    Electronic module with LED components and an integrated circuit on a board marked XQ-17072. Close-up of an electronic module with visible components like an integrated circuit and quartz.

    Bought a cheap aliexpress tuya downlight and for my surprise it was a BLE only, im new to all of this, any help? I have esp32 s3's so being a Bluetooth is not that huge of issue, but i without knowing went for it.

    Which device model is that? What kind of information was on the packaging and seller's site?

    It looks like you either bought or was sent a BT-only version by accident.

    >>21316876 I dont know. Its a generic one from Aliexpress, in Tuya iot plataform it shown as: 8003 pwmRGBCW 5

    The DPs are:
    "code": "switch_led",
    "dp_id": 1,
    "type": "bool",
    "value": false

    "code": "work_mode",
    "dp_id": 2,
    "type": "enum",
    "value": "white"

    "code": "bright_value",
    "dp_id": 3,
    "type": "value",
    "value": 10

    "code": "temp_value",
    "dp_id": 4,
    "type": "value",
    "value": 0

    "code": "countdown",
    "dp_id": 7,
    "type": "value",
    "value": 0

    "code": "colour_data_raw",
    "dp_id": 11,
    "type": "raw"

    "code": "music_data_raw",
    "dp_id": 13,
    "type": "raw"

    "code": "do_not_disturb",
    "dp_id": 34,
    "type": "bool",
    "value": false

    "code": "strip_scene",
    "dp_id": 73,
    "type": "raw"

    "code": "strip_local_timer",
    "dp_id": 75,
    "type": "raw"

    They constantly shows as offline in iot plataform, i guess because i don't have a tuya gateway, but works fine paired to the smartphone.

    I tried to make it work with ha_tuya_ble repo and using my esp32 as a proxy but no luck.

    Product id is: "heflj0rj" category: "dj"

    Edit: found the maker and the model, website is: https://rgbcct.en.alibaba.com/?spm=a2700.shop_plser.88.12.4ae23b1bEypFuD the product is the TY-SL-15W

    Sent them a message asking info about the microcontroller, lets see.

    edit2: also found this https://fccid.io/2BDTU-TY- but the schematics are confidential.

    What now? I desolder it? I should create a topic? Any topic or section that i should read?
