Ok, here is a short one. The home automation systems, like Simplisafe, have provided water sensors for a while now. What good is that if you are in Florida and you get a water leak? Well here is an evolution of the simple IOT (Internet Of Things) engineering that is very cool to solve that problem.

 

Its a device that simply clamps onto your water pipe and will turn off the valve if there is a water leak detected!

I have seen variants of this but this one is very simple and integrates with many of the home automation systems out there. I may get this just so I can walk into the cabin and say "Alexa" turn on the water :)
