Do you have the whole shooting match (apologies to Dick Cheney) setup with the X10 outlets or are you just checking out the software?
There are quite a few people at RC who do stuff like this, although most of them go pretty hard-core, programming their own controllers and interfaces. I've heard that the X10 isn't terribly reliable and that sometimes won't work because of interference.
I'd really like to do something like this, but I'm going to wait until I own a home and can build an in-wall power panel.
Ha Ha!!!! Sorry, no I don't have the whole shabang yet, but am considering the hardware that they are adversertising on their sites. Just checking out the software for now. Ditto on the home ownership here too, but the prospect of a small module and a dedicated computer is pretty tantalizing.
There are a lot of different commercially-available controller boards for aquariums, but this one is particularly tempting to me because it uses off-the-shelf hardware. If you're interested, you might post the link on RC and I'm sure you'll get plenty of opinions and info on the competitors.
To be completely honest, however, I wonder how much utility these are for ceph-keepers, since our systems have a lot less we need to keep in equilibrium than reefers. If we see our pH changing from our office, we don't have kalk reactors we can turn on, etc.
I think techno-overkill might be the exact phrase to use, I tend to over do it a bit. The trial software version is for 30 days, and I'm going to keep notes, and see how it feels. I'll keep y'all posted.
