1. Which Wi-Fi chip does the COLOROCK Mini Relay use?
It ships with a Tuya CB2S module containing the BK7231N Wi-Fi SoC [Elektroda, mattj, post #20471342]
[BK7231N] COLOROCK Mini Smart Relay WiFi Switch 16A
TL;DR
- COLOROCK Mini Smart Relay WiFi Switch 16A is a small in-wall relay that looks like the Aubess model but appears to use a different board.
- It uses a CB2S module with a BK7231N chip, and flashing works by soldering directly to the Tuya chip without disconnecting it.
- BK7231Flasher runs at 115200 baud, and the OpenBeken pin map assigns pin 8 to LED and pin 24 to Relay.
- An original firmware backup was saved, but its usefulness and upload location are still unresolved.

Hey all -
Yet another small in-wall relay. Looks very similar on the outside to the Aubess model, but it seems with a different board (so I figured it was worth it's own thread.)

Chip: CB2S (BK7231N) https://developer.tuya.com/en/docs/iot/cb2s-module-datasheet?id=Kafgfsa2aaypq
Flashing:
Simple enough to flash, solder directly to the Tuya chip (no need to disconnect). Use BK7231Flasher at a 115200 Baud Rate.
I have a copy of the original firmware backup, not sure if that would be helpful / where to upload.
OpenBeken Config:

Thanks, it seems like a very simple device, but I think you are still missing at least one IO role. The button on the case is separate from the switch, I think. Btw, you can upload the binary 2MB here,... [Read more]
Yes, you are correct about the button. I never bothered to test it (don't feel comfortable touching on the device while it's connected to the mains voltage), since I don't intend on using it. I've... [Read more]
I think that I could also extract pin mapping from 2MB firmware backup. [Read more]
Original FW attached. I will also try to submit to the Tuya CloudCutter team. [Read more]
Okay, so we know where is the button, then which pin is used for the switch? For the toggleChannelOnToggle role? [Read more]
Sorry not sure I follow the question? The config I found that works is to set P24 as a Relay. [Read more]
How is the power supply of this module? What system is responsible for the 230V / 5V converters? [Read more]
