I just had a look at some Z-Wave motion detection sensor and I soon remembered why I chose ZigBee some years ago: they’re soooo expensive! ZigBee sensors costs half/a forth if the Z-Wave ones!
Why that? Maybe for the more expensive royalty? More expensive components?
I believe that Z-wave is more open then Zigbee (although it didn’t start out that way, and it’s unclear to me whether it’s completely so now or not).
Thread exists because it’s meant to be the royalty-free replacement for both of them (and the first royalty-free standard since X10).
