What is it

This a third-party home assistant custom components works for Cozylife Lights based on the official repository. The official repo is buggy in too many ways. This one heavily modified.

It is a pure local version and does not use UDP discovery.
The color temperature is fixed.

features

heartbeat to each bulb in a fix time interval to test the availability. Even if the bulb is not available during the time of setup or later, it can pick it up if the bulb goes online again.

fixed the color temperature

Tested Product

Tested it on color bulbs (no homekit). It can be initialized though bluetooth.

It has also been tested on color bulbs (with homekit). It can run both Apple homekit and Home Assistant simultaneously.

Switch and CW lights are not tested yet. CW lights should work.

How I Setup the bulb

The bulb will phone home to dohome.doiting.com. I blocked the dns request (you might also be able to block the internet access entirely, have not tested). This makes the registration process half complete. But the app could transmit the wifi name and password to the bulb. In principle, if you complete the full registration with the cloud, the bulb will respond to UDP discovery. However, my bulbs does not respond to UDP discovery, not sure if is because the code I used was buggy.

Instead, we run a TCP scan on the operating port 5555 through a specific ip range.

Note that for we must have persistent IP address otherwise the config will change. Thus can be done on most routers.

Sample config

Run the following getconfig.py with two parameters ip start and ip end.

python3 getconfig.py 192.168.1.193 192.168.1.194

to obtain something like

light:
- platform: cozylife
  lights:
  - ip: 192.168.1.193
    did: 637929887cb94c4cffff
    pid: p93sfg
    dmn: Smart Bulb Light
    dpid: [1, 2, 3, 4, 5, 7, 8, 9, 13, 14]
  - ip: 192.168.1.194
    did: 637929887cb94c4ceeee
    pid: p93sfg
    dmn: Smart Bulb Light
    dpid: [1, 2, 3, 4, 5, 7, 8, 9, 13, 14]

Copy it to the relevant configuration file (yaml). Here the did is the same as of the official app (unique id). pid, dmn, dpid are also the same as the official app.

Optional requirements

Circadian Lighting

I used a modified v1 version (with Astral v2 dependance). v2 is not tested.

Notes and todo

Nothing is encrypted. If it talks to the cloud, I guess it also talks to the cloud unencrypted. In the file model.json, even the ota update file is not encrypted. If someone could crack it. One might be able to flash custom firmware via OTA.
Implement effects, the formats are listed below
The color is not accurate at all (to be fixed? I am not sensitive to colors).

summary for control parameters:

'1': on off switch
'2': 0 normal change to color / color temperature with a transition period
'2': 1 with special effects
'4': brightness
'5': hue
'6': saturation
'8': speed of change
'7': consists of two bits of operator and 7 colors
colors are in the format of HHHH SSSS TTTT where HHHH SSSS are hue and saturation. TTTT is color temperature.
In color mode, TTTT=FFFF.
In white mode, HHHH SSSS =FFFF FFFF.

operator code for effects:

List (applicable to color or color temperature, or a mix of the two)

04: 1 on off rotation 05: 2 on off rotation 06: 3 on off rotation 07: 7 on off rotation

08: 1 slowly diming 09: 2 slowly diming 0a: 3 slowly diming 0b: 7 slowly diming

0c: 1 fast flash 0d: 2 fast flash 0e: 3 fast flash 0f: 7 fast flash

Only for color

00: 1 smooth change color rotation 01: 2 smooth change color rotation 02: 3 smooth change color rotation 03: 7 smooth change color rotation (rainbow effects)

Note for color temperature

00: brief dim and increase back up '8' does not matter, 01 FFFF FFFF TTTT. 01: identical to mode '2':0, but it is a sudden change instead of a smooth transition.
