[BK7231T] Aoycocr GU10 RGBCCT 4.9w Q3SCWM Teardown + Settings

Hi there,

i found these on eBay for around 4,50€ a pop (26,99€ for 6). Manufacturer on the box and on the bulb seem to differ. On the box it is LVWIT and on the Bulb Aoycocr. The Bulbs themselves give a rather cold light even on the warmest setting. I would recommend them rather for a workplace environment:



Teardown is pretty simple:
- pry open the cover
- unscrew the two screws
- Everything slides out nicely


The board is surprisingly simple. Everything is right on the emitter plate. Some Pins are exposed on the PCB bit I didn't bother testing them since tuya-cloudcutter worked just fine with the main module being on version 2.9.6( 2.9.6 - BK7231T / oem_bk7231s_light_ty
) and 1.1.2 (1.1.2 - BK7231T / oem_bk7231s_light_ty).


BK7231Flasher yielded:


Config working for me is:

Thanks for the guide. You are lucky that those LEDs have wires long enough to take out the board without breaking the pins. I remember having some issues with reassembling GU10 pins some time ago, we've looked into it with @ferbulous and it turned out that some of GU10 LEDs are problematic in reassembly.

It is also interesting to see BK on the LEDs board itself, I am not sure if I have seen such a design already.

Yeah, I like the simple design. The antenna sits in the front, making it somewhat directional, but it's working really well for downlights. They are probably the IoT appliances with the best reception in my house.

I just got another box and the bulbs were completely different. So I guess it was just a mispackaged box the first time. New ones are already in the DB.

Aren't they still flashable?

Yes sure. New ones are actually labeled LVWIT and flashing worked following https://www.elektroda.com/rtvforum/topic3938630.html. Just thought I'd mention it so others might stumble over it.

That's great to hear, now you have a lot of cloud-free bulbs.

Remember to check out our devices groups support, which can be useful for controlling LED lighting:

Thanks for the heads up. I already configured it. Now looking into DDP integration with WLED and still fighting with OpenHab HSB Color model to RGB conversion. But that's on OpenHab's side until OpenBeken supports HSB model via MQTT. Looking into the source now.

Wait, isn't HSB support already in OBK? Via Tasmota command? HSBColor?

Haven't tried via Tasmota command yet. And MQTT get state reflects RGB. Maybe I can get it via State or Result.

Edit: Once I got it figured out, I will write up a tutorial for OpenHAB integration via MQTT.
