Highly versatile, perfect for hot attic use
I needed two water sensors to monitor the HWH and A/C evaporator drain pans in my attic which can get as hot at 130+ deg F in the summer. So that ruled out all battery-powered sensors as the battery limits them to ~100 deg F, and converting other ones to battery operation by fab'ing a dummy battery wired to a DC power source I found very challenging. These Fibaro water sensors are actually designed for running off a direct power source (allowing a 15 deg F to 130+ deg F operating range) AND have the ability to use an external wired sensor. The external power source was $5 and the remote sensor wire (doorbell wire) was $0.75/ft. And these have a super handy terminal strip for both connections. They paired easily with my Smartthings hub and tested out well. They also provide the added benefit of giving the exact temperature in my attic, key information to have when temps drop below freezing and you've got water pipes in the attic. For my use case, this was the perfect solution.

4.0 out of 5 stars Instructions are incomplete
Reviewed in the United States on September 8, 2022
I like how easy this was to integrate with my Smart Things hub. But when I tried to use it with a DC power supply, there were two issues not mentioned in the instructions:

1. There is no opening for the wire. I had to drill one in the top of the case.

2. It doesn't sense water if the battery is inserted.

Once I got past these, works fine and I get a notification on my smart things app when it detects water.
