1) Confirm the Model Number (M/N):
First, we must determine if the bulb is a Sengled Smart LED Bluetooth Mesh bulb.
Below is an example photo of where the bulb's model number (M/N) information can be found:
If the model number (M/N) of the bulb starts with a B—i.e., B11-N11, B11-N13—then it is a Sengled Smart LED Bluetooth Mesh bulb.

3) Compatible Echo Devices & Echo's Software:
Ensure you are trying to set the bulb up on a compatible Echo device.
Compatible devices include: Echo (2nd, 3rd and 4th Gen), Echo Dot (2nd, 3rd and 4th Gen), Echo Show (1st Gen), Echo Show 5/8/10, Echo Spot, Echo Input, Echo Flex, Echo Studio
Ensure your Echo device has the latest version of software. For most of the Echo devices without a screen, you can check the software version by saying, "Alexa, is your software up-to-date?"
For the Echo devices with a screen, please see the following from Amazon: https://www.amazon.com/gp/help/customer/display.html?nodeId=GYB55PBLWG8A6FJ8

4) Resetting & Re-adding:
Once you have done the first three steps, please proceed with the following to add the bulb to your Echo device:
1) Power your Echo device off—leave it off for, at least, ten seconds—and power it back on. Ensure your Echo device is online before proceeding.
2) Reset the bulb, like so: How do I reset the Sengled Smart Bluetooth Mesh LED bulb?
3) After the bulb flashes three times—pause—then blinks once, wait ten seconds; then, add it to your Echo device by saying "Alexa, discover devices".
[Conversely, you could add the bulb via the Alexa app by: opening the Alexa app, tapping on "Devices", tap the "+" at the top-right of the screen., tap "Lights", then, tap "Sengled". From here, tap "No" when asked if the bulb is a ZigBee bulb and tap "Yes" when the app asks you if it is a Bluetooth bulb. Then, tap "Next".]

5) Alexa's response:
If the Alexa devices finds the bulb, setup is complete.
But if the Alexa devices says she did not find any devices, say "Alexa, turn all lights off".
If the bulb in question turns off, then the bulb did setup and the Echo device had the common false fail issue—where an Echo device will say it did not find the bulb when it in fact did. Please, if it is not too much trouble, report this false fail to Amazon as the bulb did add but the Echo device wrongly said it did not add. Hopefully, if enough people report the issue, it can be found and solved.
Note: If the Alexa device says she failed to find the bulb and the bulb does not respond to "Alexa, turn all lights off", please contact us at Support@sengled.zendesk.com to let us know so we may assist.
