Sengled Bulbs not connecting

Hi all, new to the forum but I’ve had the 2018 hub for a while - only had 2 water sensors connected but now I’m trying to expand my devices.

I got 2 Sengled multicolor BR30 bulbs, but I can’t seem to get them connected. Some of the steps I’ve taken already are:

  • Scanned the QR codes on the box/bulbs but I just get a message in the ST app saying “Couldn’t verify QR code”
  • Retry without scanning QR code, after a few minutes I get a message saying “It looks like we couldn’t connect. Try again or reset the device.”
  • Close out the app, reset the bulbs, and immediately try to connect again as soon as they power back on again but still can’t connect.

My hub is in the same room as the bulbs so I can’t really think of any reason that it wouldn’t be able to find them when the water sensors are in the basement and connect with the hub with no problem. If anyone has any suggestions for getting over this problem I’d love it so I don’t have to return these or buy the Sengled hub as I plan on adding a lot of smart bulbs pretty soon and the price point for these seems to be the most reasonable.

Thanks!

Hey, thanks for replying. I’ve got the v3/2018 hub.

I do have some networking equipment in the room (router/etc), but didn’t think it would be interfering since other devices in the house connect fine. I can try moving the bulbs/hub to another room to at least test that it’s not interference preventing the connection.

I have a couple of Sengled Element Touch bulbs.

To connect them I think I

  1. In the app, tap “+”, Device, Scan Nearby
  2. Power on the bulb

After 15 or 20 seconds it is recognized by both the SmartThings app and Alexa.

Sengled have also become tricky to fully reset. You may think they reset, but they only partially do. Anymore, I reset twice and only by putting them into a lamp connected to a power strip I can quickly toggle. A regular light switch may not be fast enough.

Ignore the QR codes, they never work right. As mentioned above, connect the generic way. I had 12 of these bulbs in my last house and they’re great and stable after connected.

Same issue here. I have a Sengled light strips and can’t get SmartThings to recognize it. I try to add the Device by Brand. Under the Sengland lighting option you can add Sengled, Singled Smart LED ZigBee and you can find a Sengled Wifi bulb and pick the exact product - I’ve tried each option and it fails every single time.

I’ll add in that the lights have been found by the Sengled App and Alexa. I’ve also reset the lights, my SmartThings Hub and rebooted my router all a few times.

Hoping someone out there has the magical answer.

Thanks for the tip on them not fully resetting… that seems to be the problem because I’ve tried changing the cadence of turning the bulbs off/on and finally got 3/4 (got another pair just to confirm the original 2 I had weren’t just defective) to connect (plus I grabbed a sengled hub and that wasn’t even finding them).

Still working on the final bulb but at least I know they do connect and work when I can actually get them to fully reset.

My 3 Sengled bulbs take turns to lose connection. I have to turn them off and on a few times before they’re recognised again. It’s annoying.

Do you have any other bulbs in use besides Sengled for Zigbee? If you have any that are repeaters, this can happen. Sengled are end devices and don’t repeat.

Many Zigbee bulbs listed as ZLL are known to be terrible repeaters and can cause chaos in your mesh.

I can’t get Alexa Dot 4th gen to recognize the Sengled bulb in a lamp. Or CE plugs for that matter.
Any suggestions?

If you’ve got it added to SmartThings, run a discovery within the Alexa app. If that doesn’t work, unlink and relink the skill through the Alexa app.

I just got two of the multicolor LED bulbs as well and I can’t for the life of me get them to pair. Tried rebooting hub, resetting bulbs in various lamps using various switches. It’s a giant PITA and super annoying. My white Sengled bulbs I’ve always been able to pair easily with no issues.

I know this is an old thread but just went through Sengled issues. In my case, resetting the bulb and then using scan nearby worked. 10x on off to reset. Bulb will cycle through colors (rgb?) on the next power on if successfully reset.

I find renaming the bulbs (like adding “1” to the end) can reconnect them. Then revert to the original name.

I got one of the new Sengled bulbs that has “Amazon Echo device required”. It was a deal with Amazon. Note that it is Bluetooth. I connected it to the Alexa using the “simple setup” and then I could get SmartThings to see it and now have it working in WebCoRE. I think the above bulbs were Zigbee or WiFi but if you get a new bulb you might get this type. I did not and do not plan on getting any Sengled app to get this to work.

This is how I got the ZigBee Sengled bulbs to pair with the SmartThings hub. I have Sengled bulb model number E11-N1EA. This procedure worked for me:

  1. Install the bulb in a fixture with a standard ON/OFF toggle switch or a power strip
  2. SmartThings hub powered on.
  3. Phone (android) running SmartThings app.
  4. SmartThings hub “Secure mode” is “Off”.
  5. In SmartThings app, click on “+” and add a device.
  6. Scroll until find Sengled and choose it.
  7. Select “Lighting”
  8. Select “Sengled Smart LED Zigbee”
  9. If Bluetooth is not running the on phone the app will insist on that you turn it on even though this is a Zigbee device. You must enable Bluetooth for now.
  10. The screen will say “Let’s get started with your Sengled Smart LED Zigbee”. Click on “Start”.
  11. The app next asks you to scan the barcode on the device. It’s a waste of time. Tried it many times and it never worked. Click on “Skip this step”.
  12. Now the app says “Preparing” at the top and the bottom shows instructions on how to get to the screen we are currently on (useless!). There are little dots moving in the near the preparing are the only indication that it is doing anything.
  13. Turn the bulb on and off (a cycle) AT LEAST 10 times, approximately one cycle per second, ending on the ON position. The bulb should flash a few times. If it only flashes white, it is not in pairing mode (no idea what mode it is in).

If it only flashes white, do the 10 cycles again, and again, until it flashes colors as part of the sequence. It didn’t take more than 3 cycles for each of the two bulbs I have.
14. Within a minute, the app should say that it has paired with the bulb.

I’ve been banging my head against this for a few hours. Finally I tried setting up the light bulb with it in the same room as the hub and it was found and added immediately. Then I moved the bulb to a bedroom downstairs and it wouldn’t connect.

So either I investigate zigbee repeaters or just buy WiFi versions of the bulbs.

Good luck!

So, I am having the same (perceived) problem. I may have made the mistake of removing the Sengled bulb from Smartthings without putting the hub into exclusion mode. I have since reset the bulb (on-off 5 times and the bulb flashes twice) many times while the app was in “scan for nearby devices” mode as well as before putting into scan mode. I have tried scanning the QR code but always get an error when it finally is able to read the blurry image…

I have also learned that if you turn it on and off too many times/too quickly, it starts flashing and won’t stop for several minutes(!)

Any suggestions would be most welcome

Sengled Bulbs are ZigBee devices and don’t require exclusion. Exclusion is only for Z-wave devices.

Quickly turning the bulb on and off put it into pairing mode. That is why it was blinking.

Exclusion mode is for Z-wave devices. Sengled bulbs, at least the ones I know of, are ZigBee. So no issue there.

As long as the IDE still is working, you might check there to see if there device is still listed. There have been some recent reports of deleted devices still appearing in the IDE. If it’s there, use the IDE to delete it.

You can force your ZigBee devices to rebuild their mesh by powering off your SmartThings hub for 20 minutes. That might clear up anything stray.

I have put the bulb into paring mode (flashing light) and activated the app to look for new devices. The bulb then flashes a couple of times as if it became paired, but the bulb never appears in the app (either in list of devices in a room or discovered devices.)

I have tried to rebuild the network as well, but that doesn’t seem to do anything
