Can I use an Aeons Lab Z-Stick in addition to my ST hub?

I would look at @scottinpollock 's HAM Bridge first.

HAM (Home Automation Macintosh) Bridge Goes Beta

HAM Bridge is a Mac app that lets you execute scripts (AppleScript, Automator workflows, Shell and Python) by issuing a simple HTTP GET request using a single parameter. You can check it out now via my G+ community. Over the weekend I will be posting a SmartApp or two that will send commands to the bridge on your local network based on various SmartThings triggers. enjoy
