Pointgrab count areas aggregation in 1 Spacewell location

Learning Objectives
After reading this article, you’ll be able to:
Bring the data of Pointgrab sensors (that don’t form 1 count area in the Pointgrab Platform) to Spacewell and obtain an aggregated value in Live Floorplan + Dashboards
As mentioned in PointGrab installation location, A PointGrab Count Area is rectangular in shape and needs to be covered entirely by Sensor Detection Areas (Count Area smaller than sum of Detection Areas).
Yet in very particular cases, Pointgrabs may be installed in such a placement that it’s not possible to group them in 1 (rectangular) count area in the Pointgrab platform.
It’s not possible to link all Pointgrab devices, that are physically placed in 1 room, to 1 Spacewell location, since the data from 1 sensor will overwrite the data from the other sensors: per Spacewell Location there can only be 1 valid headcount value at a time.
This page describes a possible solution to keep the existing Pointgrab configuration on Pointgrab platform, but does aggregate the headcount values of the different sensors to 1 value on the selected location.
This way of working is based on the Motion sensor indirect utilization, see Utilization and Occupancy Matrix
The below description
details how to configure the Pointgrabs and location(s) for which you want to combine headcount data
explains how indirect utilization is calculated
assumes the setup for 1 location. If there are more locations concerned, just repeat the steps
In Pointgrab platform: create Count Areas
Configure your Pointgrab devices to Count Areas on the Pointgrab platform as detailed on https://spacewell.atlassian.net/wiki/spaces/KB/pages/492295
As always: if possible to create 1 larger Count Area, the better. So as soon as stitching is possible: go for it! The Pointgrab AI will be able to detect multiple readings of the same person, which might be counted double otherwise
In Workplace: Each Pointgrab count area needs to be a WORKPLACE object
Make sure each Pointgrab count area corresponds to a workplace object in IWMS and Workplace platform
IWMS "Workplaces" objects to be created in/under the correct ROOM object, which in turn should be in the correct room category -> make sure room and workplace categories are correctly mapped in Studio
Don’t map the Workplaces to a polygon on the floorplan, since you don’t want the individual values to pop-up. We’re only interested in the aggregated value on room level.
Make sure the capacity for meeting rooms is set correctly in Studio (ref Setting the capacity and thresholds of spaces) in you want to use the Quiet/Crowded/Overcrowded feature
Link each Pointgrab count area (“device”) to a workplace object through Add New Device, see PointGrab configuration | Deploy sensors in your Workplace tenant
By assigning them each to a different Workplace location underneath the “overlying Room”, their headcount values count towards the total Headcount on that overlying object.
In Pointgrab platform, both “KJblr1SCRlCU3GNkEd6rdA” and “M9nrKx6pQ3mn1NKy3z10fA” are Count Area IDs.
timestamp in below example is 18h local (Asia/Kolkotta) time

Remember to map each sensor to a different location!
When multiple utilization sensors are linked to the same location ID: incoming data will overwrite existing data.
In other words: when all are linked to the same location, there is no differentiation or utilization calculation possible.
How is utilization calculated in this case?
Occupancy
Presence on room level is true in case presence is true for 1 or more “workplaces”.
Utilization
For presence and headcount detected on “workplace” level: utilization/headcount will be calculated based upon the sum of the triggered seats.
So if 2 people each trigger a sensor linked to 2 different Pointgrab count areas, headcount will be 2.
Example
| Quarter 1 | Quarter 2 | Quarter 3 | Quarter 4 |
Pointgrab Count Area A, mapped to Workplace 1.A | 0 | 3 | 3 | 0 |
Pointgrab Count Area A, mapped to Workplace 1.B | 5 | 5 | 0 | 0 |
Room occupancy live floorplan | TRUE | TRUE | TRUE | FALSE |
Room utilization live floorplan | 5 | 8 | 3 | 0 |
Room utilization count timeslots (value used for reporting on Space monitor Dashboard) | 5 | 8 | 3 | 0 |
Impact
Having created Workplace objects, they will turn up in the dashboard
Since the calculation/aggregation is not done by Pointgrab (with Pointgrab AI being able to recognize redundancy of people being tracked by 2 sensors when stitched), there might be people that are counted double
