Measurement point role
In the Planon application, a measurement point is distinguished by its role. Depending on the role, its measured data will or will not be used.
A measurement point can be either of the following roles:
• Primary measurement point
The measurement point's role is more or less synonymous with the function it is going to play:
◦ Primary A
Occupancy is derived from the measurement point readings.
When you select this role, the Display availability field on the Configuration tab is set to Yes.
 | Measurement point data will be taken into account for all possible occupancy-related graphs, if measured (Occupancy, Person count, Utilization, flow etc.). |
◦ Primary B
Occupancy is not derived from the measurement point.
When you select this role, the Display availability field on the Configuration tab is set to No.
| | Measurement point data will not be taken into account for all possible occupancy-related graphs, only for other measurement graphs such as environmental values. |
• Supplementary measurement point
This type of measurement point is introduced to process data correctly when using multiple connectors per location. When doing so, it is important to ensure that data of one connector is not blocking the data of another connector. This is achieved by using supplementary measurement points. Its data is merged into the primary measurement point (A or B) that is linked to the same location.
Supplementary measurement points are not used to record occupancy, but a set of environmental data:
◦ Free field 1/3 for vendor specific readings
◦ Battery status
◦ Carbon dioxide
◦ Humidity
◦ Light
◦ Noise
◦ Power level
◦ Temperature
◦ Radon
◦ Volatile organic compounds (VOCs)
◦ Particle matter (PM2,5 / PM10)
◦ Free measurement field 1-10
To define which data should be copied, you must link the data fields of the respective supplementary measurement point.

The readings of supplementary measurement points are stored at the primary measurement point. They are not stored on the supplementary measurement points themselves to ensure system performance.
• Secondary measurement point
Rather than occupancy, this type of measurement point is meant for providing auxiliary information, such as whether the waste bin is full or for testing new sensors. Consequently, its data is not collected and aggregated to the primary measurement point.
