Do hubs make sense? Z-wave? Cloud services? Open-source solutions? SmartThings?
I'm having a very hard time figuring out what's a reasonable way to go about it.
Right now there aren't any systems that do it all well, so you want to just pick the best tools for each job, then glue it together with a hub.
A surprising number of things have relatively IP interfaces, so in my house I scripted it all together by writing http://route.io/ - this lets me do things like control Sonos from my lightswitches, unlock my house when I walk up to it, or turn off everything with a single command.
The best way is going to be a custom solution with hacked together custom hard/software. You can then open source your design for community learning and growth.
I use a VeraLite hub for two purposes: (1) to talk to z-wave things, and (2) because it provides one API for thousands of devices. Not everything will work with Vera, but most of the popular stuff does, from smart bulbs to switches to home security and cameras. Vera's hub doesn't have a monthly subscription or require a "cloud" to work. You can also buy one used for a reasonable price on Amazon/eBay.
Is there a significant lag between calling an action and it taking place? I've got a wink hub and it's hilariously slow at running scripted events.
For example I have it set to lower the bulbs over our kitchen table, bring up bulb over the sink and then dim a lamp at 7pm when we normally sit down for dinner. In theory this sounds like it'd be neat but it just dramatically drops the light output and takes about 20 seconds to go from one bulb to the next.
No, it's nearly instant most of the time with the wifi stuff (WeMo light switches, Nest, etc). My z-wave door lock sometimes lags a few seconds, but I blame that more on the protocol than anything. I exclusively use the hub for its API; I don't know if the built-in UI would have any lag when executing scenes created through that.

Here's a bit about my setup:
