draws more power than the plug is rated forOverloading a smart plug can cause it to fail to switch or trip an internal protection.
- PossibleFailed relay inside the smart plugLike any switch, the internal relay can wear out or fail.
What to do
- Check that the device's own physical power switch, if it has one, is turned on.
- Make sure the smart plug is fully and firmly plugged into the wall outlet.
- Test the device by plugging it directly into the wall outlet to confirm the device itself works.
- Check the smart plug's wattage rating against the connected device's power draw.
- Try the plug's physical button, if it has one, to rule out an app or connectivity issue.
- If the plug's light indicates power but the outlet on it doesn't work, the plug's relay has likely failed and it needs replacement.

When to call a pro
Replace the smart plug if it's confirmed to have power but won't switch the outlet, since the internal relay isn't a practical DIY repair.
