The three different DTHs are:

  • ZigBee White Color Temperature Bulb
  • ZLL White Color Temperature Bulb
  • ZLL White Color Temperature Bulb 5000K

Supporting different color temperature ranges in either the Classic app or the new app has always been a little bit tough. First consider classic - every device that uses that a given DTH has to use the same set of tiles. The color temperature tile defines the range which is 2700-6500 for the first two DTHs listed above. That was the correct range for the first white tunable bulbs we certified, but eventually we started certifying devices that had a range of 2700-5000. Since the Classic app was still the main app in use at the time we had to make a new DTH just due to that color range.

Now we’re focusing most of our energy on the new app which uses the UI Metadata (specified by the vid). We are now able to specify different UI Metadata for devices on a fingerprint by fingerprint basis. Thus we can have devices with different color temperature ranges sharing the same DTH and still have them render correctly in the new app because each fingerprint specifies a vid that defines the correct color temperature range.

There are fingerprints going to production next Tuesday for the following Ikea devices:

  • TRADFRI bulb E27 WS clear 806lm
  • TRADFRI bulb E27 WS opal 1000lm
  • TRADFRI bulb E14 WS opal 600lm
  • TRADFRI bulb E26 WS opal 1000lm

Once those changes go to production any of those devices that are newly joined will have the correct color temperature range in the new app. However since they are all using the ZigBee White Color Temperature Bulb DTH they will show a range of 2700-6500 in the Classic app. Unfortunately if you already have one of these devices joined it will not automatically start using the correct color temperature range in the new app. You will need to delete the device and rejoin it.

I’ll admit I didn’t fully read through this thread so I’m probably missing some questions/topics that were discussed so feel to (re)ask any questions about this and I’ll do my best to respond.
