That's pretty neat. Well, I never liked the software because for one thing, it would only manage one UPS and I have different devices for different power-hungry items so that seemed unusual. I suppose I should look at it again because it has that feature. Now is that included in the basic edition that is included with typical, consumer UPS devices? It probably wouldn't be tough to write a little application that would just monitor battery power and email on certain events but the APC software would probably be a good choice.
Oh and I never liked the shut down computer settings because, if I remember correctly, the available percentages for shutting down didn't go low enough. My UPS is nowhere near huge and can only run my server for 20 minutes...and it cost $200 (marked way down at purchase). To get 18 hours how much would it cost me?! And you're talking big time...my setup is just for home and I really don't care if things go down...not for the price it would cost me to keep them up! We don't have many power issues here anyway other than the very rare short power loss and that isn't any trouble for shorter lasting units like mine. It's a 1500 VA APC unit. I have two of them plus a 750, 725, 2 * 650, 2 * 350...so around 8 total UPS devices. The smaller ones are great for special items like cordless phones so they still work when the power goes out (the base station, obviously).
