Are you certain you are getting it to enter pairing mode?
To reset your smart LED bulb:
Ensure that the bulb is on and then quickly turn the bulb off and on at least 10 times (using a light switch or power bar works best). If the reset is successful, the bulb will flash 5 times. If it does not flash 5 times, you will have to try again. For a detailed guide, please refer to this video tutorial.
Since you have a bunch of Sengled Zigbee lights, none of which are Zigbee repeaters, I am wondering if you have any other mains-powered devices that do act as Zigbee repeaters? Zigbee controllers can only handle a limited number of directly paired end devices. By adding Zigbee repeaters, that limits increases drastically. I am wondering if you may have hit the limit? How many Zigbee devices do you have?
i know this thread has sat stagnant for awhile but just wanted to put this out there,
i still cannot get these to work.
should i buy the sengled hub too?
its a bummer because the other sengled lightbulbs i have work great.
So to sum up, you only have 8 Zigbee devices total?
And only the Sengled floods are not pairing?
You are sure they are Zigbee and not Wifi or Matter or something like that? You didn't get someone's Amazon return and get the wrong item like a dumb bulb someone sent back?
What channel and power level is your Zigbee set to?
Did you try all the alternative pairing methods when prompted, I.E "bypassing 3.0 repeaters" and "exchanging keys in the clear"?
Did you try shutting down the hub and restarting, rebuilding the Zigbee network, rebooting the Zigbee radio or anything else?
they are in fact ZigBee bulbs and yes only the floods will not pair. i bought two two packs and all four have the ZigBee logo towards the base.
im on channel 25 with a power level of 8.
June 1st is when i first tried pairing these and since then there's been two updates to the hub and I've rebuilt the network a few times getting the power level just right.
I have tried pairing the bulb at the lamp 6ft away from the hub to no avail.
Same here, I see you rebooted and did hub updates, but did you ever totally power cycle?
Have you ever tried another channel, 15 would be one to try at first.
Any possible sources of Wifi interference, like you don't have your Hubitat near your Wifi router, or anything like that. Although I would think it would affect your other bulbs if that were the case...
Edit:
Have you tried pairing any other Zigbee devices, or just these one bulb that is causing issues? It might be worth buying a repeater and see if it is a certain device or every device you are attempting to pair.
