Learning Objectives
After reading this article, you’ll be able to:
Start troubleshooting Browan sensor projects
Always learning from projects, this page addresses the most common issues encountered in Browan sensor projects.
Gateway connectivity
In most cases Hub connectivity issues are due to a wrong firewall configuration of the firewall: make sure to check
...
the List of IP addresses for outgoing traffic that is relevant for your gateway.
Make sure the gateway is configured as per the installation instructions.
See LoRa Gateways / Hubs installation guides
Sensor connectivity

All these cases were caused by installing the sensors before the hub.

Workplace Platform, either the gateway is not working or the sensors were installed/activated before the gateway was confirmed working.
In the first case (gateway not working): make sure the gateway is connecting to the platform by following above troubleshooting instructions.
In the last case (sensors not connecting to the gateway): remove the battery, wait for the capacitors to be drained (several hours, preferably over night), and insert a fresh battery.

Inaccurate data
Inaccurate data can have several causes.
...
Make sure to check:
Do the sensor

IDs and location comply with deployment?
Are the sensors linked to the correct floor/building?
Are the sensors places optimally according to the

...
How are the sensors placed?
Pictures help:What does a desk look like?
What is the orientation of the sensor?
Are the desks placed in

hallways? If so how wide is a

hallway?
What are the dimensions of a desk? Height, width, depth?
Are all sensors placed using the same method?

Check if Quality Assurance Occupancy/Utilization Sensor has been performed. In case of doubt: go through the steps again
Does each location have the correct number of sensors linked to it

Going on site
Things to take with you on site
- plastic badge/credit card/screw driver to open the sensor (check Tabs Sensors installation guides page on how to remove/change a sensor)
- spare batteries (1/2 AA 3.6V lithium battery)
- spare caps (if needed)
- tape and scissors (see Tabs Sensors installation guides for best practices on tape)
- computer with access to internet: Studio (health info) + Confluence (eg hub LEDs, installation instructions)
- paperclip (optional)
- microfibre cloth to clean surface
