HTTP (HyperText Transfer Protocol) is the standard protocol used by a web browser to establish communication between a client computer and the meter’s web server.

You can view the meter’s webpages by entering the meter’s IP address on a web browser.

HTTP is not a secure communications protocol. To reduce the risk of security threats and help prevent unauthorized access to the meter and the network, configure the meter to always use HTTPS (HyperText Transfer Protocol Secure). The meter uses Ethernet port 80 for HTTP or port 443 for HTTPS.


HTTPS uses Transport Layer Security (TLS) encryption to secure the communications channel and protect exchanged data between the client and the server. When configured to use HTTPS, the meter uses the self-signed certificate installed on its webserver.
