Alarm "clock" - FatMax - 29.08.2017
I´ve tried finding a solution for setting an alarm time to i.e. progressively increase the value of a light in a period of time.
Having difficulties wrapping my head around the os.time/os.date function.
Has anyone done something similar with a working solution?

Thank you for the reply.
The reason I mentioned os.time/os.date is because i dont have a set schedule. This means I´m not interested in waking up at the same time every day of the week (some things can not be automated easily). I want to set a time in visu that then will trigger the wake up light 30 mins before that time.

1/1/1 = time object
1/1/2 = output object
delta / 10 controls how smooth the transition is, 10 means 10 * 100 seconds to get from 0% to 100%.
Note that this will not work correctly if alarm is set very close to after midnight.
This can either be a resident or a scheduled script, depending how long the final transition is.
Code:
function getoffset(t)
return t.hour * 3600 + t.min * 60 + t.sec
end
now = os.date('*t')
now = getoffset(now)
set = grp.getvalue('1/1/1')
set = getoffset(set)
if now <= set then
delta = set - now
val = math.floor(100 - delta / 10)
if val > 0 then
grp.write('1/1/2', val)
end

This is fantastic.
A question on the side; the time object, is it a 3-Byte object? How do you write the correct values to this in a script?
RE: Alarm "clock" - admin - 29.08.2017
Yes, 3 bytes with type time/day
