Power
ReMoni's power monitoring sensors provide a simple and effective way to measure and optimize energy consumption in various devices and systems. These IoT sensors offer real-time data, enabling data-driven decisions to reduce energy waste and costs. Easy to install, they help identify inefficiencies and optimize power usage, leading to significant energy savings.
PowerMoniSpot
Save resources and money by using PowerMoniSpot sensors for measuring and monitoring power consumption.
PowerMoniSpot is an IoT sensor enabling monitoring power consumption of different electrical devices and appliances. With the sensor calibrated it provides continuous data collection on actual power consumption, allowing to make data-based decisions with low-installation cost and time.
Features
- When calibrated PowerMoniSpot can measure actual power consumption.
- Alarms can be set up to warn about overconsumption, irregularities in consumption patterns or defects in the units.
- Continuous surveillance on the technical installations in the buildings.
- Simple and quick installation: clamp-on outside the cables without any damages.
- Powered with the battery with around 15 years lifetime.
- Transmitting real-time data collected from equipment/devices to ReCalc platform, where the collected data is presented and visualized via dashboards.
Use cases
PowerMoniSpot solution is ideal for precise logging and visualization of power consumption data, including operating times and usage patterns. PowerMoniSpot allows collecting and logging power consumption data, such as device activity (on/off), usage patterns and operating times.
- Lighting, ventilations, and cooling systems
PowerMoniSpot uncalibrated collects usage patterns of such electronic devices, helping identify inappropriate or excessive use. With the help of data collection and tracking, great power savings can be achieved.

PowerMoniSpot – Levels of calibration
Level 1 – Load profile (uncalibrated)
This is the default level of PowerMoniSpot.
This level measure and display the load profile, it displays the uncalibrated data and will not display current (ampere) or power (watt).
Note that the load must be single-phase (one live and one neutral conductor) or balanced across the phases if it is a multiple-phase system.
Level 2 – Manual calibration (ampere, volt-ampere)
This level works on any number of phases as long the loads are balanced across all phases, converting uncalibrated data into current [A] (ampere) or apparent power [VA] (volt-ampere).
To calibrate the PowerMoniSpot manually it is necessary to use a clamp-on ammeter to measure the ampere or knowing the exact specifications of the unit in either watt or ampere.
How to calibrate PowerMoniSpot: Level 1 – Load profile
1. Clamp a PowerMoniSpot on a cable connected to the unit you wish to monitor.
Note that the load profile is proportional to the current flow in the cable.
If it is a multiple-phased cable the load must be balanced across all phases.
In this guide, we’re using the unit “aircondition” as an example.
2. Go to recalc.remoni.com.
3. Select “Units” in the menu and choose the unit you want to monitor on the list as seen below. Make sure that the sensor ID matches the PowerMoniSpot’s ID. Click on the arrow next to “View” and select “Edit” in the drop-down menu.
4. In the top, select “Data.”
5. Now the Level 1 calibration load profile is visible.
How to calibrate PowerMoniSpot: Level 2 – Manual calibration (ampere, volt-ampere)
PowerMoniSpot can be calibrated to show consumption in both current (Ampere) and apparent power (Volt-Ampere). The load must be single-phase (one live and one neutral conductor) or balanced across all phases if it is a multiple-phase system.
1. Clamp a PowerMoniSpot on a cable and make sure it is connected to the unit you wish to monitor. In this guide, we’re using the unit “aircondition” as an example.
2. Go to recalc.remoni.com.
3. Select “Units” in the menu and choose the unit you want to monitor on the list as seen below. Make sure that the sensor ID matches the PowerMoniSpot’s ID. Click on the arrow next to “View” and select “Edit” in the drop-down menu.
4. In the top, select “Data.”
5. Choose Level 2 in the drop-down menu.
6. Click on the calculator to enter the calibration constant – remember to choose between current (ampere) and apparent power (volt-ampere) below “Calibrate for…” by clicking on the arrow.
Follow the instruction on the ReCalc platform.
Please note that the sensor needs to be calibrated again if you move it on the cable, or to a new unit.
What kind of power cables can be measured with PowerMoniSpot?
A PowerMoniSpot with Level 2 calibration can measure if the cable is single-phase (one live and one neutral conductor) or balanced across the phases if it is a multiple-phase system.
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 and is, therefore, a non-invasive measuring sensor.

PowerMoniMain – as a standalone sensor
PowerMoniMain provides ampere, watt, volt and power angle when installed.
One PowerMoniMain sensor has 15 channels. Each channel can monitor one phase.
This means the 15 channels can be allocated to fit the user needs, eg. one PowerMoniMain can measure five three-phased systems or 15 single-phase systems or a mix of both.
In short, this means you have up to 15 energy meters in this black box measuring only 178x178x75 mm. in dimension. The channels can measure consumption on any equipment or apparatus monitored by the PowerMoniMain sensor.
The CT-clamps measuring the current (ampere) is connected to the PowerMoniMain using the terminals on the left. Wires monitoring the voltage is connected to the terminals on the right.
The PowerMoniMain is wirelessly connected with the ReMoni Gateway, sending data onto the Cloud-based ReCalc.
For further technical information on the PowerMoniMain and CT-clamps, see the datasheet.
