Alarm "clock"

[admin]

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
end
