Ray, thanks for the info. The RF solution looks interesting and simple to do however it is my understanding that it would void the warranty of the OS.
Also, I just placed an order for 3 OSP and 3 expansion boards however it said v. 2.1. Will I be getting the 2.2?
I am looking for an open face relay, do you think this one will work:
I believe this one is 24VAC..
