Buying Guide

Choose the right sensor type

Decide between spot probes, flat leak sensors, or wired probe sets depending on where leaks are likely (under sinks, near water heaters, or along floor lines)

Check connectivity options

Wi‑Fi, LoRa/long‑range hubs, and simple wireless RF affect range and integration with smart‑home systems—pick the protocol that fits your home network and automation needs

Consider kit vs. single sensors

Starter kits that include a hub plus one or more sensors simplify setup and expandability compared with standalone battery detectors

Evaluate alarm & notification methods

Look for devices that combine local audible alarms with remote notifications via app or hub so you’re alerted both on site and off site

Look at power and maintenance

Battery‑operated units are convenient for placement but check expected battery life and ease of replacement; some hubs require mains power
