Aqua-Scope AQSWIE01 Operating manual
Aqua-Scope Water
Monitor
SKU: AQSWIE01
Version: 1.0.4
Product Description
The Aqua-Scope Water Monitor records consumption of water in the home and it detects damaging
water leakages. The device applies several advanced signal processing analyzing water pressure
waves traveling inside the pipes of the house water system.
The device has two wireless communication options. When connected to your local WIFI network it will
send all sensor data and alarms to the Aqua-Scope Cloud and receive commands the same way. Your
mobile app can access the data and presents current and historic values and events. When connected to
a LoRaWAN network all data and alarms will be sent to your LoRaWAN network of choice. You can
operate the device with WIFI or with LoRaWAN connection or you run both connections in parallel.
A single sensor can monitor the whole home or apartment and additional peripheral devices such
as Valve Motors or Flood Sensors can be assigned to the monitor to enhance functionality.
While installation in single-family home will provide water consumption for the whole home, the
consumption metering in multi-family homes depends on the way the water pipes are installed. Leak
protection functions such as Pipe-Check or monitoring of pressure anomalies will work regardless of the
design of the home.
Installation Requirements
The Aqua-Scope Water Monitor watches the water pressure and water pressure waves (water noise) of
the home water installation system. The Aqua-Scope water microphone must be connected to the pipe
system at one single point in the home. Ideal connection points are edge valves located below sinks or
beside toilets. Alternatives are 1/4 inch revision openings on pressure reduction valves, shut off vales or
other installation gear. It is recommended to find a place as low in the home as possible (ideally
basement or first floor) but it is important to find a place 'after' the Pressure Reducing Valve PRV (The

main shut off valve is typically positioned before the PRV and hence the water microphone shall not be
installed on this valve).
Further requirements are:
Next to the device is mains power for the USB power plug.
The device expects a Pressure Reducing Valve (PRV)
installed in the home. The presence of a PRV is detected
automatically. If no PRV is present the device will still work
but the functionality is limited. Please refer to the manual
section 'PRV Impact' for details.
The place of installation needs reasonable coverage by your WIFI network of choice or by a
LORAWAN network.
Mechanical Installation
To make it short and easy – the video on aqua-scope.com/install explains the installation of the Aqua-
Scope Water Monitor step by step:
1. In case there are two edge valves under the sink, please identify the cold-water supply. Just open
hot water and check which valve warms up.
2. Close the faucet and close the edge valve by turning clockwise.
3. Remove the metal hose from the edge valve using the 19 mm wrench supplied. You may want to
have a towel on hand to catch the water leaking from the end of the hose.
4. Mount the T-shaped connector on top of the edge valve and fasten it using the 19 mm wrench.
5. Connect the metal hose to the upper end of the connector
and fasten it using the 19 mm wrench.
6. Screw the Aqua-Scope microphone into the side opening of
the connector and fasten it by hand. There is no need to
make it super-tide.
7. Re-Open the edge valve by turning the knob anti-clockwise.
8. Please check all three connections for some seconds that
there are no leaks.
9. Attach the Aqua-Scope to a suitable location using double-
side tape and plug the microphone into one of the two
sockets on the main device. Attach the optional water
contact sensor to the other outlet if desired.
10. Power the device using the USB Power Plug. Please use the
power supply provided within the scope of delivery. This
very power supply has very low distortion factor required for precise measurements of pressure.
Reset to Factory Default
The factory default is indicated by a green/red blinking LED. To return to factory default push the button
right after the initial buzzer beep (but not earlier!) and keep it pushed for 5 seconds. 4 short beeps will
help you count. After 5 seconds you will see three short green LED pulses with a low-frequency sound.

