If you\u2019ve ever relied on a standard water leak detector, you might have realized they all share a common, frustrating flaw: they only measure from a single, specific point. If a pipe bursts or a manifold leaks and the water happens to pool just 10 centimeters away from your sensor, the device won’t notice a thing until the damage is already done.<\/p>\n\n\n\n

Shelly is aiming to solve this exact problem with the newly designed Shelly Flood Gen 4<\/a>. Instead of relying on a tiny localized sensor, this new iteration utilizes a specialized sensor cable designed to detect leaks across a much larger surface area.<\/p>\n\n\n\n
