I've seen articles in magazines about home automation systems that can control heating, air conditioning, security and other wiz-bang things. Can HCA control these sorts of things?

[HCA Admin]

Yes and No. HCA can control anything that can receive Insteon, UPB, or X10 powerline signals, or IR commands. HCA can receive from anything that generates Insteon, UPB, or X10 signals. Don't be fooled when you read articles about home automation in to thinking that with the correct software (HCA or anything from anyone else) you can live in a Bill Gates like mansion. There are devices that you can add to your home that are very capable - but without the proper hardware, HCA (or software from anyone else) can't control even a lamp.
For more information on what HCA can control, see the Features (http://www.hcatech.com/index.php?sid=features) section of the site.
