Grohe 22601LN0 Smart Water Sensor User Guide

Grohe 22601LN0 Smart Water Sensor

INTRODUCTION

Congratulations on your new GROHE Sense water security system! Now your house is equipped with a reliable solution for every day, where you no longer have to worry about water damage.

The system consists of two smart devices, GROHE Sense and GROHE Sense Guard, and a smartphone app GROHE Sense. Each of the devices can be used individually, if more devices are installed on the property, they all work together to provide a higher level of water security.

GROHE SENSE GUARD – THE SMART WATER CONTROLLER

GROHE Sense Guard water controller is installed on the main water pipe. It literally sees all the water passing by, checks for unusual water use, and tracks water consumption.

When it detects a leak, it can shut off the water supply automatically to reduce consequential damage. It detects even very small leaks so that you can take action before the leak becomes bigger.

GROHE SENSE – THE SMART WATER SENSOR

GROHE Sense water sensor detects the presence of water, tracks temperature and humidity, and alerts you automatically when an issue is detected. It can also trigger the GROHE Sense Guard to automatically shut the water off.

GROHE SENSE APP – PERSONAL WATER MANAGEMENT APP

GROHE Sense app is your control tool for all GROHE Sense water security devices. The app shows the latest status and measurements of the devices, delivers alarms and warnings, lets you change the settings of the devices, and manages your account preferences.

TROUBLESHOOTING

WHAT TO DO IF THE DEVICES DON’T CONNECT

STEP 1: CHECK WHETHER YOU HAVE SUFFICIENT WIRELESS NETWORK COVERAGE

There may be a problem with your wireless network coverage. See below for some potential causes and solutions. An app for testing your wireless network may be a useful way to identify any problems (e.g. Android: Wi-Fi analyzer, iOS: Wi-Fi SweetSpots).

DISTANCE

POTENTIAL PROBLEM: The device is too far from the router.

TEST: Check the performance of your wireless network as you move further away from your router.

SOLUTION: To solve this problem, you can either install a repeater or a new router offering enhanced performance.

OBSTRUCTIONS

POTENTIAL PROBLEM:  Obstructions such as thick walls or closed doors weaken the wireless network signal.

TEST: Test the performance of your wireless network on one side of the wall or with closed doors and compare it with the performance on the other side of the wall or with open doors.

SOLUTION: You can use powerline adapters, which transmit the wireless network’s signal along the building’s existing electrical wiring.

OVERLAPPING WI-FI NETWORKS

POTENTIAL PROBLEM: Multiple wireless networks are overlapping in one area. Every router automatically selects and uses a channel. The channels are numbered 1 to 11. In densely populated areas, networks that are using the same channel may overlap.

TEST:   The Wi-Fi testing app will show you which channels are used most heavily.

SOLUTION: Manually change the channel that your router uses. Select a channel that is not too heavily used. To make this change, read your router’s manual.

TOO MANY DEVICES

POTENTIAL PROBLEM: There are too many devices using the same wireless network. This can slow down the wireless network’s performance – particularly if users are constantly downloading or streaming videos.

TEST: The Wi-Fi testing app shows you how fast your wireless network is.

SOLUTION: Install a router with a higher capacity.

STEP 2: IF YOUR WIRELESS NETWORK COVERAGE IS  SUFFICIENT, THERE MAY BE A PROBLEM WITH YOUR ROUTER SETTINGS

ARE YOU USING A WIRELESS NETWORK WITH A FREQUENCY OF 2.4 GHZ?
In order to be able to integrate the Sense device into your wireless network, the network needs to use a frequency of 2.4 GHz. The device will not work with a frequency of 5.0 GHz. You can view and change the frequency in your router’s settings.

IS YOUR PRIVATE WIRELESS NETWORK SECURED WITH WPA/WPA2?
GROHE Sense does not work with open wireless networks. It requires a wireless network that is secured with WPA or WPA2. Your private wireless network therefore needs to be protected by a password that has at least eight characters.

IS MAC FILTERING ACTIVATED?

• MAC filtering is a method for protecting wireless networks. If it is activated, the wireless network router will only give approval to known/registered devices.
• MAC filtering is not normally activated by default.
• It usually needs to be set up manually. If you have MAC-activated MAC filtering, please deactivate it or add the
• MAC address of the GROHE Sense to your router’s list.
• To find out the MAC address of your GROHE Sense, download the app for testing your wireless network and initiate the device’s integration mode (blue flashing LED) by inserting the batteries. Then connect the device to your smartphone. The app will display the MAC address of your device.

