Yesterday I was upstairs cooking breakfast, I got a SmartThings push notification and simultaneous SMS with four words you don’t want to see: “Water Heater is wet”. I turned off the stove, ran downstairs to my laundry room and saw my water heater output flex hose spraying water vigorously onto the wall/floor/surrounding appliances. I shut off the supply, grabbed some junk towels and mopped the 1/8" or so of water that had collected in the area. Crisis averted!
There were a couple other fortuitous events that conspired to keep this from becoming a bigger issue, including the fact that I was working from home and could respond immediately. But as I wouldn’t have normally been in the laundry room during the day, and couldn’t hear the leak from where I was, the damage would have been much more widespread by the time I noticed it.
My setup is far from elaborate, I have some door/windows sensors, locks, lighting, smoke detectors and a Utilitech (Made for Iris) water sensor all running through SmartThings. Although my wife has been annoyed in the past by spurious notifications and endless tinkering, I think HA just won a place in her heart this week!
