    Well, in worst case, you can just send me this module (instead of throwing it to e-waste) and I can make some kind of tutorial guide showing how to fix that kind of issue, but it's up to you.
    Helpful post? Buy me a coffee.

    Hi.
    I know my question probably has been answered, but I can't search here in 17 pages.
    Does the integration to HA needs to be via MQTT ? I don't use it neither I want to use. Is it possible to control directly ?
    My HA setup uses adaptative light integration for these leds.
    Thanks

    So it looks like I have the same bulb as https://www.elektroda.com/rtvforum/topic3889041-120.html#20151469, and the same issues as https://www.elektroda.com/rtvforum/topic3889041-450.html#21286241 with WPA2+WPA3 not working, only pure WPA2 on the CozyLife FW.

    Is this still going to be broken on OpenBeken FW even if I manage to flash this, which the previous person did not seemingly manage, or has this been fixed in OBK since?

    EDIT: Yes, it is the same, I have broken off an entire row of pads and one pad on the side.

    I should have desoldered the large capacitors first and hot air'd it properly - I already had components fly off so I didn't care much - new to using a hot air station. Oh well.

    WPA3 is supported in the SDK update from v1.18.95

Topic summary

The discussion centers on a custom Tasmota-like firmware replacement for the BL602 platform by Bouffalo Lab, enabling integration with Home Assistant via MQTT. Key topics include flashing the firmware using USB to UART converters, SDK compilation, and device pairing. Users report successful flashing on MagicHome LED controllers (RGB, RGBW, single color) and Sonoff devices, with detailed guidance on GPIO pin identification and configuration for PWM and relay functions. MQTT integration supports commands for color, dimmer, hue, saturation, and device control, with ongoing improvements to MQTT topic naming, discovery, and feedback reporting. Challenges addressed include MQTT buffer limitations causing device instability, startup behavior with LED blinking, and the absence of OTA updates for BL602 (unlike Beken platforms). The firmware supports saving and restoring channel states, configurable MQTT reporting flags, and plans for Alexa Hue emulation. Users share troubleshooting steps for flashing errors, network connectivity, and device crashes, with developer responses including bug fixes, feature additions, and testing requests. The project emphasizes open-source collaboration, aiming to free IoT devices from manufacturer servers, enhance privacy, and unify multi-vendor ecosystems under a single firmware solution.
