You can build a wired or wireless mosquito automation network which only talks on your home LAN using arduinos. Google the Homeseer forum for more information.
That said I would wire LV 16/2 to the automated blind locations anywhoot.
Here is a post relating to using HunterDouglas Powerview shades from a HS user on the AVS forum.
Hunter Douglas PowerView shades & blinds
I've got 15 of the new PowerView shades, in four rooms. It's a newly built house (no old materials or RF-blocking lead paint). It's 3 stories, including basement, with a mostly open floorplan.
The mesh RF setup is uneven, at best. But then I'm only a few days into owning them. I expected a bit of rearranging was going to be necessary. The hub (their RF-to-ethernet bridge) had to be moved up to the Master Bedroom (along with a Tivo, wired Chromecast, Amazon FireTV and other gear). I've got their repeaters in the other rooms. The repeaters are positioned such that they're in-between the shades for that room and the hub. As in, upstairs shades -> hub -> repeater -> 1st floor shades.
The initial experience is, to be kind, uneven. If I use the PowerView remote (the pebble) to manually join the shades to it that seemed to work. But in the master bedroom one of them has decided not to answer to the remote. Likewise, two of the five in the living room don't seem to want to respond consistently.
The app on iOS is not great. For one, it has NO SECURITY AT ALL. Nor does it have a non-editing mode. Right, so anyone with access to my WiFi network has the ability to do ANYTHING to the setup of the hub! Who the Hell thought this was a good idea? Ok, so that's BAD. But to make things worse, there's no read-only mode. So I can't put the app on anything accessible to anyone else in the house. At least not without risking someone accidentally making unintended changes to the configuration.
There's also no technical information accessible for troubleshooting. No way to tell the strength a given device has to the RF network. So placement of the hubs and repeaters is pretty much blind hit-and-miss guesswork.
