QUICK SUMMARY
Shelly has launched the Flood S Gen4, a compact smart water leak sensor designed to detect even small amounts of water.

Shelly has announced the launch of its latest smart water leak sensor, designed to detect even small amounts of water before they have a chance to cause costly damage. The new Shelly Flood S Gen4 joins the brand's growing Gen4 lineup and comes with Matter support for wider smart home compatibility.
Instead of the smaller pin-style contacts found on some leak sensors, the Flood S Gen4 has three large stainless-steel sensors across its base, creating a much wider contact area. This is designed to pick up small amounts of water quickly, reducing the time between a leak starting and an alert being sent.
The Shelly Flood S Gen4 is available now, priced at £18.90 in the UK and $27.99 in the US via Shelly's website and authorised distribution partners.
Much like IKEA's popular Klippbok water leakage sensor, Shelly has kept its new model small and low-profile. That means it can be slipped underneath appliances, sinks and toilets where leaks can easily develop without being noticed.
If water is detected, the Flood S Gen4 sends an alert directly to your smartphone whilst also sounding its built-in alarm. This means you'll have a warning whether you're at home or away, rather than relying entirely on a phone notification that could easily be missed.
There are also two operating modes, with Flood Detection designed for indoor leaks and Rain Detection offering another option for different environments. You can choose between three alarm profiles – Intense, Normal and Economic – depending on whether you want to prioritise faster detection or longer battery life.
The Flood S Gen4 is battery-powered, with Shelly claiming up to two years of use from the included CR123A battery. Alongside support for Matter, Wi-Fi and Zigbee, it's compatible with major smart home platforms including Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant.
