RGBW - One Color Strip - *solved*

[amurray85 9]

Hey Guys,

Quick one for you guys i'm sure.. i've got an RGBW module connected to a white light strip (1 color only). It seems to RGBW module is trying to cycle through dif colors etc so the light doesn't appear to stay on the whole time. even if i choose white color it still goes on and off etc and isn't consistently on. Any advice? i'm sure its a parameter somewhere or something

Hi @amurray85

Could you indicate how it is physically connected up to the strip ?

 

Thanks

Hey @AutoFrank here's a photo.. if I adjust the color it comes on.. weird

Hi @amurray85

Have you tried connecting the strip to the W output ?

I've never used a white strip, they have all been RGB and I just use those outputs ..

Frank's suggestion is correct.  Where I use WHITE only strips, I connect to white and it works perfectly for me

[petergebruers 1,268]

I don't disagree with the others, connect strip to White terminal, but the 4 channels are identical. It doesn't matter which one you use, but of course the colour wheel doesn't work as expected if you use another channel.

 

All channels are protected agains over-current, over temperature, it's a very robust device, so I'd consider a faulty RGBW as last possibility. If you exceed its ratings, I think it shuts down until you turn it on again, so that wouldn't explain a kind of flickering.

 

A software/parameter issue seems unlikely to me. Unless the device is responding to something else on your network. For instance: if it receives an "alarm frame" from another module. See parameter 30. Alarm of any type (general alarm, flood alarm, smoke alarm: CO, CO2, temperature alarm). Default is off, so it doesn't seem likely... Do you have any script that sets it to a program instead of RGBW values?

 

It sounds like a power supply fault or a bad connection. When you connect the LED strip to the supply (so W wire to GND) - is it stable?

 

Can you film the blinking or flicker? Or describe more in detail? What's the on-off time?

Hey @petergebruers its not so much of a flicking but more like it cycles through the color wheel. It isn't staying on white. I've tried it connected to just the W output and it does the same thing. If i change the colors around and get it back to W the light comes back on but the device isn't remembering to stay on the White setting in the color wheel

Might be Parameter 8 that is wrong?

 

can you list your parameters for a single light device?

@amurray85

I set this up on my desk same settings as you and the only way I could get it to do what your saying is via GUI turning on "aurora" or one of the other RGB presets.

On the toggle switch it worked normally.

And just adjusting that one output it worked normaly

You want to use push button momentary switches on these, much better if you want to dim

i'm using a scene to turn this one @Jamie mccrostie - when i do it just doesn't turn on

but when changing the preset it than turns on.. any ideas?

No, it's not caused by a parameter. All my parameters are at their default. No issues with 3 x RGBW module. Never heard of it being caused by a parameter either... I'm using Lua to set RGBW values, I am sorry, I can't help you with block scenes.

[Jamie mccrostie 82]

I just did simple test block

scene with strip turning on with another light all works ok

@amurray85you might want to post your scene

I'm not saying this explains everything.. But you probably want to use "Set W" (or "Set R" or Set Color") instead of "Turn On". Because "Turn On" simply restores the previous state, it does not force a certain level...

 

An RGBW module has FIVE multilevel channels:

 

Four analog outputs: R,G,B,W channel:

 

0 = off

1 = lowest level = 0.4 %

255 = highest level = 100 %

 

The 5th channel is a dimmer (not "W" but "brightness", the 5th slider).

For dimmers in general and the RGBW dimmer channel is no exception:

 

0 = off

1 = lowest level = 1 %

99 = highest level = 100 %

255 = previous level = same as "turnOn"

 

The "dimmer" channel is the one that responds to "turn off" and "turn on" plus lua "getValue" and "setValue".

 

If you set a dimmer to "100" it will silently go back to "99". If you ever compare set and get value, this might confuse your program logic.

99 = highest level = 100%

255 = previous level = same as "turnOn"

 

 

Peter when you say "set w ", how do you distinguish between colours

The four channels are independent, W is the name of the fourth channel. It has no meaning. You might as well connect 4 x RED LED strips to the RGBW module. The OP has a white strip connected to "R" or he has followed our advise to move it to "W", am I right?

 

If you have an RGBW strip, you use "W" to control the pure white strip.

 

If you want to set colour (I really should say: values) on all 4 channels, use "Set Color" and enter 4 values for the four channels in one go.

 

If you want to set your RGB strip to a nice colour, say "emerald forest" because that's what you like, then VARY brightness without changing color, then you might be interested in the HSL colour space.

 

If you want to toy with hue, saturation and lightness (brightness), I can recommend a topic in which I present some math to work in HSL colour space.

Gents, i've solved it so thanks for all your input! you guys are brilliant

turns out that simply setting the device to 'on' isn't correct.

I had to set it to the desired output which in my case was "Set R" with a value of 100 for brightness

 

Thanks again guys - you guys rock

99 not 100

Im still disipointed you let that UBS  beat you

Your posts regarding RGB(W) levels made me rethink my previous post. I was mixing the W and brightness stuff. I've corrected my post with this information:

 

An RGBW module has FIVE multilevel channels:

 

Four analog outputs: R,G,B,W channel:

 

0 = off

1 = lowest level = 0.4 %

255 = highest level = 100 %

 

The 5th channel is a dimmer (not "W" but "brightness", the 5th slider).

For dimmers in general and the RGBW dimmer channel is no exception:

 

0 = off

1 = lowest level = 1 %

99 = highest level = 100 %

255 = previous level = same as "turnOn"

 

The "dimmer" channel is the one that responds to "turn off" and "turn on" plus lua "getValue" and "setValue".

 

If you set a dimmer to "100" it will silently go back to "99". If you ever compare set and get value, this might confuse your program logic.

If I have not misunderstood the question so is the question, how to connekt a white LED list to an RGBW module.
The image from amurray85 shows that his RGBW module is incorrectly configured.

The module should be configured as Output / Input and not RGBW or RGB.
Then you can easily fade four separate white LED lists.
There is no difference in to fade four lamps or four white LED lists.

I do exacly this in my greenroom.
