Key Features & Innovations

Detects Burst Pipes Automatically Shuts Off the Water Supply and Alerts You

Grohe Sense Guard detects a pipe break and automatically shuts off the water supply to prevent your home from being flooded. It alerts you with a pulsating red light and a beeping sound. Even if the system loses Wireless LAN connectivity, the AquaIQ algorithm ensures it works independently

Shuts-Off-the Water Supply Manually or Automatically-If a Pipe Bursts

Think of the worst thing that can happen when you’re on holiday: a pipe bursts, the cellar gets flooded, mold creeps up the walls, the furniture is ruined and… stop right there! With Grohe Sense Guard, the moment a pipe breaks AquaBlock closes the valve, shuts off the water and saves the day – and the holiday!

Detects Even Tiny Leakages and Alerts You

Leaking pipes – along with leaking taps, showers and toilets – cause 28% of all water damage! The smallest leaks can go unnoticed for years, completely saturating walls and floors and causing extensive damage. Grohe Sense Guard detects all kinds of micro leaks and alerts you so you can react.

Ensures All Alerts and Actions Match Your Household Consumption

The self-learning algorithm ensures that all alerts and actions are perfectly adapted to match your household consumption. It discovers anomalies early and informs you of all unusual water consumption.

Detects If Incoming Water Could Freeze and Instantly Alerts You

A frozen pipe can occur during extended periods of frost, especially in areas that are not often checked such as the cellar or weekend home. GROHE Sense Guard senses the water temperature as it enters your house and gives you a warning if there is a risk from frozen water.

Works with Nest to Provide Even Higher Water Security

For an even higher level of water security Grohe Sense Guard works with Nest. When you leave home, GROHE Sense Guard can shut off the water automatically – either immediately or with a time delay (e.g. if you leave washing machine on). And when you return home, the water supply is automatically turned back on.

Mobile Device App to Manage Connected Grohe Products

A user-friendly app that gives you complete control over all your connected Grohe products. Using intelligent cloud-based technology, the GROHE ONDUS app for iOS and Android guarantees maximum water enjoyment and safety.
