Hue ledstrip with RGB and Tunable white

[DanielB]

Add to user library:

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
end

You will need to map an event script to both brightness and color temperature values:

Code:

require('user.hue)
lamp_id = 123
bri = grp.getvalue('1/1/1') -- 0..100%
ct = grp.getvalue('1/1/2') -- 2000K..6500K
setBrightnessCT(lamp_id, bri, ct)

Thank you very much :-)

Now it works like a charm:-)
