Hi,

I have a garage batten Led light:

I have successfully flashed with BK7231N - 1.17.157
It is on the Wwifi and I can connect to the interface.

looking at the Tuya GPIO file with bk7321flasher I get the below:


{
	"rstnum":"3",
	"rstcor":"c",
	"Jsonver":"1.0.1",
	"brightmin":"15",

	"mst_tp_2":"0",
	"mst_ver_2":"null",
	"mst_tp_3":"0",
	"mst_ver_3":"null "
}


Device configuration, as extracted from Tuya: 
- LED Cool (Channel 4) on P7
- LED Warm (Channel 5) on P6
Device seems to be using CB3L module, which is using BK7231N.
And the Tuya section starts at UNCOMMON POSITION 0

I have configured it accordingly however I cannot turn it on or off as there are things missing I think.

Can anyone help with the Turn Off/Turn On part of the configuration?

Thanks

Hello, what do you mean by "turn on and off", how your current OBK main page looks like? Do you have a temperature slider? Is the "On"/"Off" button showing up there? Is it working?

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:

Yes, all is there on the main page. Nothing is missing.

But with the current GPIO configuration, the light doesn't turn off or on when I press the button on the web page.

So what do the sliders do? Do they work correctly?

Or do you observe something like, I don't know, temperature slider is changing brightness, etc?

Maybe you need the "alternate CW mode" flag?

That is what I am saying - nothing happens. I press the ON button on the main page - The lights do not come on.
Since lights are not on when I press the OFF button nothing happens.

As the lights are not ON then the sliders will not work either.

So in summary - can not turn ON the lights.

Ok, so, maybe, let's try with basics. Use GPIODoctor to test each pin in relay mode (on and off), try to set all pins to state 1 (ON, aka high) and tell me, does anything light up?

Ok only PIN 6 and PIN 7 turned ON the light.
PIN 6 - Warm White
PIN 7 - Cool White

The rest of the PINS did nothing

Added after 7 [minutes]:

But now the front page looks like this

Ok, now change the roles of P6 and P7 to PWM, does the light work now?

If not, go to flags, enable "show raw PWM controllers" to show raw sliders for each PWM. Change those sliders on main page. Do they adjust the light colors, one for cool, second warm?

Changed them:

Enabled the raw option but there is no button for ON or OFF on the main page now:

Sliders do work and light dims or increases if I use them.

And now, if you disable "show raw PWM controllers", does the main page work?

If not, try setting cool channel to 0 and warm to 1...

Setting the PWM 6 to 1 and PWM 7 to 0 seems to have worked.

However, there is one issue - the light is not as bright as it was when it was running the Tuya firmware. It is much dimmer now.
I find that when I go to GPIO Doctor on HIGH, the light is much brighter too.

Any ideas?

What do you have on the main page now, what are the channel values at full brightness?

Maybe you need to enable alternate PWM frequency in flags.

This is the main page now, with light working:

I will try your suggestion and see.

I also have this same exact brightness issue with another vendor's device, what I flashed with Openbeken. Did you find any solution?

@Nimierkki Keep in mind that for "I2C" LED drivers like SM2135 or BP5758, you can set the current via console command. Or is your device using PWMs without any custom controllers?

Lights installed.
They seem very bright in the garage - the issue where they seemed not that bright might had been a perception error.

Topic summary

The discussion revolves around configuring GPIO for a garage batten LED light after flashing it with BK7231N firmware version 1.17.157. The user successfully connected the device to Wi-Fi but faced issues with the light not turning on or off via the web interface. After troubleshooting, it was determined that only specific GPIO pins (PIN 6 for Warm White and PIN 7 for Cool White) activated the light. Adjustments were made to the GPIO settings, including changing pin roles to PWM and enabling raw PWM controllers, which allowed the sliders to control brightness. However, the user noted that the brightness was lower compared to the original Tuya firmware. Suggestions included checking channel values and enabling alternate PWM frequency. Ultimately, the user reported that the lights appeared bright in the garage, indicating a possible perception error regarding brightness.
