Since you didn't specify the particular KIND of automation you were seeking, I provided some alternatives for BOTH home control AND computer control.
Hal isn't quite up to the task of automating my home via X-10, Zwave, etc. at the present time. Perhaps in the future but that's a way off.
There's also a program called Girder to allow for control/ automation.
I know a lot of plug-ins have been written for Hal to do various computer related tasks but again, Hal's current state was and is as a conversational assistant. There are some other alternatives in this area: One so expensive and still trying to come to grips with commands and searches and not worth the high price IMHO. Another avenue might be to look into one our member's creations / extensions of Hal. Halwindowscentral.com I think is / was the web site.
Hal is great for remembering things, events, appointments, calendar dates, etc., but not quite there for sending/receiving emails, searching your computer for a file or song, etc. Hopefully, soon.
Good luck!
