Flashing Tuya WT5 dimmer with openbeken
Here is a flashing adventure for WT5 dimmers with opensource OpenBeken firmware.
preparation
Will flash openbeken firmware which is similar to Tasmota, but for chips used in Tuya devices. Got OpenBK7231N_QIO_1.17.451.bin.
I’ve found two flashers:
- python script https://github.com/OpenBekenIOT/hid_download_py
- gui app https://github.com/openshwprojects/BK7231GUIFlashTool
Here I would use python script, but I have also built a GUI.
Preparing tools.
console flasher
Initialize virtualenv for python flasher and install it.

gui flasher
This flasher written in C# and could be built with Mono under Linux.

flashing chip
here is pinout from https://developer.tuya.com/en/docs/iot/cb3s?id=Kai94mec0s076
Pins we would connect UART to:
VCC8GND9RXD115TXD116
I have soldered thin copper wires to this pins & connected my USB UART.
Somebody from community got a nice video which shows what to do https://www.youtube.com/watch?v=F1hV6AIMZXU
In my case flashing went smoothly, I’ve need to reboot device for a few times rerunning uartprogram.
(.venv) ~/projects/src/github.com/OpenBekenIOT/hid_download_py λ uartprogram OpenBK7231N_QIO_1.17.451.bin -d /dev/ttyUSB0 -w -u -s 0x0 UartDownloader.... programm.... Write Successful: |##################################################|[ 15.3k/s]
After that OpenBK7231N_REDACTED open network appeared. Device web interface is at http://192.168.4.1
secure way to configure wifi network
I have discovered serial command interface is not working. I don’t like the idea of filling in wifi network password using unprotected network (this is horrible idea).
More information
Startup script was:
startDriver TuyaMCU tuyaMcu_setBaudRate 115200 SetFlag 31 1 logPort 1
Connected to UART using:
picocom /dev/ttyUSB0 --baud 115200 --parity n --databits 8 --stopbits 1 --omap crcrlf
- input was echoed to me (which is expected)
- all commands ignored
- have tried different
omap’s without success
So, we will try to build firmware with hardcoded ssid & password.
TL;DR modified default configuration, but haven’t found any way to reset previously saved configuration on device, so flashed firmware which enforced default configuration then reflashed original firmware.

Device preserves configuration after flashing, which is good, but… there is no obvious way to reset this configuration (why in the world have you not implemented such an obvious thing?)
Let’s try reverting to GUI flasher, because it could somehow set this settings.
This doesn’t help. Such a horrible UX.
Ok, force default config:
diff --git src/new_cfg.c src/new_cfg.c index d89bb19d..6e61d2c5 100644 --- src/new_cfg.c +++ src/new_cfg.c @@ -726,6 +727,10 @@ void CFG_InitAndLoad() { addLogAdv(LOG_WARN, LOG_FEATURE_CFG, "CFG_InitAndLoad: Correct config has been loaded with %i changes count.",g_cfg.changeCounter); } + CFG_SetDefaultConfig(); + // mark as changed + g_cfg_pendingChanges ++; + // copy shortDeviceName to MQTT Client ID, set version=3 if (g_cfg.version<3) { addLogAdv(LOG_WARN, LOG_FEATURE_CFG, "CFG_InitAndLoad: Old config version found, updating to v3.");
And after this change I finally see device connected to my private network! (don’t forget to revert last change and flash original firmware)
God damn it, openbeken, why you can’t just be like Tasmota?! Wasted horrible amount of time solving such a usual thing.
configuration & MQTT
Here is minimal configuration which will setup this device as dimmer:
startDriver TuyaMCU tuyaMcu_setBaudRate 115200 SetFlag 31 1 logPort 1 loglevel 3 startDriver SSDP PowerSave 1 tuyaMcu_setDimmerRange 0 1000 setChannelType 20 toggle setChannelType 21 toggle setChannelType 22 dimmer setChannelType 23 dimmer linkTuyaMCUOutputToChannel 20 1 20 linkTuyaMCUOutputToChannel 21 1 21 linkTuyaMCUOutputToChannel 22 2 22 linkTuyaMCUOutputToChannel 23 2 23
MQTT support is available (see Mqtt* here).
