    Hi, could this be any chance using ewelink app since it's BL602 chip?

    I do not know about ewelink, default application - Magic Home.

    As far as I know Magic Home devices does not work with eWeLink App. They have totally different SDK used, they are not even Tuya...

    I will look into supporting this new chip, wait. The device reminds me of ws2812 LEDs. Here is english datasheet:

    I started looking for an alternative firmware to the device because the integration "Magic Home" in the Home Assistant only allows to turn the lamp on and off.

    Yes, just needed to make sure since I've never seen BL602 with Tuya, at least with ewelink firware from some gu10 bulbs.
    I did purchase Magic Home LED bulb, but that one's using a chip i've never seen before (CC8000)

    CC8000, I have one piece of this chip.
    I have one because I bought that item: HLK-B30-V1.0

    Low consumption BLE4.2+WiFi 2.4G wireless module BK7231U
    with 256KB ram and 2M flash
    HLK-B30 is a low-cost embedded UART-WiFi (serial-wireless network) module launched by Hi-Link Electronics.
    This product is based on an embedded module that complies with the network standard through a serial interface and has a built-in TCP / IP protocol stack.
    With the HLK-B30 module, traditional serial devices can transmit their own data over the Internet without changing any configuration, providing a complete and fast solution for users' serial devices to transmit data over the network.
    Notes:
    To ensure that all configuration procedures are correct, first reset the module to factory settings. Modules that are already in factory mode can skip this step.

    Press and hold the ES0 key on the baseboard for 6 seconds to restore the factory settings.

    This product is just the WiFi&Bluetooth module HLK-B30, if you need the test board, please contact me for details.

    It was supposed to use BK7231U, but look what they sent me - CC8000:

    Help me, please
    I flashed 1.14.133, installed UCS1912_DIN on GPIO12.
    Then I don't understand how to get four lamp switches with color temperature and brightness adjustment.

    Please wait, @Sergio127 . It is not functional yet. I only started working on it and added a driver as a stub. I am working with a scope to check the waveforms. Hopefully I will get this running in the following week. When a basic version is ready, I will need you to run some test commands in console and tell me if anything lights up.

    ok, I'm waiting.
    P.S. I found a marking on the tube with LEDs, maybe it will be useful

    The LED strip has 3 contacts: 1 positive common (red), 2 - negative red LEDs (black), 3 - negative blue LEDs (white). No data pin.
    If you give a 12 volts to the common contact and negative both, then the lamp shines at full power.
    UCS1912 is a simple 12-channel dimmer. 0 - off, 255 - maximum brightness on each channel.

    The firmware version number never changes.
