Key features

The SwitchBot WiFi Water Sensor 3‑pack is a compact smart leak detector that connects directly to 2.4 GHz Wi‑Fi without a hub, offering real‑time app and email alerts when water is detected. Suitable for kitchens, bathrooms and basements, it uses four sensing probes to spot very low water levels, helping you act before damage spreads.

Why it’s worth it

This kit combines sensitive detection and loud alerts without the need for extra hardware. The built‑in 100 dB alarm is loud enough for many basements and utility rooms, and app notifications reach you wherever you are. It integrates with the SwitchBot ecosystem and supports Alexa, Google Assistant, Siri Shortcuts, IFTTT and SmartThings, so you can trigger actions such as switching off a plug or checking a camera feed when a leak is reported. Bear in mind that it requires a 2.4 GHz Wi‑Fi network only, so dual‑band setups may need configuration.

Best use cases

Place one near dishwashers, washing machines or beneath sinks and another close to water heaters or under exposed pipework. It’s small enough to sit discreetly but sensitive enough to detect just 0.5 mm of water at the probes, which makes it useful for slow drips as well as sudden floods. It makes sense if you want unobtrusive, always‑on protection with straightforward alerts and ecosystem automation.
