Thanks, steven r. I tried testing with RF calls, and indeed, they do not work at all.
Of course, the powerline invocation is not reliable either, or I wouldn't have asked the question!
I can see all of my "physical events" showing up properly on the Activity Monitor, but oftentimes my macro calls do not appear. AHP seems to be easily overwhelmed when asked to do more than one thing at a time. I have dummy modules
on my monitored housecode indicating the open/close status of each door. (The macros for the DS10A open/close events just turn these dummy modules on/off.) These dummy modules are in the proper state almost 100% of the time (so I think my RF is OK...). However, the Module Status in AHP is not always updated properly, and the macros called as a result of the dummy module turning on/off are not always executed. Sigh...
Currently, the OnAlert security macros turning my dummy modules on/off are the only things running on the PC. All of my other macros/timers/etc. are running on the CM15A. Everything I've read in the forums tend to suggest that this is the optimal way to set things up. I've tried toying with delays in my macros with no success. It seems that if a new powerline event comes in before all of the macros associated with the previous event are completed, system behavior becomes non-deterministic. I'll be happy to send my AHP file to anyone who wants to have a look, and I welcome any additional suggestions.
Without this forum, AHP would have been shelfware for me a long time ago, so thank you all!
