This installation manual can be applied to Spaceti Desk Presence Smart Stone (part number: SCP0L2P100, SCP0L2P110, SCP0L2P120).

Warning: For enabling all features of Spaceti system, it’s necesarry to have installed Spaceti connectivity HUBs in space and all sensors should be within a coverage. Please see Sensor Gateway installation.

List of steps:

  1. Choosing a suitable installation spot

  2. Cleaning the surface

  3. Placing Devices on top of the desks

  4. Adding into system

  5. Installation

  6. Validation

Installation process:

1. Choosing the proper installation spot

  • Choose an installation spot approximately 15-20 cm from the edge of the desk directly on top of the place where someone is sitting.

  • If there are any metal parts are on the bottom side of the table which could possibly block the PIR sensing cone, place the device in a way that will allow it to detect a person sitting at the desk. In front of or behind metal part, depending on the distance from the edge of the desk (according to images).

  • Metal parts of the table cannot block sensing cone of sensor.

  • Install one or two sensors and test their functionality. Try to avoid false positives and false negatives. If sensors work properly continue to next steps of installation.


  • Putting the device too close to the desk edge will lead to false positives caused by people walking near the desk.

  • Putting the device too far from the desk edge will lead to false negatives caused by the inappropriate position of the sitting person in relation to the sensor.

2. Cleaning the surface

  • Clean the surface with alcohol cleaner MEC3. Approximately 10x10cm around the spot for the sensor needs to be cleaned.

  • Allow the surface to dry.

3. Placing devices on top of the desks

  • Simply put the device MEC1 on the desk upside down so that the QR code can be easily scanned.

4. Adding devices into the system

  • Use Spaceti deploy app SW1 or Spaceti map editor SW2 for deploying device into the system.

Warning: Follow manual Map Editor user guide for detailed process of how to use SW1 or SW2.

5. Installation

  • Plug the platform MEC2 into device MEC1 according to images.

  • Position the platform in the way that the beak on the MEC1 part snaps into the recess of the MEC2 part.

  • On the platform, MEC2 and the bottom of the box MEC1 is cast text TOP and arrow. The two arrows must be facing each other. See image.

  • PIR lens on the device MEC1 must be oriented in a direction to the desk edge.

  • For XXX version of the surface use tie the zip ties around desired part of the table. Use the pliers to get device mounted tightly. Use clipping pliers to cut remains of the zip ties.

  • For YYY and ZZZ version of the surface remove cover of the proper sticker and stick the device under the table. Use at least 5s of hard pressure to the device to avoid falling down.

  • Turn the sensor on by releasing the battery contact blocking foil. Make sure the foil does not get stuck at the edge of the hole, it may cause the lead to get foil ripped. In case of faulty released foil replace the device for another one.

Note: The sensor can be “unbuckled” from the platform any time using TL1. Follow Spaceti Smart Stone uninstallation manual.

6. Validation

Installation needs to be checked after all devices are installed. This can be done in Spaceti dashboard.

  • “green” sensor - unoccupied

  • “red” sensor - occupied

  • “grey” sensor - not sending data

All sensors should be in the green or red state!

If sensor gray:

  • check that foil is removed

  • when the foil is removed, check if this specific sensor is sending messages (use Papertrail logging system). If no messages were sent there can be two causes of this issue:

  1. Device problem itself. Resolve it by changing this device for the new one. It is also should be redeployed in the Spaceti system!

  2. Gateway coverage problem. Try moving Gateway closer or add another one to this floor. For detailed information about the Spaceti monitoring system, follow Papertrail user guide user guide.
