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 ;-) Review: Smart, Well Designed & Home Assistant Ready – Spot on from SwitchBot - I couldn’t be more impressed with this leak detector. The cabled version is fantastic value, effectively giving you three sensors in one. The engineering is smartly thought out — the top-mounted sensor sits in a dished recess, which cleverly allows drips to collect and trigger the alarm more quickly. It also has a built-in alarm for immediate local alerts, which is a lifesaver if you’re nearby. Connectivity is excellent: it works flawlessly with the SwitchBot app and cloud services, but it also integrates perfectly with Home Assistant via ESP32. In fact, setup with HA was even faster and more seamless than with the official app. Someone mentioned it didn’t work, personally didn’t have a single issue getting it to work. It was picked up by ESPHome instantly. I was torn between this and the Eufy option, but honestly this has far more bells and whistles, and the Home Assistant functionality is spot on — exactly what I needed for my setup. The build quality, design, and reliability are outstanding. I had the unfortunate experience of a copper pipe bursting (after rubbing against a rusty RSJ), which flooded two rooms in my office. I only wish I’d bought this device sooner — it would have saved me a lot of hassle. If you’re looking for a well-designed, highly reliable, and affordable leak detector, this is absolutely the one to get. ⭐ ⭐ ⭐ ⭐ ⭐ ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DMW6G2LY | | Battery Description | Alkaline | | Battery description | Alkaline | | Best Sellers Rank | 5,904 in DIY & Tools ( See Top 100 in DIY & Tools ) 1 in Water Detectors | | Brand | SwitchBot | | Colour | White | | Compatible Devices | Smartphone, Tablet | | Compatible devices | Smartphone, Tablet | | Control Method | Touch | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 230 Reviews | | Included Components | AAA Battery, User Manual, Warranty Card, Water Leak Detector with Sensor Cable*3 | | Item Dimensions L x W x H | 5.9L x 2.5W x 5.9H centimetres | | Item Type Name | Water Leak Detector | | Item Weight | 68 Grams | | Manufacturer | Wonderlabs | | Maximum Range | 1700 Feet | | Model Number | W4402000 | | Mounting Type | Tabletop Mount | | Number of Batteries | 1 A batteries required.
