Device Configuration

What password do I use to save a change to the settings?

Provided you are connected to the device directly through your LAN (not through egauge.net) you can enter username "owner"' and password "default''. You can ensure that you're directly connected to the device by clicking the "LAN Access'' link at the top right of the device web pages.


When I try to save settings, I get the message "Settings not saved: Error: Sorry, you are not authorized to make this change."
This occurs when the username and password entered is valid, but denies the configuration change. This will happen for one of two reasons:
  • The user you authenticated as does not have privileges to save settings. You can see your privileges in Settings -> Access Control.
  • The user you authenticated as has privileges to change settings from the LAN only, and you are connecting over the proxy server (eg, http://egauge9999.egaug.es) or you are not on the same subnet. Click on LAN Access from the upper right-hand link menu to connect directly to the eGauge. This will not work if you are on a different network or subnet.
If you need remote administration enabled so you do not have to go through LAN Access, you may enable it using eGuard Manager or submit a request to support@egauge.net with the device name (and MAC address if the device is not registered to you).

When I click on "Grid", why does it show green when I am using power but red when I am back-feeding?
Individual register lines will show green if they are positive, and red if they are negative. In eGauge convention, the Grid will show as positive when it is demanding power from the utility and red when it is pushing power back. This is not to be mistaken with the red "Power used" line and the green "Power generated" registers in the first row. If you wish to change the colors for a line without affecting the data recorded, you may use custom register styles to do so. Please see the FAQ entry, "How do I change the colors of my register lines?"

How do I change the color or style of my lines?
You may use custom register styles to change the color and line style of a register. This can be done by clicking on Settings -> Preferences, and pressing "Add Custom Register". You are presented with the choices:

Register    Which register should appear in the defined style
Color Color for the chosen register
Line Line style and thickness
Sign Whether to style the line for positive, negative, or both sign

What is the difference between a 16 register and 64 register device?
A physical register is a reserved section of memory that stores values associated with one point of measurement. Physical registers can store a variety of measurement types, such as voltage, current, kVA, and others depending on how the eGauge is configured. Note that there is not necessarily a correlation between the number of CTs installed and the number of physical registers used. For example, using one CT to monitor a 120V split-phase load or using three CTs to monitor a three phase load would both require one register. The primary difference between the 16 register and 64 register eGauge is the granularity of the stored data. A 16 register eGauge stores (from most recent data to oldest) ten minutes of data at one second granularity in volatile memory, one year of data at one minute granularity, and thirty years of data at fifteen minute granularity. A 64 register eGauge stores ten minutes of data at one second granularity, one year of data at one minute granularity, and six years of data at one hour granularity. Thus, the trade-off is between number of points that can be monitored and the granularity of the stored data.

Connectivity

What kind of BACnet functionality does eGauge provide?

A summary of eGauge's BACnet functionality is available on the BACnet section of the eGauge Overview page. The BACnet PICS Statement is available below in the DOCUMENTS section of this page.

My HomePlug adapter is connected to a Cisco Catalyst Ethernet switch and it stopped working. What do I do?

This answer applies only when a Netgear HomePlug 1.0 adapter is in use! With Actiontec adapters (or any Turbo-mode HomePlug adapter), there is no issue connecting to Cisco Catalyst switches. Also, this question only applies to professional-grade Catalyst Cisco products, not to Cisco home routers or switches.


Certain Cisco Catalyst switches detect excessive numbers of collisions on the port with a Netgear HomePlug 1.0 adapter and end up shutting down the port. When this happens, the bottom LED on the Netgear HomePlug adapter will go dark. Also, the switch's log file may contain error messages of the form:
Jan 6 19:41:46 192.168.1.15 1041767: 1041766: Jan 6 19:41:46.038 MST: %ETHCNTR-3-HALF_DUX_COLLISION_EXCEED_THRESHOLD: Collisions at FastEthernet0/14 exceed threshold. Considered as loop-back. Jan 6 19:41:46 192.168.1.15 1041768: 1041767: Jan 6 19:41:46.038 MST: %PM-4-ERR_DISABLE: loopback error detected on Fa0/14, putting Fa0/14 in err-disable state
To work around this issue, change the switch configuration to force full-duplex mode on the port. That is, turn off auto-negotiation and force the port into full-duplex mode, even though the HomePlug adapter advertises itself as a half-duplex device only. Alternatively, replace the HomePlug adapter with a Turbo-mode adapter (85Mbps).

Is it OK to plug the HomePlug adapter into a power-strip?
HomePlug adapters should be connected directly into a wall outlet. If that is not an option, it is possible to plug it into a power strip provided the power strip has no surge suppressor built in. Most power strips designed for computers have surge suppressors built in, so they are not suitable. Low-cost power strips are available at local hardware stores and generally work fine. Usually, non-surge suppressed power strips are called "relocatable power taps".

I can't connect to my device anymore, what should I do?

First, power-cycle the eGauge. See the answer to the next question "How do I power-cycle the eGauge?" for details on how to do this. Second, try unplugging the HomePlug adapter and then plugging it back in. This retrains the HomePlug-adapter and will often bring the device back.

