Get to know your Hotspot and mini-hubs
The mini-hubs and hotspot are preconfigured to work together. The hotspot includes 1GB of free data service. If you need more data, you will need to sign up for a cellular service plan. For plan options, see GlocalMe ®1 .
If additional options are needed, you can add up to two nano SIM cards in the hotspot. Use a needle to pull out the available the SIM slots and insert the SIM cards.
Note: The hotspot included in this Kit does not support SIM cards that require PIN codes.
It is important to NOT pull the battery tabs on the sensors until at least one mini-hub is functioning properly. Failure to provide a LoRaWAN network before enabling the sensor can result in excessive battery drain.
Setting Up the Kit
Step 1: Fully charge the hotspot.
Step 2: Once charged, press and hold the hotspot’s power button (#11) for five seconds and wait for the device to boot.
Figure 2: Hotspot Buttons and Ports
Step 3: The hotspot will automatically log-in and connect to the GlocalMe service.
Figure 3: Automatic Login
Step 4: Once the hotspot displays the Wi-Fi name and Password, as illustrated in Figure 4 you can start setting-up the mini-hubs.
Figure 4: GLocal Login Complete
Step 5: Remove the cover plate on the first mini-hub. If necessary, attach the power adapter before plugging-in the mini-hub to a wall socket as shown in Figure 5.
Figure 5: Plug-in the mini-hub
Step 6: You will know the mini-hub is connected to the hotspot when the light on top turns green as shown in Figure 6.

Setting-up the sensors
In this kit, we are monitoring room or desk use, temperature, humidity and leaks. To this end, set up the sensors as follows.
Step 1: Grid Eye sensors are most effective if mounted on the ceiling or inside of a lighting fixture. Use the adhesive tape provided with the sensor to mount it in an appropriate location in your conference room. The Grid Eye sensor can be used to determine the number of people occupying a room.The sensor begins the count when motion is detected and provides an update approximately every 5 minutes thereafter.
Step 2: Window/Door sensors can be mounted on either side of the window frame or door frame, as illustrated in Figure 7.
Figure 7: Window and Door Sensor Placement
Note: The maximum allowable gap between a sensor and the corresponding magnet is 1 cm. Be sure to align the sensor side with the blue LED to the magnet face with the notch, as illustrated in Figure 8.
The Door/Window sensor will provide an indication of whether the door or window is open or closed.
Figure 8: Sensor/Magnet Alignment
Step 3: The Desk Occupancy sensor may be mounted on the underside of a desk using the double-sided tape provided. For best results, mount the sensor horizontally approximately 25 cm from the front edge of the desk, as shown in Figure 9.
Figure 9: Desk Occupancy Sensor
Note: The sensor will send a message when motion is detected. No additional messages will be sent as long as motion is detected anytime within succeeding 5 minute windows. Only after detecting no motion during a 5 minute period will it send a message indicating that the desk is unoccupied. Therefore, changes in condition may not be reflected in the dashboard immediately.
The daily Desk Occupancy statistics shown on the dashboard are calculated for the preceding day at midnight.
Step 4: To detect movement in a room, place the Room Occupancy sensor on a flat surface, such as a table or bookshelf. The Room Occupancy sensor behaves much like the Desk Occupancy sensor. The two have different parameters configured to account for the size of the space being monitored.
As with Desk Occupancy statistics, Room Occupancy statistics are only calculated for the preceding 24 hour period at midnight each day.
Step 5: To detect the temperature and humidity in the room, place the Temp/Humidity sensor anywhere in the room. To mitigate momentary changes in temperature due to opening a door or window, best practice is to place this sensor away from doors and windows.
Step 6: The IR blaster can control wall-mounted HVAC systems, heaters, televisions and any other electronic devices that use an infrared signal with a known Pronto code. A list of codes can be found at either of these two websites:
To use, place the IR blaster so that it is three to five feet from the item to be controlled, facing the item’s infrared receiver.
Figure 10: Face of the IR Blaster
Next, navigate on your browser to your kit’s dashboard. Click on the Environment tab on the left hand side. You will be presented with a screen which includes a place where the Pronto code can be entered as shown in Figure 11.
Figure 11: Entering Pronto codes for the IR Blaster
Step 7: For information about how to remove or replace the battery in any of the devices, scan the QR code below, or use the Chrome web browser to navigate to https://qrgo.page.link/iWxb.
Note: Regulations require that the battery must be removed from the device when shipping or flying by air. Alternatively, you can re-insert the plastic tabs to disrupt the battery current.
Changing the Mini-Hub Wi-Fi connection
If you do not want to use the hotspot provided Wi-Fi network, you can configure the mini-hub to use another network. To do so, follow these steps:
Step 1: Leaving the mini-hub plugged-in, turn off the hotspot.
Step 2: Using a computer, perform a network scan and select the open Wi-Fi network that starts with MiniHub-xxxxx where xxxxx are the last 6 digits of the mini hub MAC address, as illustrated in Figure 12.
Figure 12: Mini-hub network
Step 3: Once the computer is connected to the mini-hub, open a web browser and type 192.168.4 in the address bar.
Step 4: Edit the Wi-Fi SSID and Wi-Fi Password to reflect the new Wi-Fi network you want to connect to. Click Apply to save your changes.
Mini-Hub LED status indicators and button functionality
Table 1 shows what the various LED colors and blink patterns displayed by the mini-hub indicate.
Table 1: LED Status Indicators
- To switch from GW (gateway) mode to CONFIG mode, press the Setup button for 10 seconds.
- To reboot the mini-hub, while in CONFIG mode, press the Setup button for 5 seconds.
- To return the mini-hub to factory settings, (and delete the Wi-Fi and LoRaWAN Network Server credentials), press the Reset button for 5 seconds.
