Frequently asked questions

We recommend installing the GateWay first – then the sensors.

ReCalc

Go to: https://recalc.remoni.com 

If you already have an account, enter your email and password.

To create an account click on: “Create new user & account”.  

Click on “Account settings” and then “User access” in the User profile

   

In the “User access” section, you can change the predefined roles and user settings.

You can e.g assign other users to "read only" access.

You can find it under the tab “view data”

Our ReCalc solution includes our self-learning alarm modules, to monitor your technical installations, in an easy way.

The alarm modules use artificial intelligence (AI) to generate alarms, warnings, service and maintenance information when needed – so you don’t have to do the work.

If you add your sensor in ReCalc and tap the icon "View Data" you can mouse over the graph to see which unit it measures. 

PowerMoniSpot can be calibrated to measure watt.

PowerMoniFlow and Heat are calibrated to measure temperature from the factory and no calibration is needed.

You have the following options:

    1. You can measure with a torque meter on the cable where the sensor is connected, what the maximum effect (watts) is.

    2. If connected to an electric motor you can read on the label, what the maximum watt is.

Once you have found the maximum watt by using one of the two methods, you divide it with the highest number you find on the graph.

That way you will find your calibration constant.

It is unfortunately not possible to change the unit type. If you have chosen the wrong unit type, follow these steps:

 

 

 

 

 

If you go to "Alarmgroups" you can choose between the different available alarms.

You can receive different alarms, depending on the type of sensor you are using and the unit you are surveilling.

First you have to add a new user under the "user section" and then select “account settings”

and then add a new user under “user access” by typing their e-mail.

Then you go to the settings icon and then add a user under “create alarmgroup” and press “save”.

 

Choose something that gets recognized easily, e.g. the location, name of building, customer name etc.

You can choose to receive alarms through notifications in ReCalc or by e-mail.

You can choose different levels of alarm severity to be received.

Go to the "Export data" section and choose between the different options and press “Export”.

“Base” is watt when PowerMoniSpot is calibrated. If your PowerMoniSpot is not calibrated, this field will be blank.

Gateway

It depends on the availability at the location of the Gateway.

Any 3G/4G Mobile Data connection, WiFi or LAN connection will do the job, since ReMoni sensors doesn't use much data. Our sensors have no minimum requirement of upload speed either.

 

On the gateway there is two light diodes, one red and one green. These diodes can help you determine what the error is.

An  or  icon indicates that the LED is off, an  or  icon indicates that the LED is on and an  or  indicates that the LED flashes.

 

 

Errorcode

Description

101

Everything works.

102

There is no connection to the internet, but the Accesspoint works.

103

There is an error between the Raspberry Pi and the Accesspoint or the Accesspoint is not connected. There is however connection to the internet.

104

There is an error between the Raspberry Pi and the Accesspoint or the Accesspoint is not connected, plus there is no connection to the internet.

Possible solutions to the errors

Errorcode

Solution

102

WiFi: Check with a smartphone, tablet or PC if a WiFi network with SSID “ReMoni GateWay” is visible. If it is visible follow the instructions “GateWay with WiFi”. If it is not visible, verify that the router your gateway is connected to, has got internet.

Ethernet: Verify that the ethernet cable is correctly connected to the gateway. The green LED on the ethernet connector should flash if there is connection. If not, try with another cable.

USB dongle: The light on the dongle should show a constant blue light. If there is no blue light, verify that the settings on the sim card is correct and there is data.

All: Restart the gateway by turning off the power, wait 20 seconds and turn it back on again.

103

Verify that the cable between the Raspberry Pi and the Accesspoint is correctly connected.

Try with a different cable.

104

Check the solutions for error codes 102 and 103.

105

Verify that the power is turned on and inserted correctly.

106

Verify that the SD-card is correctly inserted or try with a different SD-card.

In ReCalc, select Connections in the sidebar menu and look in the "connections" column, it should say “connected”.

When the LED on the mobile dongle is lighting blue, it is connected.

The SIM-card must be a mini SIM-card with a data plan. The type of sim-card is called M2M and has to be without a pincode. With normal use, a 2 Gb per month data plan is sufficient.

When you are beneath the section "Gateway" you press "view" and then you can see some options at the bottom of the page. It should show a list of the units that are connected.

If there are no units connected it would say "no sensors were found".

Sensors

All sensors are designed to last 15 years.

All ReMoni hardware has a two-year, limited worldwide warranty. This includes e.g. also the gateway.

Go to PowerMoniSpot to see the four levels of calibration

PowerMoniSpot can measure on single-phase when it's not calibrated with a PowerMoniMain.

Here is an example of what you can use:

PowerMoniSpot can’t be used for measuring inhomogeneous cables:

Removing large stand-by consumption can help you save both power and money.

Stand-by consumption can be estimated using power sensors on the parts of your installations you wish to monitor. If the power consumption stays high all day, there is probably a room for improvements.

PowerMoniSpot is a clamp-on IoT sensor that measures the current. It is not directly connected to the wires.

Take a look and see if a toilet is running or a tap is dripping. If so, it might be your leak, and a good thing is to avoid spilling water, and enable monitoring of more harmful leaks.
Try to close the main valve and see if the temperature reading off the pipe gets close to the temperature reading of the surrounding air.

If temperature reading of the pipe never reaches three degree Celsius of the reading of the surrounding air, your pipes are likely to have a leak.

Unittypes

Alarm setupIs added automatically for refrigerator unit types, or can be added manually on other unit types. No other setup is needed, however the temperature limits can be adjusted.

Alarmtype: Time between consumption, consumption levels, sensor status, total time active

Unittype: Water supply pipe

Sensors used: FlowMoniSpot

Solution: Are your pipes leaking?

Method: The sensor is mounted on the supply cable/pipe

Alarm setup:
Configurations: The included alarms are added automatically if you select the unit type "water pipe" when the unit is registered on ReCalc. No other configurations are needed

Alarmtypes: Time between consumption, leak, sensor status

  • Leaks: The leak alarm works by monitoring whether the water consumption goes to zero at least once a day. We can detect leaks from about one drop per second, corresponding to four liter per day.
  • Missing flow: If it's difficult to identify any flow in the pipe, you will be warned. Alarms are still raised if they are detected. Missing flow can be due to a sensor installation failure, or because the temperature of the water in the pipe is close to the temperature of the surrounding air, which makes the alarm less sensitive.
  • Missing data: If there has been a data drop out (big enough to make the leak detection invalid) no (false) alarms will be generated, and you will be warned.

 

 

Unittype: Water supply pump

Sensors used: PowerMoniSpot

Solution: Avoid clogged pumps and/or Does your pump run irregular?

Method: The sensor is simply clamped onto the power cable for the pump.
