What are you looking to accomplish?
Home control can be as elementary as being able to shut off a downstairs light from upstairs, but it can also be a sophisticated command center for virtually anything that runs on electricity in your house.  Tasks like multi-room audio and basic lighting control can be practically plug and play these days, while more elaborate schemes that integrate with your thermostats and security systems are best specified and installed by a professional.  Qualify your own goals before starting to shop.

Everything in this Florida home, including the pool temperature and outdoor lights, is operated by an AMX system.