OTHER POSSIBLE REASONS:

• Are the ports 443 (HTTPS) and 80 (HTTP) open?
• Is DHCP activated on your router?
• Does the router support IPv4?

For more information and solutions to these reasons, check Wi-Fi instructions at help.grohe-sense.com or in the GROHE Sense app.

If all fails, perform the following test to identify if the connectivity error originates from the GROHE product or from the router: activate a Wi-Fi hotspot on a second smartphone. Try to connect the GROHE product to this Wi-Fi hotspot, instead of your home Wi-Fi network. If connection is established successfully, the reason for your connectivity issue originates from your router.

WARNINGS AND REACTIONS

GROHE SENSE GUARD WARNINGS AND HOW TO REACT

A complete list of all notifications triggered by GROHE Sense Guard is included here. You can always get more specific information and support directly in the app by tapping the “Help” button in the notification. After you have taken note of the message, you can mark it as read.

NOTIFICATIONS RELATED TO WATER LEAK AND WATER SHUT-OFF

• GROHE Sense Guard warns you only when it detects a highly unusual water use pattern that indicates a possible water leak in your system. Each alarm should be taken seriously.
• You might experience false alarms after the installation of the device. In this case, it is necessary to identify the cause for these alarms and make an appropriate change in the GROHE Sense Guard preferences or settings of other water-consuming devices. If you can’t identify or solve the cause, contact GROHE customer support.
• When you receive a warning indicating that water is leaking on your property, try to identify the leak and its source. Depending on the cause and severity, take first prevention measures to minimize the damage. If needed, call an installer, and contact your insurance company.
• If the GROHE Sense Guard automatically shuts off the water, make sure that you have mitigated the reason for the alarm before turning the water back on. You can turn the water on by pressing the button on the device or in the app.

EXTREMELY HIGH FLOW RATE

EXPLANATION

Your water flow rate exceeded 50l/min, and as a security measure your water has been shut off. Very high water flow can be an indication of a pipe break.

Other possible causes:

•  A high flow rate can occur when several tapping points are opened at the same time
• In rare cases high flow rate can be caused by a water pump filling up the water system of the house

RECOMMENDATION WHAT TO DO

Identify the root cause of why the water was shut off, and take appropriate action:

• Situation 1: You have used several water tapping points at the same time when the water was turned off.
• Solution: Re-open the water supply in the app or on the device.
• Situation 2: Check your household for water leaks – look also for signs of structural damage (e.g. cracks, holes).
• Solution: Depending on the cause and severity, take first prevention measures to minimize the damage. If needed, call an installer, and contact your insurance company.

MAXIMUM VOLUME REACHED

EXPLANATION

• A large volume of water has been used at once without any stop, and as a security measure your water has been shut off. This volume was higher than the defined maximum limit in your device preferences.
• GROHE Sense Guard tracks water consumption per water event – it starts counting from zero every time the water flow stops.

Typical reasons for exceeding the volume limitation are:

• Filling of large bathtubs
• Long non-stop showers
• Watering of the garden
• The faucet was left open unintentionally
• Multiple overlapping water usages (e.g. filling the tub and showering at the same time)
• Leak in the piping system

RECOMMENDATION WHAT TO DO
Identify the root cause of why the water was shut off, and take appropriate action:

• Situation 1: You know that you have used a large volume of water when the GROHE Sense Guard reacted and there is no water damage.
• Solution: Re-open the water supply in the app or on the device. To prevent a shut-off next time, consider changing the preferences of your GROHE Sense Guard:
  • Increase the volume limitation (default value is 300 liters)
  • Activate the garden sprinkler mode when using a large volume of water
• Situation 2: You think that you did not use a large volume of water.
• Solution: Check your house for possible causes of the shut-off:
  • An open faucet
  • Water leaks, if you don’t see water, look for water stains or other signs

Depending on the cause and severity, take first prevention measures to minimize the damage. If needed, call an installer, and contact your insurance company. When the risk has been mitigated, re-open the water supply.

UNUSUALLY HIGH WATER CONSUMPTION

EXPLANATION

Abnormal consumption patterns have been detected. Depending on your device preferences, your water may have been automatically shut off.

