Understanding timed scripting

[FatMax]

I´m having some problems understanding why my tried timers don´t work as I want them to.

I have these two scripts, in two scheduled scripts:

Code:

-- Trigger
trig = '3/5/7'
-- set 100%
max = '3/5/6'
-- store scene
lagre = '1/4/5'
-- get scene
hent = '1/4/6'
--status
status = '3/4/38'
-- locking PIRs
PIRlock = '1/3/19'
-- find required object
obj1 = grp.find(trig)
-- object exists and current state is "on"
if obj1 and obj1.data then
grp.write(lagre, 0, dt.uint8)
grp.write(max, 100, dt.scale)
grp.write(status, 1, dt.bool)
grp.write(PIRlock, 1, dt.bool)
-- delta is in seconds
delta = os.time() - obj1.updatetime
-- switch off when timer expires
if delta >= 60 * 60 then
grp.write(hent, 128, dt.uint8)
grp.write(status, 0, dt.bool)
grp.write(PIRlock, 0, dt.bool)
end
end

The first one is to trigger 100% lighting for one hour, for cleaning purposes. It also locks the PIRs, saves the lighting state before setting 100% and sets a status object so we know it is in play.

However, when I activate the script, everything just goes to 100% immediately. If i try to put it in a normal event script, nothing happens when I push the button....

Code:

-- group address or name
addr1 = '3/5/8'
addr2 = '1/1/50'
addr3 = '3/5/9'
-- find required object
obj = grp.find(addr1)
-- object exists and current state is "on"
if obj and obj.data then
grp.write(addr2, 28, dt.scale)
grp.write(addr3, true)
-- delta is in seconds
delta = os.time() - obj.updatetime
-- switch off when timer expires
if delta >= 6 * 60 then
grp.write(addr2, 22, dt.scale)
end
if delta >= 12 * 60 then
grp.write(addr2, 16, dt.scale)
end
if delta >= 18 * 60 then
grp.write(addr2, 10, dt.scale)
end
if delta >= 24 * 60 then
grp.write(addr2, 4, dt.scale)
end
if delta >= 30 * 60 then
grp.write(addr2, 0, dt.scale)
grp.write(addr3, false)
end
end

This last one is for slowly dimming down the lights in a kids room. However, when I activate this script, whenever the lights is turned on normal, it will always dim down and go dark after a while....

What am I missing here..?
