I am using a PageMatrix and a Snapshot for zone selections.  The Snapshot is used to select all zones if "All Page" is selected or to only select a specific zone (unselect any other zones). To accomplish this, I had to make the paging stations button to a master control.  This all seems to work as desired.  However, I need to programmatically select "All Page" if the user has pressed an external button that I will connect via GPIO. Basically, I need the "All Page" button to be a Master for user input and snapshot and then also a slave to accept being controlled via code.
Will also need to use the PageMatrix with a DTMF.
I have attached a screenshot of the PageMatrix and Snapshot.
Thanks in advance for any ideas.

Some good ideas in there, Fergy.
I use the attached plugin for Vox PTT.

Wow...what a PageMatrix!!
I see where you detect presence or button press to select a source, so hopefully that will help with one of my issues.  I will work on this and get back with to you when I have more questions.
Thanks,
Owen
