local handling for Tuya RGB tunable white light bulbs via home assistant

What is it for

Custome component of home assistant to locally control Color RGB light using Tuya firmware v3.3. Tuya firmware less than v3.3 are recommended to flash using tuyaconvert

Tested devices

• Feit color bulbs from Costco for 5$ each

Steps

• follow tuyapi to obtain local_key and device_id.
• example configuration.yaml

light:
  - platform: mytuya
    host: 192.168.1.88
    local_key: 010a4054efd304343
    device_id: fcefa33211c89a54c8dbil
    name: ceiling
    protocol_version: 3.3

Note

The following parameters might vary depending on your brand.

    DPS_INDEX_ON         = '1'
    DPS_INDEX_MODE       = '2'
    DPS_INDEX_BRIGHTNESS = '3'
    DPS_INDEX_COLOURTEMP = '4'
    DPS_INDEX_COLOUR     = '5'

Todo

• Implement async. The device responds to each command instantly, you cannot place the next command until half a second later.
• Implement custom scene. There are four different scenes. E.g., one corresponds to looping between up to about 6 colors. This could be mapped to a feature in home assistant.
• Implement a service that sends a command to the bulb for easier debug.
• Add Circadian support. Please see github for my current code.
