It's not that far off when you consider replacing just light switches with Z-wave switches in a 2000-2500sq ft home. Figure there's probably 25-30 light switches in a house that size. You're looking at about $900-$1200 worth of equipment just to control just whole room lighting. If you went the Phillips Hue route, as an example, you'd easily approach that with 2-3 rooms worth of light bulbs. Add in control of individual outlets, motion sensing, thermal controls, security ... it adds up pretty quick, even for homes of the "middle class".
