You can create a virtual switch device then set an Off delay of the desired time. After you turn it on it will turn itself off after it's reached the time for it's off delay. You can then trigger on the virtual device change.

You can check the "last modified status", this has a date/time in it. Compare the date/time against the current date/time and you know the time difference. Do this in a time based Lua script.

I do what you need with SET/AFTER



The rule do this:
If door or windows = open then wait 15 sec and turn on the Siren (This give me time to deactive the alarm)
If Siren = on then turn ON living room light for 5 minutes / turn it OFF SIREN after 5 minutes

ok, think i getting the hang of it,
however,

is it possible to make:

if door =open then countdown
if countdown>0 and <30 and pushbutton=on then stop countdown and deactivate alarm
