PIR Night Only - how do I do this?

[ComfortGeek]

Hi there!
I wonder if you could help please?
I would like to set a PIR so it only triggers the alarm at night - but I can only see options for it to be \'PIR Away\' and \'PIR Away & Night\'.
This is because when we are away from the house in the day, we want to allow our pets to walk in this zone, but at night, we want the zone protected (pets are not allowed in the zone at night.  I really don\'t want to refit the pet friendly PIRs as all my PIRs are ceiling mounted.
How can I achieve this?
Kind regards,
CG.

If you are not using PIR Away, you can go to Security Types > zone types and change  the name PIRAway to PIRNight, and change  Away to Disabled and Night to Immediate as shown below
