    I've successfully flashed my "LSC RGB Ceiling Lamp" using Tuya Cloudcutter and connected it to Home Assistant. This ceiling lamp looks quite similar to another device I did a teardown for: LSC Smart Ceiling Light. It is using the same LED PCB, it uses the same module, but internally is using another MCU module.

    I bought this ceiling light a few years ago in the Netherlands at the shop "Action".

    Tuya app given info
    Product name in Tuya app: "LSC RGB Ceiling Lamp"
    The module version in Tuya app: "v1.1.6"

    Additional info
    Mac-address lookup result: "Tuya Smart Inc."
    Product marking LED driver: "LED Driver, CL20W WiFi-RGB"

    "Selected Profile: oem-bk7231s-light-ty-1.1.6-sdk-2.0.0-30.06"

    Led driver
    The lamp uses a "sm2125" led-driver with data-pin=P24 and clock-pin=P26. I'm unable to read the small print, but this is the only i2c driver which I found to be working.

    Thanks! I am adding this device to our list now, and I have one question, do you know the Action store product model for that lamp?
    I am asking because:

    "Selected Profile: oem-bk7231s-light-ty-1.1.6-sdk-2.0.0-30.06"[/url]

    There is indeed a model number like 970706 , but 970706 is a GU10 bulb which was used for Tuya-cloudcutter profile. Are you able to tell the Action store model for that particular lamp you've shown?
