Our take
These Moen sensors connect directly over WiFi and watch for leaks, high humidity, and freeze risk, sending app alerts and sounding an onboard alarm. They're best in a Moen ecosystem where they can trigger the Flo automatic shutoff valve, but the recurring FloProtect subscription for full features and CR123A batteries are downsides.
What we like
- Detects water, humidity, and freezing temperatures, not just leaks
- Connects directly to WiFi without a separate hub
- Integrates with the Moen Flo shutoff valve for automatic water cutoff
- Clean, reliable Moen Smart Water app and Alexa/Google support
What to keep in mind
- Best features and history gated behind a FloProtect subscription
- Uses CR123A lithium batteries lasting only about 2 years
- More expensive than basic sensors and most useful only within Moen's ecosystem
