Review: Brilliant Water Sensor! - The SwitchBot WiFi Water Sensor is an absolute game-changer for home protection! Setting it up was a breeze — just connect it to your 2.4Ghz Wi-Fi, and you're good to go. No extra hub needed, which is a huge plus. The app is intuitive and user-friendly, delivering real-time alerts straight to your phone whenever it detects leaks, drips, or flooding. It’s fantastic for peace of mind, especially when you’re not home. The build quality is impressive, with an IP67 waterproof rating, making it perfect for kitchens, bathrooms, basements — pretty much anywhere. The sensitivity of this thing is unreal. It has four sensor probes and can detect even a tiny 0.5mm water level! And if something goes wrong, the 100dB alarm ensures you won’t miss it, even from afar. The app integration is smooth, and I love how it works with Alexa, Google, Siri, IFTTT, and SmartThings. It even pairs with the SwitchBot ecosystem, letting you control other devices if a leak occurs. All in all, this little device packs a serious punch. It's reliable, well-built, easy to set up, and the app makes everything super convenient. Highly recommend!
Review: Easy to set up - Purchased after a water leak on a copper pipe behind washing machine. Only discovered it when the kitchen floor was covered with water. Bought a set of 3 switchbot sensors, easy to set up, work well when tested with water across the contacts and the app appears to give a timely alert. Good to have but hope not to hear the alarm anytime soon.

## Features

- Real-time Notifications (No Hub Needed): After connecting to Wi-Fi, you will be able to receive real-time email and app notifications remotely when dripping, leaking, or flooding is detected, without the need to purchase an additional hub. Share devices with family, and they can also check home status at any time. (2.4Ghz Wi-fi & BLE)
- High Sensitivity Drip Alarms: This device is equipped with four sensor probes at the top and bottom, which can detect a low water level of just 0.5mm. If water pipes drip, and your floor is submerged, or gets wet, it will sound an alarm. Water Leak Detector is compact and convenient in size, suitable for placement in laundry rooms, water heaters, dishwashers, sinks, and other places.
- Includes Loud Alarm Sounds: To help you stay alert, we've included 100dB high pitched alarms, which means even if there is a leak in basements or places a little further away, you'll know in a timely manner. Once discovered, you can manually set it back to mute without worrying about noise issues.
- IP67 Waterproof, Up to 24 Months Battery Life: Water Leak Detector is designed with a fully sealed waterproof shell and can easily handle high humidity working environments. It comes with 2 x AAA batteries and has a battery lifespan of up to 24 months. When battery is low, our app will also send notifications to remind you to replace them in a timely manner.
- Part of SwitchBot Ecosystem, Voice Command Compatible: Use with SwitchBot Plug Mini or Indoor Cam, and remotely turn off electrical equipment or check the condition of your house in case of leakage. It can also support third-party services such as Alexa/Google/Siri/IFTTT/SmartThings.
