I created a CloudCutter profile using LightLeak.
I attempted to flash several times but was unsuccessful. It would get to loading the new firmware but appeared to have trouble uploading it. It could have been an error on my end or an issue with the LightLeak profile I created. After many fail attempts I ended up manually flashing the chip with BK7231 GUI Flash Tool. It worked first try.
Light working as expected. If RGB colours are wrong use SM2135_Map
You can enter this command on the Logs tab in the "Command" box. Hit submit and it should update the colour map. I understand that the config with stay with any updates going forward. Will update this post if that is not the case.
My light colours before setting the SM2135_Map was
Red = Blue
Blue = Green
Green = Red
Warm White = Cool White
Cool White = Warm White
enter - SM2135_Map 0 1 2 4 3 - This should fix the issue.
Setting Flag 18 also helps with smoother transitions.
I believe there is a Music/Disco mode that works on the Mirabella Genio app. I haven't bothered to work this one out as it's not a function I'd ever use. Feel free to give it a go if that is what you need.

I uploaded a picture of the U1. It's a SM2135EH - BGBISYAA05. Also looking at the LED's they appear to be SM2835's. Not sure if that makes any difference. I have tried setting the SM2135DAT and CLK to... [Read more]

Please do not try at random. When you look at this photo:

Not really trying at random. Been sticking with these pins below as they are the only ones that I can see would be correct.

Very good job on figuring that out. It will be useful for our templates list.
Now, do you know how to change the colour order?
Look up SM2135_Map function.

Took some stuffing about but finally got there.
Been messing with the SM2135_Map config. After much messing about with values it ends up it was just the default 0 1 2 3 4 setting.

How do I flash custom firmware when CloudCutter fails?
Use the BK7231 GUI Flash Tool over UART. In the thread, nine CloudCutter attempts failed, but the GUI tool succeeded on the first try.[Elektroda, wolfieeewolf, post #20462594]
A basic multimeter in continuity mode lets you map CLK and DAT in minutes; price starts around US $10.[Fluke Basics] "Stop random trials and probe first."[Elektroda, p.kaczmarek2, post #20463838]
What can go wrong during flashing?
Repeated OTA attempts can brick the bulb if power drops. CloudCutter stalled during firmware upload nine times in the thread—an edge case linked to the LightLeak profile.[Elektroda, wolfieeewolf, post #20462594]
How do I flash with BK7231 GUI Flash Tool (3-step)?
Solder RX, TX, 3V3, and GND to the CBU pads.
Hold CSN low, power the bulb, then click “Flash” in BK7231 GUI.
After success, reboot and configure pins in OpenBK.
What are the power and brightness specs?
The globe draws 15 W and produces 1,400 lumens, yielding approx. 93 lm/W efficiency.[Bunnings Product Page]
Will future firmware updates erase my colour mapping?
Do I need safety precautions when opening the bulb?
Yes. Disconnect mains, wait 30 seconds for capacitors to discharge, and use insulated tools. LED driver capacitors can hold 325 V DC even after power-off.[IEC 60598 Safety Guide]
