I have added two Sengled Element Plus bulbs to my HE. I can control on, off, flash, lever but I am unable to change the CT. I have 14 of these bulbs already installed that are working correctly. I have changed to the driver to Sengled Element plus and Advanced Zigbee CT and Generic Zigbee and none will let me change it . I press configure after changing the driver.
There are no errors in the logs.
Also adding these bulbs or changing any of my many sengled bulbs to sengled drivers makes them no longer function.
Yes, I have deleted and factory reset and repaired to HE a couple times. I even paired them to a sengled hub just to make sure they were not defective. i can fully change the color temp on the sengled hub.
14 - Sengled Element Color Plus A19 using Advanced Zigbee RGBW Bulb driver
7 - Sengled Element Color Plus BR30 using Advanced Zigbee RGBW Bulb driver
15 - Sengled Element Plus A19 using Advanced Zigbee CT Bulb driver
6 - Sengled Element Classic A19 using Advanced Zigbee Bulb driver
All the lights above work fine.
Adding two more Sengled Element Plus A19 bulbs that came with a Sengled hub work but color temp cannot be adjusted.
I’m having the exact same problem. I have taken the same steps you have I deleted & re-added the bulb. I changed from the generic driver to the Sengled driver as I couldn’t get the bulb to turn off with the generic driver. When I switch to the Sengled driver I can turn it on and off, but can’t change the CT.
I noticed the details were vastly different between the generic and Sengled drivers
Here’s the generic driver’s details:
When you click the Firmware Update for a zigbee device (from its own Device page), next go to the Logs page. That'll open to current/live logs, so you can click to Past logs and you should see a yay/nay acknowledgement of the firmware request.
If a f/w update is available, you should then be able to monitor its progress on the current/live logs page -- it may take a few minutes to complete.
Got the 4 pack of the same Element Plus bulbs today and all 4 paired up and work perfectly including color temperature. Not sure why the two that came with a Sengled Hub would not do color temperature but everything else worked.