Typical reasons for unusually high water consumption are:

• Filling of large bathtubs
• Long non-stop showers
• Watering of the garden
• The faucet was left open unintentionally
• Multiple overlapping water usages (e.g. filling the tub and showering at the same time)
• Leak in the piping system

RECOMMENDATION WHAT TO DO

Identify the root cause of why the water was shut off, and take appropriate action:

• Situation 1: You know that you have used large amounts of water when the GROHE Sense Guard reacted and there is no water damage.
• Solution: Re-open the water supply in the app or on the device; if your water supply was shut off. You can also consider deactivating the automatic shut-off function in the device preferences.
• Situation 2: You think that you did not use large amounts of water.
• Solution: Check your house for possible causes:
  • Running water, such as a water faucet unintentionally left open, or a leaking toilet
  • Water leaks, If you don’t see water, look for water stains or other signs

Depending on the cause and severity, take first prevention measures to minimize the damage. If needed, shut off your water supply, call an installer, and contact your insurance company. When the risk has been mitigated, re-open the water supply.
If you get this message repeatedly during normal usage of water, please contact customer service.

WATER DETECTED BY GROHE SENSE

EXPLANATION

One of the GROHE Sense water sensors installed in your house detected water. Depending on your device preferences, your water may have been automatically shut off. Please note that GROHE Sense is sensitive, and it is enough for a small amount of water under the device to trigger a flooding alarm.

RECOMMENDATION WHAT TO DO

Locate the GROHE Sense and check why it has detected water. In case of flooding, GROHE Sense blinks red and sends out an acoustic signal.

Depending on the cause and severity, take first prevention measures to minimize the damage. If needed, shut off your water supply, call an installer, and contact your insurance company. When the risk has been mitigated, re-open the water supply.

PRESSURE DROPS DETECTED

EXPLANATION

GROHE Sense Guard has detected pressure drops in your water system. Depending on your device preferences, your water may have been automatically shut off.

GROHE Sense Guard conducts several pressure tests:

• A thorough pressure test every night.
• Multiple short pressure tests during the day.

During these tests, very small pressure changes can be detected, which indicate that your water system is not tightly closed and that a small quantity of water is leaking from the system.

Common reasons for a detected pressure drop are:

• Dripping faucets, valves, or leaking toilets
• Appliances consuming small amounts of water
• Temperature changes in the pipe system, in cases such as
• Hot water pipes are not properly isolated and heat up Also the cold water pipes
• Missing backflow preventer on the hot water pipe leads to pressure changes also in the cold water pipe
• Leaking pipe

RECOMMENDATION WHAT TO DO

Check all water exit points in your house thoroughly. Leaks detected by a pressure test can be extremely small and difficult to find. Therefore, it often takes time to detect the cause and solve the problem.
Here are some examples of how you can find possible causes:

• Check all faucets and valves in your household for drips. If you have doubts, place a dry tissue below the faucet/valve and check later if the tissue becomes wet. Also, check remote faucets (e.g. in your garden) and valves below the sinks.
• Check for leaking toilets. Check if you can hear a hissing sound or see dripping in the toilet. You can also place some drops of food coloring in the lavatory cistern. Wait a few minutes. If you see coloring in the bowl, you most probably have a defective float valve.

If you cannot find a dripping faucet, valve, or a leaking toilet, carefully monitor your house for water stains. If you find a sign of a water leak, contact your installer and depending on the severity consider turning off your water supply. If you cannot find a leak, we recommend that you contact GROHE customer support.

WATER SYSTEM CHECK NOT POSSIBLE

EXPLANATION

GROHE Sense Guard conducts a pressure test every night at 3:00. If this test cannot be conducted multiple times, you will receive this notification.

GROHE SENSE IN DETAIL

HARDWARE

These are the functions of GROHE Sense:

• Detects water on the floor (e.g. water leaks, flooding)
• Senses humidity
• Measures temperature and detects frost risk

To provide these functions, the device is equipped with:

• Two water-detecting metal pins on the underside of the sensor
• Temperature sensor
• Humidity sensor

For correct functioning, the device needs:

• Batteries (3x AAA)
• Stable Wi-Fi connection, established with the use of a smartphone and GROHE Sense app
• Placement on a flat area of non-conducting material, ideally at the lowest point in the room.

It is recommended to place GROHE Sense at a location with an increased risk of water leak or high humidity:

• At the water boiler and the central heating system
• Under the incoming water pipe upstream of the GROHE Sense Guard
• Other specific locations in the cellar, the laundry room, the bathroom or the kitchen

To provide long battery life, the functions are defined in the following way:

• Flooding detection is always active
• Temperature and humidity are measured once per hour
• The readings are updated in the app once per day as long as the values stay within the set thresholds
• Trigger for an alarm of crossing the set thresholds is always active

CONTROL VIA SMARTPHONE

GROHE Sense is a smart home device that is controlled with the use of GROHE Sense app.

A complete list of all notifications triggered by GROHE Sense is included here. You can always get more specific information and support directly in the app by tapping on the “Help” button in the notification. After you have taken note of the message, you can mark it as read.

