WIFI Water Leakage Monitor

SKU: AQSWIE02
Version: 1.1.0

Product Description

The Aqua-Scope water leak monitor detects water leaks and records the temperature and water pressure. In combination with an Aqua-Scope remotely controlled shut-off valve, the system regularly searches for microleaks and shuts off the water if necessary. The user is then alerted via radio, both during such incidents and when pressure anomalies are detected. An additional wired flood sensor can be connected directly to the device. Furthermore, up to 10 additional wireless sensors can be distributed and connected throughout the building to detect water leakage and report it to the monitor via radio. The device consists of two parts:

• Main Unit (Monitor): Detects water consumption and leaks by analyzing pressure waves; Records temperature, water consumption, and water pressure continuously; Wireless alerts for detected leaks or when pressure or temperature thresholds are exceeded or not reached; Option to connect an additional wired flood sensor directly to the device.
• External Sensor Head: Connected to the water pipe, installed somewhere in the building at a 1/4-inch inspection opening, or with a provided T-piece under any sink at the angle valve.

Thanks to the excellent sound characteristics of water, a single sensor somewhere in the house is sufficient to detect water consumption and leaks throughout the entire building.

Control of the system is centralized through a mobile phone app using WiFi communication. Furthermore, data can be transmitted to an MQTT server or an HTTP 'webhook,' facilitating integration with modern Smart Home systems.

The sensor is powered either by an external power supply with a USB-C power supply or by an optional internal ER26500 battery (Bobbin Cell C). Both the sensor head (IP67) and the main housing (IP65) are waterproof and can be used outdoors or in particularly humid and/or dirty environments.

Installation

The Aqua-Scope sensor head must be connected to a single point in the house with the piping system. Ideal connection points are angle valves located under sinks or next to toilets. Other options include 1/4-inch access openings on the pressure reducer, shut-off valves, or other installation devices. It is recommended to choose a location as low as possible in the apartment (ideally in the basement or on the first floor).

Attention! If a pressure reducing valve (PRV) is installed, the Aqua-Scope monitoring device must be installed between the pressure reducer and the individual outlets. If no PRV is present, the device can be installed anywhere, but the accuracy of the measurements will be lower. Details can be found in the "Effects of Pressure Reducer" section.

1. If two angle valves are present under the sink, please identify the cold water supply. Simply turn on the hot water and check which valve warms up.
2. Close the faucet and shut off the angle valve by turning it clockwise.
3. Remove the metal hose from the angle valve with the provided 19mm wrench. Have a towel ready to catch the water coming out of the end of the hose.
4. Mount the T-shaped connector on top of the angle valve and secure it with the 19mm wrench.
5. Connect the metal hose to the top of the connector and secure it with the 19mm wrench.
6. Screw the Aqua-Scope pressure sensor head into the side opening of the connector and secure it by hand. It is not necessary to tighten it too much.
7. Open the angle valve again by turning the knob counterclockwise.
8. Check all three connections for leaks for a few seconds.
9. Attach the Aqua-Scope to a suitable location with double-sided tape and connect the sensor head to the main device. If necessary, insert the flood sensor into the audio jack.
10. Turn on the device using the USB-C power plug. Please use the included power adapter. This power adapter has a very low harmonic distortion, which is necessary for precise measurements. Alternatively, insert a battery.

Connecting to WLAN

Device Usage

Hardware

The above image shows the device with its connection options. The following connections or interfaces are present on the device:

• USB-C port: This port is only for power supply. The supplied USB-C power adapter is plugged in here. Please use the supplied power adapter from the manufacturer KTEC. Other cheaper power supplies may introduce noise to the device, negatively affecting sensor quality. The USB-C port is waterproof.
• The external sensor head is connected to the main device through a waterproof and screwable connection.
• Another external flood sensor head can be connected via the waterproof 3.5mm audio jack (included). This jack is also waterproof.
• On the back, there is the screwable battery compartment, also protected with a rubber seal against water ingress.
• In the center of the main device is the only button and thus the only local control of the device: It recognizes simple or multiple button press sequences:
  • Press and hold the button immediately after the first beep during startup for 5 seconds: The device will be reset to the factory state.
  • Press once briefly: A status message is sent to the network. If battery-powered, the device is awakened.
  • Press twice: Existing alarms (LED blinking red) will be ended.
  • Press three times: Currently not assigned.
• Directly below the button is the multi-color LED:
  • Yellow glowing or blinking in various colors: The device is booting.
  • Red/green blinking: The device is in the factory state and searching for a wireless connection. In this state, the internal web server and the Bluetooth interface are active.
  • Slowly breathing blue: The device is connected to the network and external power supply, in the rest or normal state.
  • Red blinking: Alarm active, and the device is connected to external power.
  • No LED: The device is either not powered or in battery-powered sleep mode.

Access to Sensor Data and Device Control

When the monitor is connected to the local Wi-Fi, its functions can be used through various communication methods (even parallel):

1. Mobile Phone App: You won't find the Aqua-Scope app in your phone's app store. We use a Progressive Web App (PWA, more at wikipedia.org/wiki/Progressive_web_app). To use it, open the website in the system browser (Chrome@Android or Safari@IOS) at https://app.aqua-scope.com. You can use almost all app functions in the regular browser. Android will offer to install the app on the device after a short time. On IOS, a shortcut of the website must be added to the desktop to receive push notifications if allowed.
2. MQTT Server: When configured accordingly, the sensor's status information is sent to the configured MQTT server. The MQTT service must be active, and your own MQTT server/port/login must be set in the device. More information can be found in the Aqua-Scope Developers Manual.
3. Own Web Service: Most smart home gateways allow the receipt and display of sensor data through plugins. More information can be found in the Aqua-Scope Developers Manual.

