simple noob question

I like control4 very easy not ridiculously expensive, although not cheap. Easy to find on web.

Im currently using insteon, is cheaper than other and gets the job done, in my current setup Im using Insteon for lights and fans, global cache to control tv, dish and AVR, and Aprilaire thermostat, everything controlled by Elve

JP hits the target pretty much right on with his choices. They give you a robust capability with reasonable economy.

My personal preference is Z-Wave over Insteon, but that's just my choice. One area of caution is that if you don't have a neutral in your switch boxes, you probably need to look at Z-Wave as they have dimmers that don't require a neutral. Insteon needs a neutral as does UPB.

Elve is a great choice. It's very robust in capability, yet simple to program and very economical. Probably the lowest cost of any of the serious players. Very strong support.

+1 on insteon, beware of what others say with regard to needing a neutral at EVERY electrical box, this isn't entirely true, while a neutral IS necessary for communication, they make two component kits that allow for retrofit control of lights when there isn't a neutral at the existing switch.

I highly recommend the ISY 99 by universal devices to go with any insteon installation, it will give you the iPhone control you're looking, makes set-up much easier, allows for timers, programs, etc. and a multitude of other options.

I think the neutral issue depends on how much extra effort one is willing to go to. Myself, I just want to replace the existing switch with a dimmer and not make any other changes, especially if it's something that has to be done at the fixture.

I've used a mi casa verde (z-wave) unit there is no monthly fee although the unit is more pricey to start
