First call XHome services and see what they recommend.
Gee Robby hope u put more effort into life than answering this question.
The XHome service phone support is better than waiting for an answer here.
The way Comcast has the system now, you can't. You have to have a tech out to do it. You use to be able to get to the tech screen with the passcode of 1234, but that no longer works. You can't do anything with the sensors now except change the order in which they show up.
