With respect to the goals, that is the reason I selected the brands I did, including HE. However, I anticipate that I won't be able to adhere to that goal for every device AND I am not totally clear on the vulnerability of Z-wave/Zigbee devices. Admittedly I may be a bit paranoid on this point but I prefer not to take the risk if I can avoid it. As for the security monitoring service, that is where my current thinking is. Therefore, I have started to think about what devices I want to have monitored, e.g. perimeter devices (glass break, door open) and fire/head devices vs. those that I want to be informed of, e.g. motion and water leak sensors. Motion because that would mean a perimeter breach and water leak because they would automatically shutoff the water once a leak was detected.
