I have had an uncannily similar project to SwitchMote brewing in my mind for a while now, and finding SwitchMote is a big inspiration. My project basically replaces the 3 pushbuttons with a motorized fader, and the solid state relay with a triac-based dimmer.
I would love to beta test SwitchMote, and either way I will probably still be buying a few of your SwitchMote kits. I'm an Android developer and look forward to designing a SwitchMote app too.
