C-Bus Application - 1 or 208 ?

[Nick Locke]

I am building some code (VB .NET. not that it matters) to interface to C-Bus.  One of the things I am doing is monitoring for events.  I need to work out whether it is better to monitor Comfort events on C-Bus application 1 or on application 208 (security).

So far as I can see, zone status changes appear pretty much the same on both.

I must be missing something, because otherwise we would not have the bespoke application 1, there would only need to be the standard 208.

What am I missing?

Thanks, Nick.
