A water leak can be one of the most expensive accidents to happen in your home. (Ask me sometime about ABT’s installation of a faulty fridge valve that caused over $20K in damage in our kitchen.)
I recommend you buy several Govee Water Leak Detectors and place them anywhere a leak might occur. The loud alarm could save you a lot of money, as it’s easy for a leak to escape detection until after it has done significant damage.
If you know me as a home automation expert, it might be surprising that these are non-automated, standalone alarms. But this is a perfect example of when isolated, inexpensive, and reliable sensors are the best choice. These are “set it and forget it” simple, and you won’t miss an alert due to network interference or a technology mismatch. Additionally, you can buy five of these for half the price of one automated sensor. (Buy from Amazon.)
That said, if you’re hellbent on unnecessary complications, you can apparently get a hub and an app from Govee that will work with these. Instead, I suggest you just convince yourself that you’re deploying a fleet of autonomous robot guardians, then get on with your life and hope that they only problem they ever detect is a low battery.
