RGB control with device type 6 drivers

[gdokimov]

Well this is question to DALI manufacture, they implemented this object, we are just sending values to it. We are sending them based on KNX specifications.

Sorry but I don't understand how changing the data type from 3 byte 232.600 colour to 6 byte 251.600 DALI RGBW is supposed to solve our problem.

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)

Thank you! The scaling coefficients really helped. We thought that the problem come from the DALI driver type and not from the RGB LED strip.
