Fairy Lights with preset colors

[jaydensmith]

I have some Tuya fairy lights that I'm trying to set up. The lights have no brightness controls, and you can only choose from a preset list of colors (see screenshot).

I've been able to get them to power off/on with the following config.

host: 192.168.1.202
device_id: 82005237600194dd6fce
local_key: 095573c690e00b9e
friendly_name: Tuya Fairy 1
protocol_version: "3.3"
entities:
  - platform: light
    friendly_name: Fairy Lights 1
    id: 20
    # color: 101 # Optional, usually 5 (RGB_HSV) or 24 (HSV), default: "none"
    scene: 102 # Optional, usually 6 (RGB_HSV) or 25 (HSV), default: "none"

If I set the color parameter, the entities become unavailable, as the integration doesn't support color changing lights with no brightness.

The DPS response I get from the device is:

It seems that the 101 DPS is responsible for the color, and 102 for the scene.

The available list of colors responses are:

• Color (cycles through all the colors)
• R (red)
• RG (yellow)
• G (green)
• GB (light blue)
• B (blue)
• RB (purple)
• RGB (white)

The available list of scenes that I have working (the keys and values are the same):

SCENE_LIST_RGB_1000 = {
    "Bright": "Bright",
    "Gradually": "Gradually",
    "Star": "Star",
    "Flower": "Flower",
    "Marquee": "Marquee",
    "Fireworks": "Fireworks",
    "Meteor": "Meteor",
    "Stream": "Stream",
}

Ideally so the device can be color controlled by Google Home etc. I'd like to map segments of the color wheel to the preset colors. Do you think this is possible?

maybe you can add output of tinytuya in monitor mode (example script is provided)
Think, this makes it more easy to find a solution for the integration.

Maybe you also have a look at #659

Which I think is from my Genio LED strip.

8a1c6e0 seems kind of similar to this, just on a different attribute - but I'm seeing it on master.
