Security Update - IoT Belt & Suspenders 17Jan20

I finished modifying and installing some IoT tilt sensors on my garage doors. I chose Z-Wave Plus (the most secure) models which came with mechanical tilt switches on board. The mechanical is on the right in the 1st pic below. I'd heard the mechanical switches were prone to fail after a year so I bought a bunch of mercury switches from China and modified the sensors to use those instead. Both doors are monitored now and the system works great. It's belt & suspenders because my Arlo cam in the garage already monitors for movement and triggers when the garage doors go up. Now I am doubly sure if something is messing with my garage (and I'll have an image of them).
