How to Simultaneously Use White and RGB on RGBCCT LED Strips via Openbk?

Hi,
I have an RGBCCT LED strip and would like to use white / cold white and RGB at the same time via Openbk. The background is simply that white is much brighter than RGB and I find this mixed with individual RGB channels best for my setup.
However, I can only achieve this state by adjusting the RAW channels under "Status". How can I use the channels simultaneously without going through "Status"?

Thank you for your interest in OpenBeken.
Simultaneous cold/white and RGB mode is not normally supported in Tuya products. Both LED drivers and LED strips may not be designed for the higher power consumption caused by using them in a way not anticipated by the manufacturer, and as a result they may become excessively hot and shorten their lifespan.

Did this strip support simultaneous RGB and CW modes in the manufacturer's application?

Although, if you want to use OBK in this way, you can write values to the channels with the following commands:

this will set the PWM channel to 50%.

Also you can set this via MQTT, via:

with payload equal to the channel value.


I am not sure, however, if this is exactly what you were asking. Make your question more specific and I will try to help you better.

Hello,
First of all, thank you very much for the very quick feedback! As always you do a mega cool job with the openBK project, thanks for that!

Yes, exactly I would like to be able to use all channels at the same time. I need the CW/WW for the brightness and RGB for the colours.
I don't really like operating CW/WW alone without another RGB channel and I never have CW/WW above 25-35%.

But now I understand why it is designed like this and I am still happy to be able to use it with all 5 channels!
My setup runs with Homeassistant, where I have integrated the openBK devices via MQTT. I basically only operate the LED strips via scenes, i.e. previously selected combinations for RGB, which I can switch with one click. This works really well with RGB, but not with RGBCCT. Like openBK, Homeassistant recognises that simultaneous operation is not normally supported.

My question is how I can still get Homeassistant / openBK to save the status of the channels as a scene.
I have created an animated gif to illustrate my problem. There I set my desired configuration in openBK (with RGB and WW) and then try to save it in HA and load it again from there. As soon as I press Save in HA, the WW channel (channel 5) is set to 0. (GIF is animated, please view original, as the animation is not played here in the forum)
