RGB control with device type 6 drivers

[admin]

For the strip lights though we are far off and we can't make much of the colours. For example yellow is light green and white is light blue.

RGB LED strips cannot produce accurate whites. You can apply scaling coefficients to make a certain color less bright to make it a bit more accurate.
Change the coefficients (0.9 and 0.8) as needed:

Code:

value = event.getvalue()
r = bit.band(bit.rshift(value, 16), 0xFF)
b = bit.band(bit.rshift(value, 8), 0xFF)
g = bit.band(value, 0xFF)

grp.write('1/1/1', r)
grp.write('1/1/2', g * 0.9)
grp.write('1/1/3', b * 0.8)