Now release the button! The recessed round part on the middle of the device is the touch button.
This process will delete all device and network settings.
WIFI Setup
Download the App “Aqua-Scope” from your App store and register yourself as new account with
email and password. You may want to use the QR codes above for a convenient access to the store.
Follow the instructions on the app. For all subsequent setups of Aqua-Scope Water Monitor please choose
the option “Setup new Monitor” in the Configuration menu of your mobile app.
If you don’t want to use the Aqua-Scope Mobile App you can also setup the device using any standard
web browser. Please refer to the manual section “Web Browser Setup” for details.
Part of the step-by-step guidance in the mobile app is to read your water meter and insert the current
water meter value into the app. After few weeks you will receive a push notification on your mobile
phone to redo this process ('Configuration' ->' Water Meter'). This will help to further enhance your water
consumption display accuracy.
Use it with Telegram
Aqua-Scope offers a Telegram Channel Bot to receive alarms and other information and to control
the device. Just use your mobile telegram application and subscribe to the channel Aquascope.
Now you need to subscribe to your device using the telegram command /connect device_id
nickname . You may want ot use the nickname to shorten further commands but its optional. The menu
buton of the channel tells you about further commands and functions.
Add more peripheral devices
The Aqua-Scope Water Monitor can act stand alone in connection with the Aqua-Scope cloud and your
mobile app or it can control further peripheral devices using a dedicated local LORA based wireless
network. Its recommended adding at least one Aqua-Scope motor servo (for ball valves or gate valves)
to shut off the water in case of an emergency or to support certain tests. You can add up to 10 additional
wireless Aqua-Scope water-contact sensors further protecting your home from water damage caused by
spillovers. Please refer to the manual of the water-contact sensors for further information.

Pairing with the LoRaWAN Network
The device supports LoRaWAN Class A and OTAA activation. Setting configuration parameter #3, Bit 0 =
1 allows changing to Class C. Reboot of the device is needed after the configuration value was set.
Operating the device requires sufficient LoRaWAN coverage from your LoRaWAN provider of choice. Your
LoRaWAN service must register the new device before the OTAA operation. LoRaWAN OTAA requires
three device-specific keys for this process:
Device-EUI (unique key to identify this device)
Application-EUI (unique key to identify the service of this device)
App-Key (unique secret key to secure network connection setup)
You find all three keys printed out as label printed out inside the package. Furthermore, you find a QR-
code with the Device-EUI right in the device.
Using the service http://io.aqua-scope.com/lora/keys.php you can download the complete set of keys
plus additional device information.
During pairing the LED will blink red/yellow. Once connected successfully the LED will glow green
indicating normal operation.
TTN Integration
The Things Network (TTN) is a free community based LORAWAN network with
global reach. If there is a TTN Gateway near your home you can use the water
sensor without any further hardware If no – may be this is a good reason to
join the community with your own gateway.
After the registration of the device with TTN please use the “HTTP Integration”
to forward all data to ‚https://io.aqua-scope.com/lora/in.php‘. Convenient
access for test purposes is possible using ‚https://io.aqua-scope.com/lora/ui.php?dev=DEVICE_EUI‘. The
link ‚https://io.aqua-scope.com/lora/lora.zip‘ allows downloading the scripts for change, inspection and
further use on own server and integrate the data into your own application.
Please note that the mentioned scripts can only be used for devices from Aqua-Scope. Device EUIs from
other manufacturers will not be processed.
Functions and Usage
Users and Installation Manual: Aqua-Scope Water Monitor (AQSWIE01)
Copyright © 2022 Aqua-Scope Technologies, Sakala tn 7-2, 10141 Tallinn, Estonia, www.aqua-scope.com
The Water Monitor has a variety of different functions that require certain configuration values. The
default values will work in most cases but you may want to double-check and verify the settings in the
mobile app under menu item "Configuration".
Water Consumption
The device will report each consumption of water including the duration plus the consumed amount of
water.
Ambient Sensors
The current water pressure, the ambient temperature, and the incremental water consumption since the
time of the last report is sent every 15 minutes.
Leackage Detection
To detect leaks some water must have escaped from the water system. Hence, leak detection does not
protect you from leaks but minimizes the damage of leaks. Damage happens if a certain amount of
water has enough time to impact construction material and furniture.
The diagram above shows the relationship between the speed of water (in liters/minute) and the time
this water flows out. The thick curve marks the area where damage will happen (about 10 liters of water,
one full bucket). The required reaction time to a detected leak depends on the speed of the water. For
micro leakages with very low speed of water (point 1 in the diagram) its acceptable to act after few days
or even weeks while a fatal burst of a pipe requires a reaction within few seconds (point 2 in the
diagram).
Aqua-Scope uses different techniques to identify leaks in four different scenarios (A1 - A4) characterized
by their speed of water. The lines between the area are determined by calibration. After initial calibration

