Smart Water Alarm

Alerts you reliably in the event of a water leakage

Reliable: The Smart Home Water Alarm alerts you at an early stage and prevents damage

Make your home more secure. The smart Water Alarm informs you in the event of a water leakage – visually, acoustically and via app - and thus reliably prevents significant material damage.

Reliable alarm

The smart Water Alarm alerts you at home in the event of a water leakage acoustically by means of beeping and visually by means of the blue flashing of your Philips Hue lights.

Notification via app

The Smart Home Water Alarm also informs you when you are out via push notification and live image. See what is happening at home and make an emergency call directly via the app.

Immediate damage limitation

In emergencies, use an automation to deactivate devices connected to plugs in a flash. In this way, you can immediately protect your house from major water damage.

Alerts you at home and when you are out – allowing you to respond quickly

Wherever you are, the smart Water Alarm notifies you as soon as it notices a water leakage. At home, you are alerted by flashing lights. When you are out, you receive a push notification in the app including live images of your integrated Bosch Smart Home cameras. You thus quickly gain an overview of the situation at home. Thanks to the emergency call speed dial, you can respond particularly quickly in a hazardous situation.

Damage limitation thanks to intelligent networking

In the event of a water leakage, the Water Alarm deactivates devices connected via plugs. You thus avoid major hazards due to water damage on electrical devices.

Stays where it should be

The slip-proof silicone coating on the underside of the Smart Home Water Alarm ensures that your alarm stays put. Even so, should the Water Alarm be moved accidentally, such as when you are cleaning or by your pets, you will be informed immediately via the app.

Inconspicuous and flat – but really impressive-looking

The Water Alarm not only protects your home, but also looks good. Thanks to its elegant and compact design, the wireless Smart Home Water Alarm can be placed completely inconspicuously under most washing machines or in other places. Installation, operation and battery replacement are performed quickly and intuitively.

Stays connected remotely as well

Even if your washing machine is in the basement, you need not be concerned about the wireless signal strength of your Water Alarm. Thanks to the range extension of the Plug Compact, this can also be ensured in isolated rooms.
