Learning Objectives

After reading this article, you’ll be able to:

  • get insights in how Zens PuK IoT Visual works

  • how occupancy data from Zens is reflected in Workplace


How does Zens Smart PuK Visual work?

Both the use of the wireless charger and the motion sensor being triggered is regarded as a sign of occupancy.

If both are triggered, Workplace considers the location as being occupied.

  • Wireless Charging

  • NB-IoT communication

  • Occupancy sensor

  • iBeacon

Charging module

PuK iOT visual parts

  1. Place a phone that supports wireless charging on the charger.

  2. You’ll hear a “beep” within a few seconds. This beep indicates that charging has started. In addition, the phone will also show a charging indication on the screen.

  3. A message is send to the Workplace platform, indicating that occupancy/presence has been detected.

Motion Sensor

  1. Move in front of the motion sensor to trigger the sensor.

  2. A message is send to the Workplace platform, indicating that occupancy/presence has been detected.

 

How is Zens Occupancy data reflected in Workplace Live Views?

Upon the charger being used, the signal for Occupancy/Presence goes up immediately, and will remain actively sending updates to Workplace.

Upon a Motion sensor being triggered, the signal for Occupancy/Presence goes up immediately, but only goes down after a few minutes:

  • So as soon as occupancy is detected, a signal is send to the Workplace Platform, which will reflect in Workplace touchpoints' floorplans in near-real time: the location occupancy color goes from GREEN to RED almost instantly, but goes from RED to GREEN based on a fixed timer which cannot be shorter than 10 minutes.

  • This means that human motion can only trigger the sensor to go from '0' to '1' , and not the other way around.

Once the sensor goes up (meaning “presence detected”), it can't change its state faster than 10 minutes, which is why the default decay on the red icon lasts 15 minutes. The decay is actually nothing more than a clock counting down until the next refresh, regardless of the presence during that window.

In other words: The reason for using this decay is to indicate that the probability that the location is still occupied is lowering.

Decay Configuration options

Perhaps you would want to indicate in Workplace Live Occupancy View that if a Desk sensor has been triggered, the location is occupied for at least 2 more hours, so that colleagues and guests can go to lunch or drop by a meeting without having to fear that someone is clearing out their workplace? But at the same time you want to indicate that a meeting room has freed up as quickly as possible, so that it turns green (“available”/”not occupied”) and people can recognize this at a glance?

The Workplace back-end Studio configuration options have you covered: per room category, both the icon and the decay timer can be modified

For the reasons explained above: the timer can be set to anything higher than 15 minutes (15min being the minimum).

How does this reflect in Workplace Dashboards?

Even if you want to show your colleagues in Workplace Live Occupancy View that a desk is “occupied” while you’re actually jumping from meeting to meeting in other rooms, the data will show that the desk was only really occupied for some brief moments. Per default, data aggregation happens per 15 minutes.
