OSRAM Lightify A19 Tunable white bulb shows RGB controls

Configuration Zigbee

As the title states, here is what I see:

OSRAM Lightify A19 tunable white settings
OSRAM Lightify A19 tunable white settings394×743 43.5 KB

How do I remove the RGB controls?

Also, The tunable white range is wrong. The “max” mireds setting (lower Kelvin temp) is not available. Its range is 6500K - 2700K (154-370 mireds). The slider position above is the max mireds the bulb will accept.

I opened a issue for this a while back: https://github.com/zigpy/zha-device-handlers/issues/135

I looked into it some with one of the zha devs, and it was not a trivial fix and these bulbs were so unreliable for me I got rid of them all so lost interest.

Oh my, that was over a year ago!
I got a little bit further than you did with my issue posted here: https://github.com/home-assistant/core/issues/39857#issuecomment-689719990

With assistance from Alexei Chetroi (@Adminiuga) at https://github.com/home-assistant/core/issues/39857 this is now fixed!

docker stop homeassistant
find /var/lib/docker -name a19twhite.py

and edit the file so it looks like the following:

    }

Changes:

from zigpy.quirks import CustomDevice

to

from zigpy.quirks import CustomDevice, CustomCluster

Add:

class OsramColorCluster(CustomCluster, Color):
    _CONSTANT_ATTRIBUTES = {
         0x400a: 16,
         0x400C: 370,
    }

In Replacement section,
change:

Color.cluster_id,

to:

OsramColorCluster,

And then docker start homeassistant.
