Currently in diy controllers (like renard SS16) and equivalent wired controller costs $80 with shopping around. Then to make it wireless requires an additional $10-30 depending on what you chose.
That is still a bargain compared to commercial controllers like Light O' Rama.
CTB16PC-ReadyToGO $259.95 + RF-V5-PAIR $249.95
So at $30 and wireless I plan to cheapen this little hobby that already costs way too mutch:) To my knowledge this will be the first AC diy controller to be wireless from the start.
The reason for going this route is that I spent a lot of time last year with komby(Greg) perfecting a related project using the same protocol, it ran perfect so doing it again. (also cant beat $1-2 for rf modules ) Also great excuse to expand komby's rfcontrole lib to incude AC leading edge dimming.
