Hue Brightness feedback

[Sral1987]

I Tried this with no effect

Code:

--Control HUE from byte object (brightness) (use as event based script)
require('user.hue')
value = event.getvalue()  -- 1 byte unsigned integer scale 0 - 100
group_id = 1 -- change this ID to your actual light, see getHueLights() result for lamps or use your app to resolve them
setBrightness(group_id,value)

then i added a function in user.hue with also no luck.

Code:

function setBrightness(Group_id,brightness)
  if brightness == 0 then
      body_msg = '{"on":false}'
      response = sendToGroup(group_id,body_msg)
    return response
  else
    brightness = math.floor((brightness / 1) + 0.5)
    brightness = math.floor((brightness * 2.54) + 0.5)
    --HTTP request send
    body_msg = '{"on":true,"bri":'..brightness..'}'
    response = sendToGroup(Group_num,body_msg)
    return response
  end
end
