How to use new datatype RGB-W

[gdimaria]

It's very strange: when I pickup a preseted colour (I preseted 6)  everything is working fine.  If I choose a color from RGB Palette, it returns a wrong color.

Can you help me?

Here are my RGB Scripts:

--- mergeRGBW ----

if event.sender == 'se' then
  return
end


IndRichiesta = event.dst

len = string.len(IndRichiesta)

suffisso = string.sub(IndRichiesta, -(len-5))

--log(IndRichiesta)

R = grp.getvalue('11/4/'..suffisso)

G = grp.getvalue('12/4/'..suffisso)

B = grp.getvalue('13/4/'..suffisso)

W = grp.getvalue('10/4/'..suffisso)


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


grp.checkupdate('40/4/'..suffisso, RGBW) --- icon address




-------   splitRGBW   ----- 

if event.sender == 'se' then
return
end

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)



IndRichiesta = event.dst

len = string.len(IndRichiesta)

suffisso = string.sub(IndRichiesta, -(len-5))



  grp.checkwrite('11/3/'..suffisso, R)

  grp.checkwrite('12/3/'..suffisso, G)

  grp.checkwrite('13/3/'..suffisso, B)

  grp.checkwrite('10/3/'..suffisso, W)
