Hyjoy 4-Pack Smart Water Leak Sensors — App Alerts for Kitchen & Bathroom, Coin-Size WiFi Leak Detectors

Compact, button-style water leak detectors that are slightly larger than a coin and comfortable to handle. Each unit is designed to sit unobtrusively in corners or next to appliances and fixtures — ideal for toilets, washing machines, sinks, water heaters and basements. Receive instant notifications on your smartphone (iOS/Android) through the companion app so you can act quickly when a leak is detected. Requires a 2.4GHz WiFi connection (not compatible with 5GHz); the system provides whole-house coverage up to 100 feet and supports connecting up to 128 leak sensors to monitor multiple rooms and devices. For reliable operation, place each detector on a clean, dry surface to minimize false alarms. These sensors integrate with the Hyjoy smart product family to create coordinated automations, delivering real-time alerts to protect your property while helping reduce repair-related expenses.You may also like Hyjoy WD61 5-Pack Water Leak Detectors — 120dB Alarm, Drip & Flood Probes, 4 Volume Levels, 2 AAA, W13 WiFi Compatible (TUYA).
