Why Is My Wyze Plug Not Turning Off Device Completely
- Plug relay stuck
- High-wattage device welded contacts
- Firmware bug
Problem Description
Your Wyze Plug shows as off in the app but the device plugged into it still receives power — the connected device LED stays on and it continues operating. This indicates the relay inside the plug is stuck in the closed (on) position and did not physically open when the off command was sent.
Symptoms
- App says off but device has power
- LED on plugged device stays lit
- Cannot kill standby power
- Turn off command acknowledged
- Other Wyze plugs work correctly
- Manual button does same thing
Recognize these? Here's what usually causes it.
Common Causes
- Plug relay stuck
- High-wattage device welded contacts
- Firmware bug
- Overloaded plug
- Plug damaged internally
- Device drawing power from second outlet
Most fixes happen in the first 3 steps.
A plug that cannot turn off is a fire hazard. Discontinue use immediately and replace.
Step-by-Step Solution
Power Cycle the Wyze Plug Itself
Unplug the Wyze Plug from the wall outlet for 30 full seconds then plug it back in. A mechanical relay that is stuck in the closed position sometimes resets after a full power cycle removes the holding current. After plugging back in, wait 30 seconds for the plug to reconnect to WiFi, then send an off command from the Wyze app and verify the connected device loses power.
Check the Load Against the Plug Rating
The Wyze Plug is rated for 15A at 120VAC, which is 1800W maximum. High-wattage resistive loads such as space heaters, portable air conditioners, or toasters that cycle on and off can weld relay contacts over time from the inrush current on each power cycle. Check the wattage of the device that was plugged in. If it was near or above 1200W with frequent cycling, relay contact welding is the likely cause — the plug needs replacement.
Test with a Different Low-Wattage Device
Plug in a simple lamp or phone charger instead of the original device. Send an off command from the Wyze app. If the lamp turns off, the relay is working and the issue was specific to the original device drawing abnormal current. If the lamp also stays on, the relay is definitively stuck and the plug is defective. Document the test result before contacting Wyze support for warranty replacement.
Update Wyze Plug Firmware
In the Wyze app tap the plug then the gear icon then Device Info then Firmware. If an update is available install it. Certain firmware versions had bugs where the relay state in app did not match the physical relay state — the UI showed off but the relay remained on. A firmware update corrects the state synchronization between the app and physical relay without hardware replacement.
Factory Reset and Re-Pair the Plug
Press and hold the button on the side of the Wyze Plug for 10 seconds until the light flashes yellow and blue, indicating factory reset. Remove the plug from the Wyze app and re-add it as a new device. A corrupted relay state stored in firmware can persist through normal restarts but clears on factory reset. After re-pairing, test switching off and verify the connected device loses power.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Do not use smart plugs for high-wattage heating devices. Use dedicated smart switches rated for the load.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
