The presence and occupancy virtual sensors enable you to understand how spaces in your building are used. These sensors have been made to understand long-term trends, not instant values. You can find this sensor at the bottom of the device page with other virtual sensors. The data is only shown when the opening hours for the building are enabled.

Presence is automatically enabled on any device with a CO₂ sensor. To view presence data, navigate to the Space and select the Presence graph, found at the end of the row with other virtual sensors. This graph displays the duration a room has been occupied, updating every five minutes to indicate whether the room was in use. The data is then aggregated into a total count of minutes the room was occupied.

When the Space height and area are entered, Occupancy is automatically enabled for any device with a CO₂ sensor, estimating the number of occupants in the room. Note that accuracy may be lower in buildings with natural ventilation due to irregular ventilation rates.

The occupancy graphs update every 5 minutes when the room is actively used and every hour during quiet periods. Historical data is adjusted a few hours back, reflecting updates based on recent data trends.

The underlying algorithm uses all sensors and some metadata to calculate presence and occupancy. It analyses the room over long periods of time to improve the virtual sensor’s performance. The algorithm also needs a minimum of 8 hours of data without gaps to show the virtual sensors.

The accuracy of the data depends on multiple variables, including:

As a result, the algorithm will work best for rooms where the air is mixed evenly for the device to register readings appropriately. Rooms with uneven mixing, such as meeting rooms with open doors or corridors will have less accurate results.
