Luckily we can easily clear the bad data by reaching into the files of the Sengled application and here’s how:

  2. Reach into the Storage menu.
  3. From there select the Sengled application.

Many users have reported that when the bulb worked fine for a few months and then suddenly became unresponsive, they’ve found the solution.

Actually, this is exactly what you need to do but 10 consecutive times. This is not a user-made method, in fact, the bulb will indicate a successful reset by blinking 3 times.

Simply turn the OFF and ON the bulb for at least 10 times until you see the light indication.

That should make the Sengled bulb become responsive and connect to the app.
