CLOUDY BAY 6inch Smart Wifi LED Recessed Lights, RGBCW

justinhunt1223 

I purchased these lights on Amazon. Teardown is simple, remove the 6 screws on the back of the downlight. The board is inside a white heat shrink. Cut along the edge with a razor so that you can simple slide the heat shrink back over the board after you're done.




I removed the WB3S module with a heat gun and stuck it in a DORHEA ESP8266 Code Burner to flash it. You may try flashing it while its installed but it wouldn't work for me with. Flashing while installed does work. My old serial programmer was malfunctioning. I successfully read and flashed it while installed using the DORHEA ESP8266 Code Burner.

Pin configuration:

P6: PWM/5
P8: PWM/4
P9: PWM/1
P24: PWM/2
P26: PWM/3

After configuring the device and prompting the home assistant discovery, home assistant picked up the device and allowed me to control everything without any further configuration.

The pictures here are of a light that had a catastrophic failure (I quickly assembled it for pictures here). I accidently shorted out a handful of pins on the back on a piece of metal, whoops.

Edit: attached stock firmware.

Hello, would you be able to provide some more pictures of your device, how it looks like from outside and maybe inside, and if not, maybe some screenshots from the shop offer where it was bought? [Read more]

No problem. I see you did well with the heatgun, although I think it would be also possible to flash it in place, you just need a reliable 3.3V power supply (not the cheapest one that is on the board of... [Read more]

I have a handful more of these lights to flash and would love to not have to remove these to do it. I will attempt them in the next week and report back. I think my new USB -> serial on the way might ... [Read more]

Hi my friend, maybe oyu can provide a stock firmware dump from these device. And then could cloudcutter work on it. [Read more]

Indeed, a factory flash backup can always be useful. That's why our new flash tool (still in Alpha stage) suggests to do automatic backup and then flash: https://github.com/openshwprojects/BK7231GUIFlashTool ... [Read more]

I don't mean the dump. I mean he should check the GitHub of Cloudcutter to flash it OTA and not to desolder all the spots. But the dump is necessary for the flash, when this firmware wasn't added by n... [Read more]

It is very hard to determine what is going on with your lights. If you are experiencing issue related to the range of the WiFI, then I am not sure if we can help much, because we just replace the firmware... [Read more]

specialdude 04 Dec 2023 15:45