FLOODING NOTIFICATION

EXPLANATION

Your GROHE Sense has detected water.

Please note that GROHE Sense is sensitive, and it is enough for a small amount of water under the device to trigger a flooding alarm.

RECOMMENDATION WHAT TO DO

• Locate the GROHE Sense and check why it has detected water. In case of flooding, GROHE Sense blinks red and sends out an acoustic signal.
• Depending on the cause and severity, take first prevention measures to minimize
• the damage. If needed, shut off your water supply, call an installer, and contact your insurance company. When the risk has been mitigated, re-open the water supply.

HUMIDITY AND TEMPERATURE NOTIFICATIONS

HIGH / LOW HUMIDITY

EXPLANATION

Room humidity is measured on a continual basis, once per hour. As long as the values stay within the set thresholds, the readings are updated in the GROHE Sense app once per day. If humidity stays above or below the set thresholds for more than 3 hours, you will be automatically notified by the app.

Relative humidity is normally expressed as a percentage and indicates how much water the air contains in relation to its maximum absorption. A higher percentage means that the air is more humid. At 100 % the air is completely saturated with water and cannot absorb any additional water.

The maximum capacity of water absorption depends on the temperature and pressure. Higher temperatures lead to higher humidity.

The ideal relative humidity in living or bedrooms is below 60 % (recommendation of the United States Environmental Protection Agency EPA). In the bathroom, kitchen, or cellar, a slightly higher humidity level is acceptable. Too high humidity over a long time can result in the growth of mold, which poses a health risk. Too low humidity can be a sign of overheating and can also cause health risks, such as nasal dryness in winter.

Note that humidity measured by GROHE Sense on the floor can vary from a measurement taken by another device placed at a different location in the room. The humidity measurement can be also influenced by the surface material where GROHE Sense is positioned.

RECOMMENDATION WHAT TO DO

To reduce the relative humidity, you can try various things:

• Open the window during/after showering/bathing
• Use the exhaust duct or open windows when cooking, washing, etc.
• As a last resort, you can use air conditioners or dehumidifiers to improve the situation

To increase relative humidity place cups with water in the room close to radiators or use a vaporizer or humidifier.

The lower/upper humidity thresholds are settings you can adjust yourself for each device. Reduce the lower humidity threshold if you set it too high, or increase the higher humidity threshold further upwards if you set it too low.

HIGH / LOW TEMPERATURE AND FROST RISK

EXPLANATION

Room temperature is measured on a continual basis, once per hour. As long as the values stay within the set thresholds, the readings are updated in the GROHE Sense app once per day. If the temperature reaches a value above or below the set threshold, you will be automatically notified by the app.

Furthermore, GROHE Sense has an automatic default frost risk warning. This frost risk alarm is triggered as soon as the temperature drops below 3 °C.

Note that temperature measured by GROHE Sense on the floor can vary from a measurement taken by another device placed at a different location in the room. The temperature measurement can also be influenced by the surface material where GROHE Sense is positioned.

RECOMMENDATION WHAT TO DO

Check if your heating system and radiators are working properly, especially if you leave your house for an extended period of time. Check regularly the basement and rooms not often used and make sure that the temperature there stays within reasonable levels.

The lower/upper-temperature thresholds are settings you can adjust yourself for each device. Reduce the lower temperature threshold if you set it too high, or increase the higher temperature threshold further upwards if you set it too low.

DATA AND BATTERY NOTIFICATIONS

DATA TRANSFER IS NOT POSSIBLE

EXPLANATION

GROHE Sense connects to the Wi-Fi network to transmit the measurement data once per 24 hours, in several attempts. If the Wi-Fi connection cannot be established even with multiple attempts, you will receive this notification.

This user guide is applicable to the following products: 22500LN0, 22502LN0, 22502LN1, 22503LN0, 22504LN0, 22505LN0, 22505LN1, 22513LN0, 22517LN0, 22518LN0, 22519LN0, 22520LN0, 22594LN0, 22597LN0, 22601LN0, 22602LN0.

Definition of selected terms in the document:

• GROHE defines a pipe burst as a complete hole or a crack in the downstream piping system, resulting in unintended disposal of water with close to maximal flow rate. Pipe burst detection depends on the general water usage profile, therefore time lag to shut off can vary significantly. During that time water might be disposed of. Achieve higher detection speed by combining the installation with GROHE Sense in critical locations.

** A water system test is conducted once every 24 hours. Pipe material, volume, and other piping system characteristics can impact the result. Micro leak detection is limited to the cold water system in most cases. Combine with GROHE Sense to monitor potential humidity increases over time.
