Flood Sensor is a universal, Z-Wave compatible, flood and temperature sensor. Device can be battery or VDC powered. Flood alarm is sent to the Z-Wave network devices or additionally to any alarm system controller, through opening a NC contact.

Fibaro Flood Sensor is a smart device designed to detect and alert you to water leaks and potential floods. It is typically placed near areas prone to water damage such as near washing machines, sinks, toilets, and sump pumps. The sensor can detect even small amounts of water and send an alert to your smartphone or tablet, allowing you to take action before the damage becomes severe. The device is equipped with multiple sensors that monitor temperature, humidity, and water presence, and it can be integrated with a smart home system such as HomeKit, Google Home, or Amazon Alexa. This allows you to set up automations and routines to respond to a flood or leak, such as automatically turning off the water supply to prevent further damage. In addition to its practical use, the Fibaro Flood Sensor is also designed to be aesthetically pleasing and blend in with your home decor. It's compact and battery-powered, making it easy to install and maintain.

Perfectly Designed

The FIBARO Flood Sensor is a perfect dance between art and design - beautiful and harmonious in every little detail. Just like in other FIBARO devices, the perfect form is equipped with the most advanced technology.


  • Compatible with any Z-Wave controller, Z-wave or Z-Wave+ Controller (firmware 3.2 or higher)
  • Supports protected mode (Z-Wave network security mode) with AES-128 encryption (firmware 3.2 or higher).
  • May be connected to any alarm system (potential free output terminal)
  • Extremely easy installation – simply put on a surface prone to flooding
  • May be installed anywhere – flood sensor’s contacts extended with a wire
  • Battery or VDC powered. When connected to an external, 12/24V DC power source, the battery serves as an emergency power source
  • Theft protection – tilt is reported to the Z-Wave network or alarm system’s main controller
  • Two operating modes – flood/temperature sensor or just a temperature sensor.
  • Alarm is signalled by sound, visual indicator (LED diode) and Z-Wave

Frequently Asked Questions

I have replaced the battery because FIBARO interface signaled its low state but I still see red, blinking battery icon. How to reset the battery level?

The battery level report is sent at the same time as sensor’s wake up. You can wait a specified period of time or perform manual wake up by triple clicking the TMP button.

The widget is in an alarm state (small blue drops) after the inclusion. Why?

The alarm state of the sensor is caused by tamper intrusion. There are two sources of tamper – one from opening the case (triggering the Button – Tamper switch) and one movement/position tamper. You have to close the sensor cover, put the device away and wait for reconfiguration or wake up event (it can take up to 1.5 hours depending on configuration).

 I have recently installed an electrovalve on my main water supply and wanted to associate FIBARO Flood Sensor with it but “Association” field in Advanced configuration is empty. What is the problem?

Please reconfigure the device. It is not properly included.

What features, comparing to battery mode, Flood Sensor offers in DC powering mode?

In DC powering mode the sensor does not require wake up, configuration and associations parameters are sent when necessary. In addition the sensor serves as a Z-Wave signal repeater.

Is it possible to easily check if the sensor has a good Z-Wave range and can communicate with the FIBARO System?

Yes, FIBARO Flood Sensor has a built-in Z-Wave controller’s range tester.

Can I turn off acoustic and visual signals?

Yes, you can disable them in parameter 2. Available settings:
0 – acoustic and visual alarms inactive
1 – acoustic alarm inactive, visual alarm active
2 – acoustic alarm active, visual alarm inactive
3 – acoustic and visual alarms active
