How to use new datatype RGB-W - gdimaria - 14.08.2020

Hi,

I already know how to use RGB datatype (by a little tutorial by schneider), so I can split the value to the 3 objects (Red, Green, Blue) and viceversa.

Now how I can do with RGB-white?

And I tested it on visualization but it seems to me a little confusion

RE: How to use new datatype RGB-W - Daniel - 14.08.2020

What is that you want to use it for? There is dedicated dpt for it and some KNX devices support it.

RE: How to use new datatype RGB-W - admin - 14.08.2020

Which browser are you using? The slider is not displayed correctly. Are you using zoom/scaling?

Chrome without any scaling... same on Firefox and Edge.

I just want to let the user to click on RGB-W icon to set it.

On the other side I would like to update the value when I set it with a script.

That's a ordinary conversion I do with a script for a RGB:

Write to RGB
----------------

Red = bit.rshift(bit.band(value, 0xFF0000), 16)
Green = bit.rshift(bit.band(value, 0xFF00), 8)
Blue = bit.band(value, 0xFF)

grp.write(redGroup, Red, dt.uint8)
grp.write(greenGroup, Green, dt.uint8)
grp.write(blueGroup, Blue, dt.uint8)

Read RGB
------------

red = grp.find(redGroup)
green = grp.find(greenGroup)
blue = grp.find(blueGroup)

redHex = red.datahex
greenHex = green.datahex
blueHex = blue.datahex

RGB = lmcore.hextoint(redHex..greenHex..blueHex)

grp.update(rgbGroup, RGB)

Now how I a can do the same with a RGB-W object, which is made up of 4 scale % objects: RED - GREEN - BLU - WHITE?

Thanks.

Hi,

Use this for 4 byte RGBW:

Code:
value = event.getvalue()

-- Split

R = bit.rshift(bit.band(value,0xff000000),24)

G = bit.rshift(bit.band(value,0x00ff0000),16)

B = bit.rshift(bit.band(value,0x0000ff00),8)

W = bit.band(value,0x000000ff)

-- Merge

RGBW = R * 0x1000000 + G * 0x10000 + B * 0x100 + W

I think there is a little mistake in that code because the colors shown by the icon don't match both ways: splitting and merging.

Hi,

Just tested it and works as it should, are you using dpt 12.600?

yes, I do.... and I use 05.001 scale for R, G, B and W.

Maybe it depends about when both scprits are enabled, they generate a sort of loop back.

Here are my script:

EVENT SCRIPT 'mergeRGBW'

R= grp.getvalue('32/3/1')

G = grp.getvalue('32/3/2')

B= grp.getvalue('32/3/3')

W = grp.getvalue('32/3/4')

RGBW = R * 0x1000000 + G * 0x10000 + B * 0x100 + W

if RGBW ~= grp.getvalue('32/1/20') then

grp.update('32/1/20', RGBW) --- icon address
alert (RGBW)

end

EVENT SCRIPT 'splitRGB'

value = event.getvalue() ---- from 32/1/20 icon address

-- Split
R = bit.rshift(bit.band(value,0xff000000),24)
G = bit.rshift(bit.band(value,0x00ff0000),16)
B = bit.rshift(bit.band(value,0x0000ff00),8)
W = bit.band(value,0x000000ff)

if R ~= grp.getvalue('32/3/1') then
grp.update('32/3/1', R)
alert®
end

if R ~= grp.getvalue('32/3/2') then
grp.update('32/3/2', G)
alert(G)
end

if R ~= grp.getvalue('32/3/3') then
grp.update('32/3/3', B)
alert(B)
end

if R ~= grp.getvalue('32/3/4') then
grp.update('32/3/4', W)
alert(W)
end

That's all. Still, there is a visualization issue like a reattach here

RE: How to use new datatype RGB-W - admin - 25.08.2020

See if this Custom CSS fixes the slider layout for you:

Code:
.slider-wrap {

  font-size: 0;

}

.slider-h .slider-min {

  margin-right: 9px;

}

.slider-h .slider-max {

  margin-left: 9px;

}

Add this to both of your scripts to prevent loops:

Code:
if event.sender == 'se' then

  return

end

You should also use grp.checkupdate() instead of grp.getvalue/grp.getvalue, you already have copy-paste errors where you compare R with all other components.

OK! Now everything is fine, thank you so much!

Just to a better understanding: what is the core difference between grp.checkupdate, grp.getvalue and grp.update?

Thank you for everything

See Lua documentation here: https://openrb.com/docs/lua.htm#grp.checkwrite
The basic idea is to write less code by using built-in functions instead of writing more complex code, which leads to more possible errors.

RE: How to use new datatype RGB-W - Erwin van der Zwart - 25.08.2020

Hi,

I think your issue with the merge is in the 5.001 scale objects as they return 0-100 within the script engine instead of 0-255, when you split/merge a RGBW value you will have 0-255 format so you might want to use a calculation R = math.round((R * 2.55),0) before pushing it to the merge calculation (and do the same with other 3 colors)

BR,

Erwin

RE: How to use new datatype RGB-W - Daniel - 25.08.2020

When merging it is better to use hex values as then it is dpt independent(still 1 byte). Updated the old RGB script, not tested Smile

Code:
------------------- Configurable parameters ------------------------------------

redGroup   = '1/1/1' --- modify ether group address or name of group

greenGroup = 'LED1 Green Status' --- modify ether group address or name of group

blueGroup  = '1/1/3' --- modify ether group address or name of group

whiteGroup = '1/1/4'

rgbwGroup   = 'RGB Value' --- modify ether group address or name of group

-------------------------------------------------------------------------------

red   = grp.find(redGroup)

green = grp.find(greenGroup)

blue  = grp.find(blueGroup)

white = grp.find(whiteGroup)

RGBW = lmcore.hextoint(red.datahex..green.datahex..blue.datahex..white.datahex)

grp.write(rgbwGroup, RGBW)

yes, I noticed it and fixed, thanks.

Here another issue with visualization (see attached pic): what are the black spot on preset? How to avoid that?

RE: How to use new datatype RGB-W - admin - 26.08.2020

Black spot is W value of RGBW

RE: How to use new datatype RGB-W - Daniel - 26.08.2020

This is the white status. Change the white value and it will have different colour

Ok sorry to not understood!

RE: Urgent! - gdimaria - 18.09.2020

Sorry, my script was working on the LM (firmware 20200720) in our office.

Today I restored it on a new LM (firmware 20200727) at customers' and it doesn't work and give me the attached warning.

We are blocked now.

Can you please help me?

Thanks

Paste the script as a code not image
