This page explains how to add a secondary sensor to Lansweeper.
A Lansweeper installation consists of the Lansweeper Network Discovery Hub, one or more sensors, and an update service. A sensor is what actually scans your devices and sends scanned data back to the Hub. If you need to, you can add a secondary sensor to an existing Lansweeper installation.
Change Hub settings and grab the certificate
- On the machine that has your Hub installed, open Notepad or your preferred text editor as an administrator.
- In your text editor, open the following file:
Program Files\Lansweeper Network Discovery\hub\appsettings.json. - In the Hosting section of the file, replace "localhost" with the IP address of your machine. You can leave the HTTPS URL as is.
Install the new sensor
- Run the Lansweeper installer on the machine you want to use as your secondary sensor.
- Uncheck Install Hub and only check Install Sensor.
- On the sensor screen, submit the IP address of your Hub machine and your communication port, as found in your Hub's appsettings file.
Update the Hub URL in the appsettings files
Your new sensor should now be fully operational. You should see it listed in the Sensors menu of your Hub. However, you may need to update the Hub URL of your primary sensor and the Hub URL of your primary sensor's update service.
- Open
Program Files\Lansweeper Network Discovery\update\appsettings.jsonandProgram Files\Lansweeper Network Discovery\sensors\OT\appsettings.jsonon your primary sensor. - Ensure the Hub URL listed at the top of these files points to the correct endpoint:
- Sensor: https://[ip address of Hub]:[communication port]/Sensor
- Update: https://[ip address of Hub]:[communication port]/Update
- If the Hub URL isn't listed, update the URL in these files and restart both the Lansweeper OT Sensor and Lansweeper OT Update services afterward.
Double-check the Hub firewall
If your new sensor fails to appear in the Hub, ensure incoming traffic can reach your Hub over whichever port you configured as your communication port. The default communication port is 85, but you may have selected a different one in the installer. If incoming traffic over the communication port is blocked on your Hub server, remote sensors won't be able to communicate with the Hub.
The installer, by default, adds a rule to Windows Firewall on your Hub server to allow for communication to the Hub. However, if you are using custom firewalls, you may need to manually adjust your Hub server's incoming firewall configuration.
