my opinion: z-wave for lights only is not efficient - it mainly can give you dimming capability, no control over warm/cold lights or even color. plus everything is an unfortunate combination of wiring and rf. zigbee based lamps like hue or others are much better here. however, for controlling things like heating or blinds I find it very effective in combination with sensors. It is quite simple for everone to do simple things, like setting schedule based target temperatures. and reasonably simple for a dev to do complicated things, e.g. to control blinds based on exact position of the sun around the year. plus you can always use actuators that work without the base controller, so the base controller is just an option.
