My Eaton Home Awareness kit just arrived. I got quite an assortment of parts for less than $50 to start playing with and hacking. What I got is the starter kit which includes the base stations, one home key, and one door/window sensor. Also a second home key and door/window sensor, a range extender, and the garage door sensor.
I am very impressed with the garage door sensor, and had one of those “why didn’t I think of that” moments. I have been struggling to come up with a good clean design to detecting if the garage door is opened or closed. All of my designs involved some type of contact switch, which I tried placing in various location and required a lot of tweaking and constant adjusments. The solution the home awareness kit uses is very clever. It employs a “tilt switch” that you just stick to the garage door. If the tilt switch is vertical the garage door is closed and if the tilt swich is horizontal the garage door is open.
