People have been talking a lot about this lately, and there are a lot of standards and platforms out there.
I haven't personally chosen one system just yet. I'm waiting for the dust to settle around some of the newer stuff.
Before we get into specifics about implementing Lockitron with one system over another, let's talk about this at a bit of a higher level. I say we set some goals, review the tools we have available, and then come to a solution later.
Right now, the best tool at our disposal here is the Lockitron API. If you're serious about getting things talking, then I definitely recommend getting access to the V2 of the API. (@david, @cameron, @pmg, I don't know what the best method is here for people to sign up. Let us know.)
The API is open enough that you should be able to tie it in somehow, and failing that, most of these newer HA systems talk to IFTTT in some way.
Now let's set those goals I was talking about.
To help figure this out, let's answer these two questions-
1) What systems do you have in place right now? If you don't have one yet, what are you going to use?
2) What is the number one thing you'd like Lockitron to do with this system?
I'll start here.
1) Right now I'm working with OpenHAB on my Raspberry Pi, but I might just get a VeraLite.
2) My "going to sleep" scene confirms that the thermostat is set correctly, that any doors/windows with sensors are closed, and that all the lights are off. At the same time, I'd like it to confirm that Lockitron is indeed locked, and if not, to lock it for me at that time.
How about you?
