This is very very very simple door alarm.
If you have cats, dogs, tigers, dragons, any pets that can run out if door left open you can use this.
Alarm won’t be triggered for normal use. But if the door left open over 25 seconds (you can change that) it will start and you’ll get an SMS message and sound will be played.
Reason for line 24 is:
I didn’t want to alarm to go off by mistake (somehow) while we are in bed. (the house alarm is different than this one)
pls tag me if you have any questions.
