ZWave has been working fine for me for 6 Mo w/ Pluto technology as control. But I can't find some of the other devices I want (no sprinker controller, no simple remote contact closure gadget (I can fake one easily but. . .) the thermostats for ZWave are expensive and the ZWave seems an afterthought. etc. But Zigbee is much worse, Insteon has only one supplier so far etc. The adventures of being a pioneer.
