Philips Hue Tunable white - Karaffe - 30.01.2022
How do I get it out that I can change the color temperature by a percentage value, either via the absolute color temperature 7,600 or via a 4-bit dimming step 3,007
with this script.
Can someone help me, I'm a complete novice
Code:
function setBrightnessCT(Light_num,brightness,ct)
if brightness == 0 then
body_msg = '{"on":false}'
response = sendToLight(lamp_id,body_msg)
return response
else
brightness = math.floor((brightness / 1) + 0.5)
brightness = math.floor((brightness * 2.54) + 0.5)
ct = math.floor(1000000 / ct)
ct = math.min(500, ct)
ct = math.max(154, ct)
--HTTP request send
body_msg = '{"on":true,"bri":'..brightness..',"ct":'..ct..'}'
return sendToLight(Light_num,body_msg)
end

You need an event script mapped to the color temperature object. Then you can call this function like this, replace 123 with your light number and 1/1/1 with the brightness control object address:
Code:
light_num = 123
brightness = grp.getvalue('1/1/1')
ct = event.getvalue()
setBrightnessCT(light_num, brightness, ct)RE: Philips Hue Tunable white - Karaffe - 01.02.2022
I've now tested the whole thing.
but get the message.
User script:5: attempt to call global 'setBrightnessCT' (a nil value)

Make sure you have hue user library and add require('user.hue') to the beginning of your script.

Anyway to control from Mosaic 3.0 Hue RGBW-ledstripes with color temperature and RGBW?
