Device Name: Mirabella Genio Wi-Fi LED USB Desk Lamp With Wireless Charger - I003867
Device Type: Desk Lamp with Qi Charger
Device Chip: WB3S - BK7231T with TuyaMCU
Device Purchased Bunnings Warehouse - $29.95AUD - Appears they not stocking this anymore and selling last of stock

Flashing of Main Chip

CloudCutter Profile - Profile.json

I created a CloudCutter profile using LightLeak.

WB3S Module Datasheet

Configuration of Module

I still haven't worked this out yet. I have nothing configured and the device works if you press the buttons on the physical device. As far as I can tell this is using a TuyaMCU to change the light settings.

After looking at the profile.json I think these are the dpID values and what they do

dpID 1 - enum - Light Mode - cool, white, warm.
As per json it states 4 settings. Breathe, nature, read, night but when pressing the physical button it only cycles 3 settings

dpID 2 - value - Dimmer - Query dim light down to min of 25

dpID 3 - value - Dimmer - Query brighten light up to 255

dpID 4 - bool - Light ON/OFF

Setup with this code but nothing works

startDriver TuyaMCU
setChannelType 1 Toggle
setChannelType 2 LowMidHigh
setChannelType 3 Dimmer
setChannelType 4 Dimmer
tuyaMcu_setDimmerRange 0 1000
linkTuyaMCUOutputToChannel 4 bool 1
linkTuyaMCUOutputToChannel 1 enum 2
linkTuyaMCUOutputToChannel 2 val 3
linkTuyaMCUOutputToChannel 3 val 4

However, looking at the OBK logs it's a different story

Pressing - Light ON/OFF

Pressing the Dimmer button - holding down the power button makes the light dim and holding it down again will brighten the light.

I get this while holding the power button

There is a timer button that when held down sets the light to turn off in 40 minutes. This doesn't log anything

So after looking at all this. I think these are the dpID values and what they do

dpID 1 - bool - Light ON/OFF

dpID 2 - No idea

dpID 3 - value - Light Mode - cool, white, warm. ? also does dimming

dpID 4 - value - Light Mode - cool, white, warm. ? also does dimming

I think the dimming/brightening might have something to do with the int: command maybe? It's the one that changes

Setup with this code - it kinda works

startDriver TuyaMCU
setChannelType 1 Toggle
setChannelType 3 Dimmer
setChannelType 4 Dimmer
tuyaMcu_setDimmerRange 0 1000
linkTuyaMCUOutputToChannel 1 bool 1
linkTuyaMCUOutputToChannel 3 val 3
linkTuyaMCUOutputToChannel 4 val 4

dpID 1 - Turns light ON if off but will not turn light OFF if on

dpID 2 - Nothing

dpID 3 - Query brightness level - The slider does change light but the slider defaults back to 0. Brightness does stay changed

dpID 4 might be the mode change as when moving the slider the temperature of light changes depending on where you move the slider but it doesn't work correctly and the slider defaults back to 0. Light does stay changed temperature. Light also does not change to all temperature levels

I've tried changing the channel type to see if there is something that might work better than sliders and toggles but still can't get anything to work.

Will keep trying to work this out and will post here if I get it sorted. I've not worked with TuyaMCU before so I'm sure it's something I'm doing.

Cool? Ranking DIY

Some TuyaMCU devices needs to be "paired" first before using. Can you try forcing the 0x04 WiFi state (paired) and retry?
Add the following line to autoexec.bat script after TuyaMCU init:
Code: text Expand Select all Copy to clipboard
tuyaMcu_defWiFiState 4

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

I added the code to the autoexec.bat but still nothing.

I'm sure I don't have the dpID's set up right. I just have to work out what is going on.

I did try to dump some data using the TuyaMCU Analyzer but it returns nothing. I don't have the stock firmware so I can't reflash the device and see if that produces anything.

Might just have to keep playing around with things. The physical buttons work fine, I just can't get anything to work with the webGUI.

Added after 2 [hours] 40 [minutes]:

So I ran my OBK log through TuyaMCU analyzer and it spits out this

I tried this

Code: text Expand Select all Copy to clipboard
startDriver TuyaMCU tuyaMcu_defWiFiState 4 setChannelType 1 Toggle setChannelType 3 Dimmer setChannelType 4 Dimmer tuyaMcu_setDimmerRange 0 255 linkTuyaMCUOutputToChannel 1 1 1 linkTuyaMCUOutputToChannel 3 2 3 linkTuyaMCUOutputToChannel 4 2 4

Still had issues with power, brightness and temperature mode so I turned on Flag 8 and this fixed the problem.

It appears this device is now working. Every now and then it is a bit slow to update. Would be nice to see the webGUI have a temperature slider and brightness slider like you get with the RGB lights but as I don't really use the webGUI it's not a huge issue.
