You may use the complete guide, Tutorial 6: Directly Connecting to the eGauge
Below are the recommended steps to establish communication with an eGauge when the HomePlug adapter or eGauge Ethernet port is directly connected to the Ethernet port of a computer, and the eGauge is configured for DHCP. Note that Ethernet to USB dongles may require additional configuration not covered here.
1. Configure the computer's Ethernet port to a static IP address of 192.168.1.11. The exact steps to do this vary, depending on the operating system of the computer. For Windows, this can be done by starting the "Control Panel", then selecting the "Network and Sharing Center". For Linux, this can be done by selecting "System", then "Administration", then "Network Tools". For Mac OS X, this can be done by clicking on the Apple Menu's "System Preferences", then on "Network Control Panels".
2. Power-cycle the eGauge main unit. To do this, turn off the breaker(s), wait for 5 seconds, then turn them back on.
4. Open a browser on the computer and enter the address
into the browser's address bar (not the search bar), then press the Enter key.
5. At this point, you should be connected to the eGauge.
If the eGauge has a static IP address, modify the IP address set on the computer and the IP address used to access the eGauge in the steps above. For example, if an eGauge has been set to use a static IP of 10.1.10.50, the computer should be set to 10.1.10.11 and http://10.1.10.50 should be entered into the browser address bar.
