  • Here is short "teardown" of Energy+ (Home Connect) Smart LED CCT GU10 5W. 400 lm, 3000-6500K.
    This brand is exclusively in the Finnish market, so you probably won't ever find it abroad.
    It had V2.9.16 Tuya firmware inside, so you can flash OpenBKT with tuya cloudcutter.

View of a white LED bulb lying on a gray surface with a teardown tool. Box of Energy+ Smart LED GU10 bulb. Back of Energy+ Smart LED CCT GU10 bulb packaging with barcode and CE markings.

    Device configuration, as extracted from Tuya:
    - LED Cool (Channel 4) on P26
    - LED Warm (Channel 5) on P24
    Device seems to be using WBLC5 module, which is using BK7231T.
    And the Tuya section starts, as usual, at 2023424

    Help is needed also. I can't turn bulb on or off with toggle button on index page.

    OpenBKT user interface with smart bulb information.

    I can only toggle it on or off with status page buttons.
    User interface showing device status with PWM channels for an LED bulb.

    Any ideas what im missing right now ?

    That's strange.... let's investigate this problem. How do those sliders in the Web App work for you? The ones in the Web App?
    Is one linked to warm white brightness, and second to cool white brightness?
    Or is one responsible for color temperature adjustments, and second for brightness?

    Also, are sliders on native HTML panel not working? What do you mean by saying that toggle is not working? Is bulb always on? Always off?
    Helpful post? Buy me a coffee.

    Thanks for the fast reply @P.Kaczmarek2.
    In Web App "status page", one is for cold white (4:0 role PWM) and second one (5:0 role PWM) is for warm white. I can turn them on/off and adjust them in Web App status page. So this page works as it should

    This page doesn't do anything:

    Bulb is always off when trying to control it from the native html panel.

    hmm what is the device template in the web app?

    Can you try... changing channel 4 to 0 and channel 5 to 1 in the pins settings?

    There might be a small logical error somewhere that I need to fix

    Thanks, changing channels was the key, now it's working like a charm :)
    EDIT:
    Channel 4 to 1 and Channel 5 to 0 was right one.

    Still, it's a bug. Let me look into it. It should be fixed by evening.

    @Nimierkki I have submitted a fix for your issue, with future updates, it should always work, even with channels 4 and 5. Thank you for pointing out that issue to me!