the are constantly are re-adjusted to adapt the device to changing conditions of the water system. The
four sub-areas result in different alarms because the user action on these alarms may be different.
All normal water outlets in a home limit the speed of water. Even parallel consumption of water will
not result in speed of water beyond a certain level. In case the system detects a very high speed
of water a possible root cause is a bursting pipe (Section A4). Depending on the measured speed
of water the Aqua-Scope will issue a Heavy Flow-Alarm after few seconds. Please note that an
interruption of the water supply or a manual shut-off of the water will result such this alarm type
too since the Aqua-Scope Water Monitor must assume that the water disappeared somewhere.
The „Usage“-scenario (section A3) is defined by speeds of water typically for normal water
consumption of toilets, appliances, or faucets. Two thresholds define the alarm condition:
Max time in seconds, factory-default is 900 s = 15 m
Max amount of water in liter, factory-default is 200 liters
Exceeding these thresholds will cause a Usage-Alarm.
Additional protection is provided by the external wired water contact sensor, connected to one of
the two sockets of the Aqua-Scope. This will recognize e.g. spillovers or other loss of water. A
Flood-Alarm is sent out in this case.
The most dangerous and most common type of leaks are caused by a chemical reaction in the
water pipe leading to small orifice, also called micro-leaks (section A1). Since these orifices are
very tiny in the beginning, they are usually not seen. However, these very tiny leaks indicate a
much larger problem later on. The device has a built-in process to detect these small leaks. It is
called Pipe-Check. It requires to shut off the water for about 3 minutes. The application controls
this process by shutting off the water automatically (or advise the user to manually shut off before
triggering the pipe check). The completion of the pipe check is indicated with an uplink status
command or in case of a problem a Pipe-Check Alarm. The alarm includes the estimated speed
of water in ml /min plus the estimated elevation of the leak relative to the elevation of the water
microphone.
The “Drip”-scenario (section A2) defines flow speeds between about 100 ml/m and 2000 ml/m.
This is still quite low, but a Pipe-Check would come too late here. Hence, this range is monitored
permanently and detected leaks or dripping faucets will cause a Drip-Alarm within minutes.
Additional Monitoring
The system is permanently monitoring the water to detect pattern indicating a jamming toilet flap.
In this case a Jamming-Alarm is issued.
If the water pressure is too high the pipes may be damaged in the home. The Aqua-Scope will
determine automatically the highest acceptable pressure and report an Overpressure-Alarm if
this threshold is exceeded.
The internal temperature sensor allows issuing a Frost-Alarm when a certain threshold for frost
danger is hit. The factory default value for this threshold is 4 °C.

PRV Impact
An installed pressure reducing valve (PRV) is common in almost all contemporary European home water
installations. Without PRV the Aqua-Scope Water Monitor is still applicable but some functions are limited.
Working: Pressure Monitor, Temperature Monitor, Flood-Alarm, Frost-Alarm, Overpressure-Alarm,
Micro Leak Testing
Not Working: Drip-Alarm
Less Precise: Usage Alarm, Water Consumption Metering, Jamming-Alarm
Attention: If your water system has a PRV installed the Aqua-Scope Monitor MUSt be
installed after the PRV (between PRV and the individual outlets).
Alarm and Alarm Clearing
All alarms are indicated by
a buzzer sound on the device,
a red LED blinking on the device,
a warning display on the home page of the mobile app including the
time stamp, reason of the alarm and a hint how to remedy the
situation,
a push notification on the mobile phone that has the native app
installed (when connected to WiFi).
a LoRaWAN alarm message sent to the LoRaWAN Application Server
(when connected to LoRaWAN network)
Alarms are cleared automatically if the reason for the alarm disappeared.
They are kept as notice on the mobile phone app but with green color to signal that the root cause of the
alarm was removed.
Only the Flow-Alarm must be cleared by a wireless command or pushing the single button on the device
even when the sensor does not have contact with water anymore. The recessed round part on the
middle of the device is the touch button.
If no alarm is cleared pressing the button will issue a heartbeat signal sent to the LoRaWAN network
server if the device is connected to a LoRaWAN network.
