Aaron have you thought about adding 1-wire support to Vera? I ran across this site that has done on the Asus router: http://www.dunkkis.org/
While thinking on how few sensors available for z-wave, I ran into 1-Wire, yet again, just to realize how useful and attractive it looks in LUA capabilities context. Temperature, humidity, whatever-you-want sensors easely integrated with Vera… a dream!
So, yes, it’s wired, which usually makes me think “WTH?”… But if RS232 over Ethernet is said to be doable, it all comes to local in-room wiring, and plugging it into another router, which would map its RS232 ports to Vera over WiFi.
Now, question to MCV - what are odds 1-Wire with some kind of over-wifi connectivity will be supported in Luup-ed Vera?
UPDATE: this can make things quite easy, a bit on expensive side though…

As far as a remote serial port, in this thread: http://forum.micasaverde.com/index.php?topic=1340.0 I posted the source code for serial proxy–it’s actually an app from SourceForge we modified. The cheapest wireless 1-wire interface I can imagine building is to get an access point that has USB and runs OpenWRT (probably <$20 on ebay), add a cheap usb->rs232 cable and an rs232->1-wire device (which afaik are really cheap).
I like 1-wire because there are so many sensors and they’re really affordable. I once used the 1-wire I-Button’s (little ID devices you can put on a key ring). I think the buttons were only a couple dollars, and the reader wasn’t much more. And then you had a really cheap secure entry system. To implement a low-voltage dimmable light, I used a 1-wire potentiometer that cost something like $3. The temperature sensors are around the same price.
Great news!
For those uninitiated in building OpenWRT optware - is there any guide or a resource to ease the learning curve?
If there was an easy way to take that $20 access point and turn it into RS232 and Ethernet proxy/bridge, it would open quite enormous possibilities.

This is great I have a couple of the n DS9490R lying around with a bunch of DS18S20 temp sensors. Time to start playing around a bit with LUA. I saw sourceforge also had a linux 1-wire driver today…
The 1-wire Luup device will have the same parent/child relationship as the Somfy blind controller walkthrough I did which is a step-by-step how-to for a Luup RS232 plugin device: http://wiki.micasaverde.com/index.php/Luup_Somfy_Walkthrough
Found very educating blog post, not directly related, but having many tips of working with OpenWrt, and containing some great ideas useful for integration with Kill-A-Watt…
Still would appreciate any info/tips from MCV et al on building serial proxy for openwrt platform…

Uh-oh, I started reading the post above, clicking links there and just noticed it’s morning already… :
