Wemo® Smart LED Bulb, F7C033 Troubleshooting


In using the Wemo® Smart LED Bulb, F7C033 you may encounter issues with regard to its functionality.  To troubleshoot these, follow the instructions below:
 

The Wemo App is not detecting my bulbs anymore
 
There are three things that can cause this:
  1. The bulb has completely gone out (won’t light up).
  2. The bulb lights up but the wireless portion has gone out (can’t connect to the Wemo Link).
  3. The bulb has unpaired from the Wemo Link.
Solution:

First, make sure the bulb will light up.
  1. Try turning it ON manually by the light or lamp switch that it is plugged into.
  2. If it doesn’t work, move it to a different lamp or light socket and try again.
If the bulb doesn’t turn ON manually and you have done the instructions listed above, this means the bulb has gone out and is eligible for Return Merchandise Authorization (RMA).
 
If the bulb lights up: 
  1. Reset your device.  To do this, click here.
  2. Pair them back with the Wemo Link.
  3. If you are unable to pair them try restoring the Wemo Link, set it back up and pair the bulbs again.  For instructions, click here.
​If one or more of the bulbs do not pair, there could be an issue with the ZigBee radios and the bulbs will be eligible for RMA.  

If the bulbs work fine locally but cannot be seen remotely, you can try a reset procedure on the bulbs and the Wemo Link to try to get them to register with the cloud again. 
 
NOTE:  If they still do not show remotely after the restore, please call us for technical support at 1-800-223-5546.
 


The Wemo App shows a spinning orange circle and is slow to turn ON/OFF or change the brightness when I try to control the bulb

The Wemo Link behaves differently from other Wemo products during setup and resets.  The Wemo Link has two radios, namely a Wi-Fi Radio and a ZigBee Radio.  It takes a little longer for the Wemo Link to ready itself when it is first plugged in or rebooted.

Solution:
 
The Wemo Link also acts as a relay for commands between the bulbs and the app unlike Wemo devices where the app sends commands directly to the Wemo.  This slight delay might be noticeable in the way the app reacts to the current state of the Wemo device.  This is normal.

 

The Wemo Link is taking a long time to become ready after rebooting/resetting

Solution:

When resetting a Wemo Link, it takes about 90 seconds for the status light to turn green, showing that it has rebooted and is connecting back to the Wi-Fi.  After that, it takes up to 3 minutes and 30 seconds to have both radios up and ready for usage.
 

My LED bulbs take a long time to show the correct status

Solution:
 
When doing a discovery, the Wemo App sends out its discovery request.  After that, the Wemo Link will find the bulbs to get their current status and then report back to the app.  The user will see this as the app refreshes the device list when the Wemo Link connects to the bulbs.  The Wemo Link will respond by showing the bulbs it controls and their last known status (ON or OFF).
 
You may also see slowness when controlling the bulbs initially as the app gathers the current status of the bulbs.
 
If the Smart LED bulbs are not showing the correct status, try a manual refresh.  Tap the refresh button in the corner and allow up to 30 seconds to display the correct status before tapping the button again.
