TDI Sensors - Vemcount Firewall Guide
Purpose: This guide outlines the outbound firewall and network access required for TDI sensors to communicate correctly with Vemcount services.
Important: All firewall rules should be configured for outbound connections only. DNS resolution for the listed hostnames should also be allowed.
Required network access
Service | Hostname / URL | Port(s) | Purpose |
Data push (HTTP) | data.vemcount.com/ss/tdi | 80 | Transmission of sensor data to Vemcount using HTTP push |
Data push (HTTPS) | data.vemcount.com/ss/tdi | 443 | Transmission of sensor data to Vemcount using HTTPS push |
Time synchronization | ntp.vemcount.com | 123/UDP | Time sync for stable and accurate operation |
License validation | license.vemcogroup.com | 443 | License checks and validation |
TDI setup note: In the official TDI integration guide, Vemcount specifies Server Address:data.vemcount.com, Server Directory:/ss/tdi, and port 80 for HTTP or 443 for HTTPS. The guide also recommends using XML instead of JSON if special characters or spaces may cause push-format issues.
Additional setup notes
In the TDI sensor, go to Server Config and enter the Vemcount server details.
Use the sensor's Test Setting function to confirm that the push connection works.
If JSON formatting causes issues, switch to XML as recommended in the official guide.
