Initial scenes help

I just received the fibaro motion sensor and the zipato siren.
and now it’s about time to start building my home security scenes.
I’ve been following the PLEG guide and I would like to get some help with the following topics:

1 - How to correctly configure the house modes?
2 - How to tell vera we’re at home/away/vacation (2 android devices)
3 - Any PLEG code for common tasks to get me started quickly

Thanks!

Read; PLEG Basics - An Introduction to the Program Logic Event Generator by @RexBeckett. It includes numerous example scenarios.

Another forum member, @petewill, made a series of YouTube PLEG Videos - Getting Started with PLEG and Conditions if you prefer that format. But @RexBeckett’s writeup is the best starting point.

This is the guide I’ve been covering.
I would like to see some real-life PLEG code related to motion sensor and siren.
and getting some info on Andorid, Tasker and house modes configuration.

Thanks
