If I’m reading things right you can get in on the $30 early bird yet for the wireless, which is schedule to ship in Feb '13. Realistically, as with all KickStarter projects, I’m mentally adding three months to the time frame.
19 days to go for this project. There’s some confusion over the different options here because he made some changes to the plans after the project started and of course KickStarter limits what you can edit or revise. (After all, you don’t want a project manager revising a reward and taking away some of the benefit!)
Pledge the $50 amount and you get a filter that will work with SmartThings.
