Kwikset 914 Zigbee or Zwave Z-wave?

Last things first: any smart lock can fail to report to the Hub either because of a range issue, or because smartthings is being flaky,

Have you had a chance to read the FAQ on wireless range? Start with post 11 in that thread, read it, then go back up to the top of the thread and it should answer most of those questions:

As far as zigbee versus zwave, zigbee has been very popular with the expensive high-end professionally installed Systems like control 4, but those installers have a lot of network mapping tools that we don’t have with SmartThings.

For those using inexpensive DIY systems like smartthings, in the US Z wave has definitely been more popular for fixed location Devices like locks and light switches. It’s just easier once you take Wi-Fi interference out of the picture.

The lock that I had was a high-quality lock that worked fine with SmartThings for over a year, then it started opening randomly for about three weeks, I took it off of SmartThings and put it on Wink and it worked fine again. I moved it back to SmartThings and again it started randomly opening, moved it back to Wink and the problems went away. It wasn’t the lock model causing The issue, so I don’t want to list it and create any kind of negative for that particular lock. It wasn’t the lock. :wink:
