TheA2Z,
Thanks for the incite, Yes this would be outside, and I agree there are a few options. I did try Zooz ZSE29 and had to return it because I couldn't get it to connect to eisy. It connected at first, and then I dropped off, and no matter what I did trying to connect and disconnect it, I could never get it to work. I spent hours and finally threw in the towel and sent it back.
I'll look at the Zigbee now.
