Hi! I found many issues surrounding light control and color conversion. I'm creating this tracker to document them and bring some attention. We may also create dedicated issues to discuss in-depth, although I feel most fixes will be easy.

---

• HA (Z2M) - input for color is displayed like an HS color wheel, but it sends XY data to mqtt
  Invalid color mode 'hs' received zigbee2mqtt#28757 (comment)
  Invalid color mode 'color_temp' received zigbee2mqtt#31320 ?

• WF - input for XY color is displayed like an HS slider

• ZHC - rgb/hex mqtt command is converted to XY, even if HS is available

• ZHC - HS command fails when not supported, without fallback to XY
  Disable enhanced hue by default & convert HS to XY, on XY-only bulbs #11840

• ZHC - enhancedHue defaults to enabled
  Disable enhanced hue by default & convert HS to XY, on XY-only bulbs #11840

• ZHC - enhancedHue allows 0-65535 precision, but mqtt input takes only 0-360

• ZH - when enhanced HS fails with unsupported cluster command, no error shows up in Z2M

• ZH - when changing Tuya attribute DND returns unsupported cluster, no error shows up in Z2M

• ZH - startUpColorTemperature = previous fails in ZH with invalid value
  startUpColorTemperature requires max of 65279 zigbee2mqtt#31452

• ZHC - incomplete implementation of Philips Hue
  philips: rewrite manuSpecificPhilips2 encode/decode, fix effects and state reporting #11655

• ZHC - incomplete definitions (many devices missing supported color modes and useful attributes)
  Improve IKEA KAJPLATS #11849

• ZHC - generated definition omits useful attributes (onOffTransition, executeIfOff...)

• ZHC - confusing unit (deciseconds) for onOffTransition... attributes
  Change _onOffTransitionTime_ unit to seconds #11854

• ZHC - enabling Z2M transition causes lights to turn on at 1% brightness from bound remotes
  Support OffWithEffect for Philips Hue & Co. #11197

• WF - startUpCurrentLevel = 255 (previous) is not displayed correctly

• WF - there is no input for MoveToLevel without OnOff (also Move/Stop, Step)

• HA - temperature slider and color wheel continuously send mqtt, spamming the network (brightness slider is ok)

@andrei-lazarov First, excellent emoji chain! 💪
Second, great idea to somewhat consolidate these related issues.

Btw. my contributions have slowed down a bit because I'm currently analyzing Z2M's workflow & organization for some academic work. I'd be happy to share my findings in the future on how we can improve collaboration without changing the welcoming character of the project. 🫶