Measurement Values and Alarms

The device measures the pressure and temperature of the water in the pipe where the sensor is installed multiple times per second. On Anomalies the user is alerted.

The following alarms are possible:

1. One of the wired or wireless flood sensors has detected water. This is typically triggered by a leak near the respective sensor.
2. The water pressure has risen above the threshold set in the app or through configuration parameter 6. The reason for this alarm could be malfunctions of a pressure reducer or backflow preventer to the hot water system.
3. The water pressure has fallen below the threshold set in the app or through configuration parameter 7. The reason for this could be a pipe break; however, the water may have simply been turned off.
4. The external sensor is not connected to the main device.
5. The external sensor is connected to the main device but not connected to a pressurized water line.
6. The water temperature has either fallen below the value set in the app or configuration parameter 11 or risen above the value in the app or configuration parameter 16.
7. The Pipe-Check has detected a microleak. There is a separate chapter in this manual for 'Pipe-Check'.

The alarm is transmitted to the app and forwarded there via push notification and (configurable in the app) as an email or voice message. If the condition that triggered the alarm has been resolved, the alarm will be automatically cleared. It is also possible to clear the alarm by double-clicking on the monitor's button, even if the alarm condition has not been resolved. The alarm will then remain locked until the next power-on.

Sensor Data

The sensor measures water pressure and water temperature, and sends the values every 15 minutes, along with operating time, battery consumption, and battery voltage, via WLAN.

Communication with External Devices

The Aqua-Scope Monitor can operate as a standalone device, but its full functionality is realized when used in conjunction with other devices: additional flood sensors distributed in various locations and, particularly, a motor for shutting off water when needed.

Aqua-Scope offers compatible retrofit motors for different types of shut-off valves. These motors are installed directly on the shut-off valve without the need to interrupt water supply or cut into the water pipe. These motors can be removed without causing damage. The Aqua-Scope Monitor communicates with the motor through an internal LoRa radio system. LoRa was designed to communicate in challenging conditions such as basements and radio-frequency-difficult areas. Therefore, installing the monitor on an upper floor and a shut-off motor directly at the water meter in the basement is not a problem.

The motor needs to be paired with the monitor through the Aqua-Scope App. In the app's configuration menu, there is an option for "New Sub-Device." Only the QR code/ID on the device needs to be entered, and the motor is ready for operation. The QR code/ID must be 16 characters long and is located on both the device and the packaging.

• The app allows direct control of the motor through the "OPEN" and "CLOSE" buttons that appear.
• Configurable timers in the app enable you to automatically turn the water on or off at specific times on certain days.
• The motor facilitates an automatic Pipe-Check. More details in the "Pipe-Check" section.
• If configured in the app, the motor will automatically shut off in the event of detected leaks or other alarms.
• Of course, you can also control the motor directly at the device using the button.

Up to 9 additional external flood sensors can be paired with the monitor. This allows direct protection of sinks or other critical areas through a flood sensor. Pairing is done through "New Sub-Device" in the app, and the app automatically recognizes the type of device to be paired.

Pipe-Check

The detection of micro-leaks in the pipe system requires a special measurement method called 'Pipe-Check.' This process takes about 240 seconds, and during this time, the water system must be in a "rest" state, meaning no water withdrawal should occur. The 'Pipe-Check' should ideally take place at night as events like water withdrawal or water heating can disrupt the process without issues.

During the 'Pipe-Check,' water must be shut off. Therefore, it is recommended to install a retrofit motor that performs this task automatically at night. The time and days of the test can be set in the app as a timer (Configuration -> Timer) with 'Pipe-Check' as the action. If no retrofit motor is connected to the monitor, water can still be manually turned off, and the 'Pipe-Check' can be started manually in the app.

If the Pipe-Check indicates a micro-leak, there is no need to panic. In most cases, it will be a dripping faucet. If the result of a Pipe-Check shows a micro-leak over several days, it's time to investigate the cause. The alarm message provides further hints on where the leak may be located.

Battery Operation

The sensor can be operated with an external power supply, a battery, or both simultaneously. The status at the moment of powering on defines the device's operating mode. If mains voltage is present at the moment of powering on, the device will remain in power mode until the next status report (default every 15 minutes), even if mains voltage fails and a battery is inserted. The battery then operates as a backup.

If the sensor is started by inserting a battery, it will switch to battery mode. This means that some sensor functions are shut down to save power:

• The status LED remains dark.
• A local alarm is neither indicated acoustically nor by a red LED.
• The device responds only slowly to incoming commands (on average, about 10 seconds in power mode, up to one hour in battery mode).
• The device can no longer receive alarms from external wireless flood sensors.
• The sensor data is sent only hourly instead of every 15 minutes.
• If the device has LoRaWAN communication capability, it will attempt to join the LoRaWAN network only once (JOIN).

An estimate of battery life can be found in the app under "Devices". With a pressure reducer, the battery lasts about 8 to 10 years, without a pressure reducer in the water pipe, the lifespan is about 4 years.
