Bug in computation of colour temperature?

[LiSongMWO]

On the line here:

kelvin/huelight.go

Line 295 in 712f498

return int((float64(1) / float64(colorTemperature)) * float64(1000000))

If you pass 6500K the result of the computation will be 153.846153846 which will truncate to 153 due to use of int(). According to here the range is 500-154. So 6500K mapping to 153 would be out of range

Hi Emily,

thanks for reporting this. The official documentation at https://developers.meethue.com/documentation/lights-api (sadly behind a login) states

connected lights are capable of 153 (6500K) to 500 (2000K).

Kelvin is implemented in regards to this official specification as close as possible.
