It has been brought to our attention that the manufactured label on some of our boxes has been created with errors in the QR code.
What you would have to do is scan the QR code on the bulb itself.
From there, reset the bulb, like so to ensure it is in pairing mode.
From there, click this link, go to the "Add Device" section, and choose the Sengled Smart LED bulb you are trying to add to your Sengled Smart hub.
