Run tunable white (HCL)

[tomnord]

Here's my version with linear transition. Values at 0:00 and 24:00 are mandatory, values in between can be added as needed.

Code:

function tomins(hour, min)   return hour * 60 + min end points = {   { hour = 0, min = 0, value = 2500 },   { hour = 7, min = 30, value = 2500 },   { hour = 8, min = 0, value = 3000 },   { hour = 9, min = 0, value = 5000 },   { hour = 16, min = 0, value = 5000 },   { hour = 17, min = 0, value = 3000 },   { hour = 18, min = 30, value = 2500 },   { hour = 24, min = 0, value = 2500 }, } now = os.date('*t') currmins = tomins(now.hour, now.min) for i, point in ipairs(points) do   nextmins = tomins(point.hour, point.min)   if nextmins >= currmins then     nextpoint = point     prevpoint = points[ i - 1 ] or nextpoint     prevmins = tomins(prevpoint.hour, prevpoint.min)     break   end end deltamins = nextmins - prevmins if deltamins > 0 then   delta = (nextpoint.value - prevpoint.value) * (currmins - prevmins) / deltamins else   delta = 0 end value = math.floor(prevpoint.value + delta) log(now.hour, now.min, value)

Could this be adjusted for use with two objects for warm and cold white?
