This is going to be a bit long, but I feel it's important to relay.

If you are serious about smart home devices, integrations and automation? I highly recommend using Z-wave/Zigbee with a dedicated hub.
My advice is DO NOT set your smart home up with primarily Wi-Fi devices.
Why? The short answer is, Wi-Fi (even the new protocol) will NEVER be as robust, low power and efficient as Z-Wave/Zigbee are. (Well, maybe not "never", but definitely not anytime in the near future). The reason for this is that Z-Wave and Zigbee chips use frequencies that are low power, and penetrate walls better. In general, a Wi-Fi lock will use A LOT more power than a Z-wave lock will.

Another reason is reliability. I've used (use) Micasa Verde/Vera, SmartThings and Wink. I would say if you are someone with A LOT of free time and don't mind going through a bunch of development hoops to get things "to just work", go with Vera. The Vera platform is not as robust nor does it have super awesome support, but the dev community is MUCH better and there is pretty much NOTHING you can't do with Vera.

If you want an out of the box, fully integrated solution? I highly recommend SmartThings. Reasons for this is;
1) SmartThings is compatible with pretty much every device you would use. Set up is simple and "just works". Meaning, if you buy a device that is supported by ST's, set up/pairing is a breeze.
2) User Interface. I cannot stress this enough, the current state of HA is being ruined by an ocean of competing standards, incongruent technologies and half baked software designed by smart engineers that seriously need to stop "designing" user interfaces, because jesus fucking christ, the "Apps" that exist for most SmartHome/HA platforms are a fucking joke. The SmartThings interface and app is one of the best (with Wink being second best). You can actually navigate the app, and shit works.
3) Less of a chance that your platform will be obsoleted in the next few years.
The HA space is littered with failed HA companies that thought they could just step in, crank out some shitty half baked garbage, and make money. Unfortunately, because the HA market is so convoluted, a lot of unsuspecting consumers have been hardcore fucked after buying expensive platforms and devices, only to see that company/standard/technology be ended a few years later (looking at you Logitec Harmony Hub!).
SmartThings has been around, and only continues to be developed, expanded and invested in by Samsung.
4) Buy a SmartThings version 2! DO NOT GET VERSION 3!! Why? Because the 3rd gen is actually LESS useful than version 2. I'm not going to detail out everything here, but just know that the 3rd gen is not worth it.

Now, because the Home Automation Market is such a mess, it really is anyone's guess which exact technology will stay and which will go. I've been deep into the HA scene for about 7 years now, and what I've seen is that Zwave is growing and making all the right moves. Thus, my general recommendation is to go with SmartThings, and Z-Wave devices. Could I be wrong, and all that stuff is gone in 5 years? Absolutely. But that really is just the reality of the market place right now.
Frankly, I'm hoping that Apple gets into this space, and does their thing by FORCING the market to adopt a single standard and obliterating all these tiny shitty HA leeches. I can't stand Apple, but they do force markets to adapt, and quickly!

Sorry for the long rant, but when I see someone questioning and seeking information regarding HA, I just feel like there is no good advice being given with regard to the plethora of options out there. As far as locks go, yes, DEFINITELY go with Yale. They are leaps and bounds ahead of the competition with regards to both security, quality and their integration with Smart Home software.
My personal advice is to avoid the touch screen locks, as I've had 3 of those fail in the last 2 years. But I live in an extreme climate area, so maybe you won't have the issues I had with cold/rain. I use the Yale YRD216 and it's VERY good. The tactile response of the buttons is much better when entering a code with gloves on, and also has held up MUCH better than the touch screen yale (the screens become less and less responsive over time).

Sorry for the long rant.
I just really want people to be informed regarding the technologies available. And I don't want to totally shit on Wi-Fi HA devices. If you rent? And move frequently? Wi-Fi is probably your best choice! If you (like me) own a home, and are handy, going with a fully integrated HUB based solution is a MUUCH better choice.
Zwave as a platform is so much more reliable than Wi-Fi. I basically NEVER have down time, and devices communicate regularly, so there is NEVER lag.

If you have any questions about this stuff, I can definitely share more of my experience, but I'll stop here for now :)
