Review: Worth it! Saved us a fortune - These things have now saved us a fortune. It detected a water leak near our main water stop valve, not once but twice! Both items it alerted us to a problem before it became a serious issue and we could get a plumber in to fix the issue before destroying property. I did however have to 3D print some fancy 'funnel' sort of holders, so it has the possibility of catching more water drops, should we get any. It does however have detectors on both sides of the remote probe, and then both sides of the ain box itself....so it's fairly well covered. Only improvement I'd love to see, is the alert to tell you which if the sensors is triggered on the device, but it looks like all the sensors go to a single point...probably a cost and battery saving measure, so I do understand
Review: SwitchBot Sensors Keep Your Home Leak‑Free (with zero hub) - I recently installed a three pack of SwitchBot WiFi Water Sensors, and they’ve become an indispensable part of my smart home setup. Integrated directly into Home Assistant without any hub, each sensor keeps an eye on my boiler tank and the bathroom sink. Whenever there’s a sudden spike in water level, whether it’s a hidden leak or a bath that’s about to overflow the sensors trigger instant alerts on my phone and dashboard, giving me peace of mind before any damage can occur. What makes these sensors truly standout is their battery life and coverage. A single charge lasts for months under normal use, and the WiFi range comfortably covers my entire house without signal loss. Coupled with an incredibly reasonable price point, the SwitchBot Water Sensors provide high‑value protection that feels like a small investment in major safety and convenience. I highly recommend them to anyone looking to add reliable leak detection to their smart home ecosystem. Switchbot your sensors are always 5-star material ;-)

## 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.
- Water Level Detection: Equipped with a 1-meter extended probe, you'll be able to detect changes in water levels of places like swimming pools, bathtubs, and fish tanks. It can also be placed in narrower areas, such as bottom of refrigerators or back of washing machines. And is suitable for homes, warehouses, basements, sinks, water heaters, pipelines, and more.
- 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
