When it comes to home automation X10 is pretty much the standard protocol. You can connect all kinds of modules to all kinds of control stations and even build your own modules. Hack a Day shows a DIY guide to build an engine to remotely (or automated) open and close your blinds. It looks like a lot of work and you probably could use some technical know-how but nothing beats a home brew X10 module. If do-it-yourself isn't your cup of tea you could browse Amazon for all kinds of modules and starterkits.
