MOXIV’s smart water detectors solve a basic but critical problem: they tell you about a leak the moment it happens, even when you’re not home. The key is the direct Wi-Fi connection. Since there’s no separate hub to buy or configure, you can have a sensor online and sending alerts in minutes.

Each puck-shaped detector uses two included AAA batteries and connects to your 2.4GHz network. When its sensors get wet, a sharp 120dB local alarm sounds. Simultaneously, you get a push notification and email. The 500-foot wireless range means you can reliably place these in far-flung basement corners or under a sink far from your router. It’s a set-and-forget kind of security.

The three-pack is the practical starting point for covering a home’s main risk areas: behind the washing machine, under the kitchen sink, and by the water heater. Just remember to test the app connection during setup and replace the batteries annually. For a straightforward early warning system, this setup removes a significant amount of silent worry.
