Aaron,
We started the website www.zwaveshades.com to promote our Z-Wave native motors in the final product. (still needs to be completed one of these days)
We offer some finished products in Florida as it is where we are located but we also have a fabricators in California,New York,...that are very knowledgeable in shading systems and Z-Wave implementation
Or ask Shady, he knows everything about Z-Wave shades

I'm in Colorado... you should make it clear on your web site where you are selling these. I'm still not clear, even from your post above if you will sell them outside Cali, NY & Florida?  And if you do, who should I contact? thx

I plan on outfitting my basement with these blinds.com shades in the near future. Instead of going the USB attached RS232 route, I decided I wanted to use something similar using relays, but that I could control over IP whether over 802.11x or ethernet. While I don't have the blinds yet, I have worked out all the issues and integrated a raspberry pi with an 8 channel relay that is integrating very nicely with the vera. I can see it triggering what will be the handheld shade RF controller soldered up to the relays.

Here is how I'm doing it.
I'm combining three different ideas from people much smarter than I.

A) 8 Ch Relay ($12) attaches to a raspberry pi A or B
 https://www.youtube.com/watch?v=oaf_zQcrg7g

B) Express-GPIO
This is an excellent piece of software that opens up a web server on the raspberry pi on port 3000 and takes http requests in order to control the pins, which in turn trigger the relays from the project in step A.
https://github.com/notsunohito/express-gpio

C) The Vera luup code tied to a scene (i.e. "Blind Up" "Blind Down" or whatever)
This is just basic luup code that I've used in the past to make http request for controlling vlc player, but it applies here.

os.execute('curl -g "http://192.168.1.XXX:3000/gpio/3/low/"')
os.execute('curl -g "http://192.168.1.XXX:3000/gpio/3/high/"')


Change the XXX to the IP of your Raspberry Pi on the network, and change the 3 to whatever GPIO pin you want to control.

All said and done, I have a scene that when triggered flips the relay on then off simulating a touch on the handheld controller

Only thing left to do is wire up the remote once I have one.

Benefits
-Relatively Cheap (Rpi B is 25-30 bucks, relay is $12)
-RPi can be used for other random uses in a HA system.

Benefits over the RS232 solution:
-8 channel relay ( can control 4 blind sets for up and down.)
-is not limited by the length of a USB cord.
-Can work wirelessly over wifi or for a more reliable solution, hard wired to the network. This allows better placement options if you plan on doing lots of blinds around the house.
-leaves usb port open for other uses.
-no plugins required
-very little if any extra overhead over normal scenes.
-You can build additional relays as needed

Drawbacks over RS232 solution:
-Requires a network to be in place in the home, but if you have a vera you probably have some sort of IP network anyways.

Other Drawbacks:
Still no feedback of what state the curtain is currently in. (might be able to guess with some sort of virtual device setup that relies on the last scene triggered, but thats beyond my current abilities)

Hope this helps someone and I will report back once I actully have blinds in my hands to test this on.
If anyone needs any help with the rpi software configuration I can help as well.

@cbutters
can you post a link to the blinds?
Did you look at doing ZWave, which would provide the status, i think?

Check Post #1 for a link to the blinds.

@Aaron What kind of zwave blinds did you have in mind? I can't really find a good solution other than something that adapts somfy, but even that doesn't give status if I understand the ZRTS module right. Which zwave blinds do you know of?

I have roll shades and 2" wood blinds... so the rolls need % up/down and blinds need % open/close

Looks like those cellular shades have a wireless remote? So how are you interfacing? Bypassing the remote? Tapping the motor wires in parallel? Please explain. thx

Can someone please post a picture of the battery connector on the Blinds.com items I am doing this project dont have the blinds yet but have prewired for power to the blinds I am guessing that its 8xAA so 12v if someone can confirm the battery count

Anyway I would like to connect the power without cutting so a picture or a connector name/type would help

Thanks
