Smart plugs failing to turn on or off on schedule is usually caused by incorrect timezone settings, WiFi connectivity issues, or outdated firmware. The problem often appears after daylight saving time changes or when the plug loses its connection to your home network.
Quick Answer
- Check timezone settings in your smart plug app — must match your actual location
- Verify WiFi signal strength — weak connection causes missed schedules
- Update firmware through the app's device settings
- Confirm AM/PM settings are correct for each scheduled event
- Disable conflicting features like Away Mode that override schedules
Symptoms
- Plug turns on/off manually but ignores scheduled times
- Schedule works intermittently — sometimes triggers, sometimes doesn't
- Plug becomes unresponsive during scheduled events
- Timer shows correct time but executes at wrong hours
- Multiple schedules conflict or cancel each other out
Quick Checks
- Open your app and verify current time matches your phone's clock
- Test manual on/off control — if this fails, it's a connectivity issue
- Check if schedules work when you're home but fail when away
- Look for "offline" or weak signal indicators in the app
- Confirm the plug's LED status matches what the app displays
Step-by-Step Fix
-
Open your smart plug app and navigate to your device
- Kasa app → Select your plug → Settings
- Wyze app → Select your plug → Settings
- Alexa app → Devices → Plugs → Select your plug
-
Check timezone settings
- Kasa: Settings → Timer → Verify timezone matches your location
- Wyze: Settings → Device Info → Time Zone
- Amazon: Alexa app → Settings → Device Settings → Time Zone
-
Verify WiFi signal strength
- Look for signal strength indicator in device settings
- Should show "Good" or 3+ bars for reliable scheduling
- Move plug closer to router if signal is weak
-
Review your schedules
- Kasa: Schedule tab → Check AM/PM for each entry
- Wyze: Schedules → Ensure each schedule toggle is ON
- Amazon: Create schedules through Routines, not device settings
-
Update firmware
- Check app notifications for firmware updates
- Wyze plugs need firmware 2.0+ for reliable scheduling
- Allow 5-10 minutes for update to complete
-
Disable conflicting features
- Kasa: Turn off Away Mode if using manual schedules
- Wyze: Disable vacation mode or conflicting automations
- Amazon: Check for overlapping Routines
-
Power cycle the plug
- Unplug from wall outlet for 10 seconds
- Plug back in and wait for reconnection
If Smart Plug Schedule Still Not Working
Factory reset your plug if basic troubleshooting fails:
- Kasa plugs: Hold button for 10 seconds
- Wyze plugs: Hold button for 5 seconds
- Amazon Smart Plugs: Hold button for 12 seconds
Improve WiFi coverage with a mesh extender if signal strength remains poor. Place within 30 feet of your router for optimal performance.
Check for app-specific issues:
- Kasa users: Clear app cache and restart
- Wyze users: Sign out and back into your account
- Amazon users: Disable and re-enable the Smart Home skill
Consider upgrading to a TP-Link Kasa Smart WiFi Plug with Energy Monitoring (paid link) if your current plug consistently drops connection.

FAQ
Why does my smart plug schedule work sometimes but not others? Intermittent schedule failures indicate WiFi connectivity problems. The plug loses connection to your network and misses scheduled commands. Check signal strength and move the plug closer to your router.
Can daylight saving time affect my smart plug schedules? Yes. Many plugs don't automatically adjust for DST changes. Check your timezone settings in the app after DST transitions and update manually if needed.
Why won't my Kasa plug schedule work with Away Mode enabled? Away Mode overrides manual schedules to create random on/off patterns. Disable Away Mode in Settings → Away Mode to use your custom schedules.
Do smart plugs need internet to run schedules? Most smart plugs require internet connection to execute schedules since timing data comes from cloud servers. Local scheduling varies by brand and model.
