    Hi,

    I want to share my knowledge about Hama 176581 E27 RGBCW Bulb. I have flashed the bulb via Tuya-Cloudcutter (via manufacturer and I have selected as Device the Hama E27 Bulb 176584). Inside the bulb is a BK7231T chip.
    I prefer using OpenBK, but I didn't found a config for the bulb. For that I have installed ESP-Kickstart. With ltchiptool I could extract the config:
    (PWM Bulb // key: keytg5kq8gvkv9dh)
    red // pin P26 // PWM // inverted false // Channel 0
    green // pin P6 // PWM // inverted false // Channel 1
    blue // pin P24 // PWM // inverted false // Channel 2
    cold // pin P8 // PWM // inverted false // Channel 3
    warm // pin P7 // PWM // inverted false // Channel 4

    I tested the config on 3 different bulbs and it was always working.
    I am new at this forum. Could someone upload this config, that it will be also available at OpenBKs-Web-Application?

    Can someone tell me how I can switch from ESP Kickstart to OpenBK via OTA Upload?

    I think you can easily extract config on any OBK device:

    I don't know much about kickstart because they have some kind of strange, non-standard OTA format, but this guy seemingly provides files for update:

    Then you can just manually update OBK to latest version:
