I have decided to try some Shelly Home Automation products and stumbled across the Shelly Flood Sensor.

Shelly Flood Sensor
Very cool little device and I while I won’t repeat the specs because you can look all that up at the link above I will tell you what I think is good about the device and what I think is bad about it.
Having a water sensor is pretty important in my estimation. While I’ve never had a pipe burst I did work with a guy once who deployed overseas for several months and his ice maker hose ruptured right after he left and leaked for MONTHS!
So I’m going to get several more of these now that I’ve worked through the installation of one of them. I intend to place them by the ice maker hose, the washing machine, under the sinks, in the hot water heater pan, and in the A/C secondary pan.
First I’ll start with what is bad about this thing. And I’ll pull no punches.
