The OnAlert plug-in runs 100% from the PC so there will be a noticeable delay in macros that are triggered by security devices.
Because of the way AHP interfaces with the security modules there is an extra step or two in the conversion to standard (non security) x10 commands.
It is kind of like using phantom modules to trigger macros!
The only way to decrease this delay is not to use security modules to trigger the macros that you wish to activate quicker!
There are mods to convert standard x10 motion sensors to door window sensors available on the web!
