Virtual Sensors
Virtual sensors allow you to calculate the combined consumption of several sensors by adding or subtracting their values, to obtain the net consumption of an area, a floor, or a building.

Create a Virtual Sensor
- Click on "+ New".
- Choose the site and give a name to the virtual sensor.
- Select the unique sensors to include in the calculation and choose the operation (addition or subtraction) for each sensor.
- Save.

Visualization
The view of a virtual sensor is similar to that of a unique sensor, with a Graph tab that displays the calculated result (addition or subtraction) of the consumption of the selected sensors.
