@brettzky84
there is TONS of this on the Vera website, and many many folks are connecting them with a (serial I think) interface that you may buy and the plugin @Dwalt mentioned.
Hi @tbowmo, do you mind to explain a bit about the design? I'm interested with your design.
I will use these steps for removing voltage regulator, http://goo.gl/CsZaNg
So the design will be battery > external step up regulator (http://goo.gl/PFt99R - to stabilize 3.3v) > vcc pin ?
with these then I can use my first post design?
Thanks
