WeMo LED Lighting Starter Set - Bulbs Not Detected

Context:

WeMo Lighting Starter Set
iOS Wemo App

Problem:

 The WeMo Lighting Starter Set comes with two bulbs, but they cannot be detected.  It is one of the most frustrating things!  I've lost hours trying to get them to work.  Stupid thing!  I've tried resetting the link, reinstalling the app, resetting the bulbs so many times, but the bulbs do not get detected during scan.  The link somehow does not see them.

Solution:

After a lot of tries, I have finally been able to detect them and add them.  Victory at last!

Ok, I'm not sure if this will help you, but you can try my steps:

1. Reset the link
1. Press and hold the little reset button on the link for about 5 seconds while plugging it in (same as instructions written on it) to restore to factory settings.
2.  You will first see the amber light blinking.  This may take some time, and then, you will see the light blinks amber and green alternately.  When you see this, it is ready to be hooked up.
3. Go WiFi into Settings (iPhone) and connect to the Wemo link.  You should see an SSID something .Link.
4. Connect to it
5. Open Wemo app.  It should say that you are connected to the link and that it's trying to open a connection.
6. It will try to connect to your WiFi network next.
7. If all successful, it will go into the scanning mode to detect the bulbs.
8. If your bulbs are found, great!  (For me, nothing is found!)
2. If your bulbs are not detected, follow the steps below to reset the bulbs.  You can try one bulb, and then add another later.  Note that you do not have to reset the link every time you add a bulb.  You can go to the "Add a device" in the settings of the WeMo App to scan and add new devices.
1. The instructions on the support page as listed below.  However, I followed exactly that and it DID NOT work for me.  What worked for me was that instead of 1 second as instructed in step 2, 4, 6, I did about 3 seconds for each of the steps.  If the bulb flashes, it's been reset successfully.  If it succeeds, open the WeMo app, go to add a device and scan.  If all is good, you should be able to detect the bulb.  Repeat the same process to add the other bulb.
   Step 1:
   Start with the WEMO LED Lightbulb being in the ON position.
   
   
   
   Step 2:
   Turn it OFF for one (1) second.
   
   Step 3:
   Turn it ON for 3-4 seconds.
   
   Step 4:
   Turn it OFF for one (1) second.
   
   Step 5:
   Turn it ON for 3-4 seconds.
   
   Step 6:
   Turn it OFF for one (1) second.
   
   Step 7:
   Turn it ON and leave it as it is.  After about five (5) seconds, the WEMO LED Lightbulb will flash which shows a successful reset.
