The starting date and time of the period that should be exported.
The ending date and time of the period that should be exported.
The time-interval between data points. A value of "1 day" requests that one data point is exported per day. A value of "1 hour" requests that one data point is exported per hour, and so on.
This option specifies the date and the time at which eGauge is considered to have started recording data. Any data recorded prior to this point in time will be ignored. Changing this value doesn't actually delete any data, so this point can be freely moved forward or backward, without fear of losing data. As a special case, this option can be set to the value "now" (without double-quotes) to establish the current date and time as the starting point. This is particularly useful after installing (or moving) eGauge since the data recorded prior to installation most likely is irrelevant and should be ignored.
This option specifies the geographic location at which eGauge is installed. For privacy-reasons, the coordinates are usually offset a bit so that they do not identify the exact site at which the device is installed.
For the latitude, positive values are nothern and negative values are southern latitudes. For longitude, positive values are eastern and negative values are western longitudes.
Clicking on the "map" link opens a new window that displays the currently entered location on a map.
Clicking on the "address lookup" link opens a new window to Maporama, which provides a convenient way to lookup the geographic location of an address.
This option can be used to limit public availability of the electric usage (consumption) data. Normally, this data is available at 1-minute resolution. When setting this option to any value other than "No restriction", usage data will be limited to the selected resolution. For example, with a setting of "1 hour", resolution is restricted to 1 hour. That is, all usage data will be available as 1-hour averages only, thus enhancing privacy.
Full-resolution data is always available to local users and authorized users.
The recommended setting for this option is "No Restriction". However, privacy- or security-concerns may warrant setting this option to another value.
This option specifies the hostname (or IP address) of the machine that is running the proxy-server. The proxy-server makes it possible to access eGauge at URL
These options specify how the individual measured power/energy-values get mapped to total usage and generation (production) figures. The most common configuration, where CTs are used to measure power coming in from the grid (utility) and from a solar inverter would be described with the following two formulas:
use = "Grid" + MAX ("Solar", 0)
gen = "Solar"
The first line says that total usage is the sum of the power
measured coming from the Grid and the power coming from the
Solar inverter, if it is positive (if the solar system isn't
producing any power, it's consumption is already measured as
part of the Grid power). Similarly, the second line says that
the generated power is simply the power coming from the Solar
inverter (note this figure may be negative if the inverter uses
power, e.g., when the sun doesn't shine).
In general, a formula consists of a sequence of terms, each of which may be added to or subtracted from the total figure. In addition, there are MIN and MAX operators, which allow taking the maximum or minimum, respectively, of a source (such as "Grid" or "Solar") and a constant value.
This option specifies the hostname of the eGauge.
Caution: The server at http:/// authenticates this name. Thus, if you change this name without notifying the operators at http:/// you will lose connectivity to http:/// and a service call may be required to restore connectivity.
This option controls whether the device uses manual settings for the network configuration or whether the settings are automatically obtained via the DHCP protocol. When this option is selected, the remaining network settings are grayed out, since their values will be obtained automatically.
This option defines the static IP address used by the device (e.g., 192.168.1.77).
This options defines the IP network mask used by the device (e.g., 255.255.255.0).
This option defines the IP network number used by the device (e.g., 192.168.1.0).
This option defines the IP broadcast address used by the device (e.g., 192.168.1.255).
This option defines the IP address of the gateway used by the device (e.g., 192.168.1.1).
These options define the IP addresses of up to four DNS servers. These servers are used by the device to resolve domain-names, such as "pool.ntp.org".
For security reasons, you need to first enter the existing password before being allowed to establish a new eGauge password. The factory-default for this password is "default" (without quotes).
Enter the new password here. Only letters and digits are allowed in the password string. The password should be at least six characters long and a word that is hard to guess, but easy to remember.
Reenter the new password here for confirmation.
Check this box if you want to be able to change settings from the Internet. By default, settings can be changed only when connecting from a computer that is on the same network as the eGauge. Please establish a strong password before enabling remote administration.
Click on this button to reset the "owner" password to its default. For safety-reasons, this will also clear the "Allow Remote Administration" checkbox.
