PR for template add are you sure PWM;0 though? I thought R=1, G=2, B=3, CW=4, 5=WW It's just on Beken only 6 pins can be used for PWM and they're referred to as PWM0-5 by Beken. But for OBK channel assignment it's 1-5

well, I never knew that! fair enough. You'd have complained about the colours being wrong or not working anyway, so seems obvious now.

>>21234797 All good, was a good exercise in understanding PWM some more with OBK, so I appreciate you pointing it out. Thanks for doing a pull for the config as well

Thank you, merged. Device should be soon live at: Channel indexes can start with 0. You could get more functionality of this device by using Btn_SmartLED, altough this button code itself could use more tuning. This LED controller can be also repurposed to 3x white strip independent control with PwmToggler. Added after 47 :EDIT: I can also see it has 5 transistors? So you can easily use it as RGBCW.

Thanks will check this out, was initially replicating tuya stock functionality so will likely do more. I also note the IR pads on the underside of the PCB and dumped tuya config seems to indicate P14 for their use, I imagine adding an IR diode would be relatively easy.

Kia ora divadiow,

If its best practice, I'm happy to change the channels.

Quote:
Red is 1, Green is 2, Blue is 3 (altough firmware will also support indexing started from 0)

Thank you, merged. Device should be soon live at:
https://openbekeniot.github.io/webapp/devicesList.html

Channel indexes can start with 0.

You could get more functionality of this device by using Btn_SmartLED, altough this button code itself could use more tuning.

This LED controller can be also repurposed to 3x white strip independent control with PwmToggler.

Added after 47 [seconds]:

EDIT: I can also see it has 5 transistors? So you can easily use it as RGBCW.

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:
