Ports
The testo Saveris 2 WiFi data loggers use the MQTT protocol, which
communicates via port TCP 1883.
These UDP port approvals are also required:
• Port 53 (DNS name resolution)
• Port 123 (NTP time synchronization)
All ports must be able to communicate only externally to the Cloud. No bi-
directional port approvals are necessary.
Ping
The default gateway, which must be communicated to the probe via DHCP or
manually, must answer the PING request of the WiFi data logger.
Note
During the first configuration, it is possible to select whether DHCP or Static IP is
used (select expert mode for the corresponding information)
