What radio module and MCU does the Energy+ GU10 use?
It carries a WBLC5 Wi-Fi module built around the BK7231T microcontroller [Elektroda, Nimierkki, post #20853137]
Exploring the Energy+ Smart LED CCT GU10 5W with BK7231T and WBLC5 - A Teardown
TL;DR
- A teardown covers the Energy+ (Home Connect) Smart LED CCT GU10 5W, a Finnish-market smart bulb rated 400 lm and 3000-6500K.
- Inside, it uses a WBLC5 module with BK7231T, and Tuya extraction mapped LED Cool to P26 and LED Warm to P24.
- The bulb shipped with Tuya firmware V2.9.16, and the Tuya section starts at 2023424, so OpenBKT flashing via tuya cloudcutter is possible.
- A generated script clears GPIOs and LFS, then assigns pin 26 to PWM channel 4 and pin 24 to PWM channel 5.
- The main problem is control: the index-page toggle button does not switch the bulb on or off, while the status-page buttons do.

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.
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.
I can only toggle it on or off with status page buttons.
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... [Read more]
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... [Read more]
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 [Read more]
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. [Read more]
Still, it's a bug. Let me look into it. It should be fixed by evening. [Read more]
@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! [Read more]
