deCONZ v2.05.76 breaks some bulbs integration with Home Assistant

[stickpin]

Hi,

It seems that after logic refactoring (https://github.com/dresden-elektronik/deconz-rest-plugin/pull/2553) Home Assistant working with some bulbs (Ikea for example) incorrectly.

It seems that Home Assistant trying to set CT but it's no longer available. Here is the home assistant log:

2020-05-23 19:31:18 ERROR (MainThread) [homeassistant.components.automation] [Test][TS] Turn On Light: Error executing script. Unexpected error for call_service at pos 1: /lights/17/state parameter, ct, not available

The issue also opened on Home Assistant side: https://github.com/home-assistant/core/issues/36044

Stange -- ive got the same bulb type and firmware of bulb here. Ive got no issues at all working that bulb. Tried all features with full functionality and response.

Just a thought - does this bulb support CT? It do support XY...

What happens if you remove the bulb from /config/.storage/core.entity_registry and let hass re-populate it automatically?

[ebaauw]

The CWS bulb doesn’t support colour temperature. Pre-v2.05.76 there was a hack to translate ct for IKEA lights into xy. This hack caused issues with the TW lights, and has been removed in v2.05.76.

Thanks @ebaauw for clarification. I will change it to XY.

Was actually not related to removing the hack, but due to more stringent checking in the API that attributes set were actually exposed. As you can see above: the /lights resource does not contain state.ct. Made an exception for IKEA, so ct can once again be set for this light.

$ ph put -v /lights/10/state '{"ct": 454}' 
{
  "ct": 454
}
$ ph get /lights/10/state
{
  "alert": "none",
  "bri": 1,
  "colormode": "xy",
  "effect": "none",
  "hue": 0,
  "on": true,
  "reachable": true,
  "sat": 0,
  "xy": [
    0.5053,
    0.4153
  ]
}
$ ph put -v /lights/10/state '{"ct": 250}' 
{
  "ct": 250
}
$ ph get /lights/10/state
{
  "alert": "none",
  "bri": 1,

Hi @ebaauw I have just updated my deconz and conbee II firmware and Iam having the exact same problem with the Osram bulbs and led strings now (no problem with Philips bulbs):

Light 1 OSRAM   LIGHTIFY A19 RGBW
Light 2 LEDVANCE    A19 RGBW
Light 3 OSRAM   LIGHTIFY FLEX OUTDOOR RGBW

How can I create the same exception for these ? Thank you

I am also having the same issue. I lost the ability to change the color temperature of my Ledvance lights. I run circadian lighting and now my Ledvance fixtures won't stay in sync with the rest of the CT lights in my house. HELP!
