Is CCT mode available through the Tuya integration? I cannot get it to work.

Is CCT mode available through the Tuya integration? I cannot get it to work.

Not yet. That is what this issue is about.

[jbusuttil83]

@N3m3515 there is this PR open about it.

[N3m3515]

@N3m3515 there is this PR open about it.

But the PR is not for this specific Light?

[wedsa5]

Tuya should already support CCT afaik. The issue mentioned (and PR I opened) won't necessarily fix your problem. You should try testing it out with the provided code fix (in the PR) and your specific bulbs. The issue is about bulbs that don't support color temperature, but just a white mode.

Your bulb is likely not supported because the field "category" with value "tyd" is not in the list of available lights.

If you check light.py in the tuya component, you will see a pre-defined constant called LIGHTS which defines all the light categories and their TuyaLightEntityDescription. tyd is not in the list and needs to be added. Normal lights, like the one in the mentioned issue, are category dj.
