I haven't had to go into any of my electrical boxes to reset stuff. If the switch needs to be reset, it can be done directly from the switch without having to remove any cover plate once installed.
For my home automation, I have sensors (motion, door contacts, etc) on Zigbee and lighting on Z-Wave. The Zigbee sensors tend to be faster than Z-Wave devices, with the switches being about the same speed (in my experience).
However, don't forget the MOST IMPORTANT RULE of home automation:
- Anything you do has to pass "The Wife Test"
