GROHE Sense has two gold plated pins on the bottom. When water floods and connects the two pins, a short-circuit generates an alarm that is immediately sent out to the app.

An alarm is sent to you and your emergency contacts via a notification, SMS, and email - depending on your notifications settings. The device will also start blinking red and beeping. If you are using GROHE Sense the accoustic and optical signal will stop after 1 hour and start blinking and beeping again after 23 hours (each day until the batteries are empty). The alarm of Sense+ does not stop in between. To stop the device alarm dry the metal contact pins on the bottom of the device with a lint-free rag.

Temperature and humidity are constantly measured, the device senses every 60 minutes. Every day the humidity and temperature information is stored in the GROHE ONDUS cloud.

If you want to have more control, go for GROHE Sense+. With GROHE Sense+ you additionally have the possibility to get the current temperature & humidity levels with clicking the "Trigger Update" Button in the app.

Both products measure temperature and humidity are constantly. GROHE Sense sends the humidity and temperature information once a day to the cloud. With GROHE Sense+ you additionally have the possibility to get the current temperature & humidity levels with clicking the "Trigger Update" Button in the app.

GROHE Sense measures relative air humidity. Relative humidity is dependant on the temperature. A 100% humidity level would mean the air is completely saturated with water at that temperature.

Install GROHE Sense inside your home in any location where there is flood risk or where you want to have humidity control.

• Install a GROHE Sense in your cellar, as the chances of having a water damage, are high
• Install below sinks or wash basins, as often people see leaks here way too late
• Nearby your washing machine, to be sure nothing happens
• On attics where you have windows that you often leave open for ventilation, to detect fast enough that rain does not flood inside.

First download the app from the Apple Appstore or the Google Play store, register yourself and setup your house and rooms if you did not do already. Add GROHE Sense to the room of your choice by clicking the + symbol or by adding it via the catalogue. Give a name and define the room, place the 3 AAA batteries (included in the box) and connect the WLAN by selecting the GROHE Sense SSID and typing in the password you find on the backside of the product. If you already installed the product and it is hard to see the password, please use your mobile device to take a picture with a flashlight.

Then place GROHE Sense on a flat surface (non-metallic/non-conductive) with the pins touching the surface.

Try the extension set 22506LN0 that has an extension cable length of 1,2 m. Mount the base plate of the extension set with the two screws on the wall. Place the remote sensor on a flat surface (non-metallic/not-conductive) with the two pins touching the surface.

You can also install GROHE Sense+ if you want both the extension and a mains powered product.

Several solutions might be possible:

• You can always install an additional repeater that strengthens the WLAN signal closer to the product.
• If you have a UTP connection available, install an access point or repeater (you can typically choose between these two operating modes) directly on the UTP connection.
• The last option could be to use power cable products. Here you install one power cable connector near the router and one near the product. Choose for a power cable product that has WLAN functionality, or you need an additional repeater/access point.

GROHE Sense is a water sensor of ø 84 mm and a height of 35 mm.

The extension set consists of a wall plate of ø 84 mm, is 38mm high including the sensor and a remote sensor of 10 mm height and 50 mm diameter. It has an extension cable of 1,2 m.

GROHE Sense+ has the same dimensions as the GROHE Sense and uses the same extension set and has an additional power cable of 0,6 m.

GROHE Sense is protected against spraying and splashing water (IPX3). In the case of a flooding, please dry it immediately. If you have to clean the device, please use a lint-free rag. DO not use any detergents.

Either you replace the 3 AAA batteries, or in the case you need permanent information, please purchase GROHE Sense+ which is connected to the mains electricity supply and therefore needs no batteries.