Third, let's find out if the device can be accessed locally. We will use DEVNAME as a stand-in for the name of your device (e.g., for eGauge9999 or whatever the real name of your device is). Using a computer that is connected to the same LAN as the eGauge, open a browser and open one of the following two URLs, depending on the type of your computer:

http://DEVNAME
(on Windows-computers)
http://DEVNAME.local/
(on Mac or Linux computers)


If this URL loads and you get a graph that's updating, the eGauge is working fine and accessible through your LAN. If the URL does not load, check the following:

  • For the eGauge2 (Without built-in Ethernet port): Verify that the HomePlug adapter is plugged into a wall-outlet (NO surge protectors) and that all LEDs are (mostly) green. If you have a Netgear adapter, all three LEDs should be a steady green, except that the bottom LED may be flickering from time to time, indicating network traffic. If you have an Actiontec adapter, both the Power and Link LEDs should be mostly green, except for the occasional flicker, indicating traffic on the powerline or the LAN, respectively.
  • For the EG301x (Built-in Ethernet port, with HomePlug):  Verify that the HomePlug adapter is plugged into a wall-outlet and that all LEDs are on. If you have an Actiontec adapter, the PWR, LK, and ETH LEDs should be illuminated, except for the occasional flicker, indicating traffic on the powerline or the LAN, respectively.
  • For the EG300x (Built in Ethernet port, no HomePlug):  Verify both LEDs on the Ethernet port are illuminated (There will be both a green and yellow LED).
  • All Devices:  Check the Status LED on the eGauge. For EG301x, it should be green. If it is blue, it may indicate the the HomePlug speed is too low or the HomePlug link is interrupted. Blue is correct for the EG300x. If the Status LED is any color other than green or blue, contact eGauge support. Caution: The eGauge is installed in an enclosure with wires carrying high voltage. If you cannot see the Status LED without opening the enclosure, please have a licensed electrician check on the Status LED.

Fourth, let's find out whether the eGauge is connected to the server at egauge.net. Open a browser on a computer and try to load this URL:


http://DEVNAME.egaug.es/

If the page loads fine and results in a graph that's updating, your eGauge is fully operational. If the page does not load, it indicates a problem in your LAN environment. For example, the DCHP server on your LAN may be handing out incorrect Internet information. Please consult an IT professional for further help.


Can I connect a computer directly to the HomePlug adapter or Ethernet port on the eGauge?

You may use the complete guide, Tutorial 6: Directly Connecting to the eGauge

Here are the recommended steps to establish communication with an eGauge when the HomePlug adapter or eGauge Ethernet port is directly connected into the Ethernet port of a computer, and the eGauge is configured for DHCP:

1. Configure the computer's Ethernet-port to a static IP address of 192.168.1.11. The exact steps to do this vary with the operating system of the computer. For Mac OS X, this can be done by clicking on the Apple Menu's "System Preferences", then on "Network Control Panels". 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".

2. Power-cycle the eGauge main unit (turn off the breakers it is wired to, wait for 5 seconds, then turn them back on).

3. If you can see the Status LED of the eGauge, it should be blinking green/cyan or blue/cyan (cyan- light blue) now.

4. Open a browser on the computer, then type the address

http://192.168.1.88
into the browser's location bar, then press the Enter key.

5. At this point, you should be connected to the device.


How much data does the eGauge use?
The eGauge stores all data locally on the device itself, meaning it does not need to be connected to the internet and the proxy server for functionality. Because of this, data is only transferred when someone visits the device interface, or if data sharing is enabled to push data to a third-party server.

In most cases, any high-speed internet internet such as DSL, satellite, or cable are sufficient for networking multiple eGauge devices without any detriment on the rest of network traffic. Concerns may be raised on networks with limited data, such as cellular. In cases like this, if a browser window with the eGauge interface is left open, small amounts of data will be transferred indefinitely until the browser window is closed, and if data caps are exceeded, service may be disabled or overages charged.

Main device interface
The eGauge will use internet bandwidth when the eGauge main graph interface is viewed through our proxy server (ie, http://devname.d.egauge.net/ or http://devname.egaug.es/). If the eGauge is viewed locally (ie, http://devname/ on Windows, http://devname.local/ on Mac or Linux, or the local IP address), this will only use internal network bandwidth, not external internet bandwidth. On limited bandwidth internet connections such as cellular, accessing locally will reduce data usage.

When the main graph page of the eGauge is requested, it may load between 200 to 250 KB of data. Depending on how many registers are being loaded and the time period displayed in the graph, the eGauge may load an additional 10KB to several hundred KB. After the initial load, the eGauge will need to send instantaneous (second by second) data which may range from 0.5KB to 10KB per request. These numbers represent one browser window viewing the main graph page; additional browsers viewing the graph will each use this amount of data.

Pushed data
The eGauge has the ability to push stored data to a third party service. Push data usage is influenced by the number of registers, push interval, and any push options (such as totals or compression). As a rule, the smaller the interval, the more data is used. Depending on the configuration, push data usage can vary from a few megabytes to over a gigabyte per month. Beginning with firmware v2.03, push options gzip and deflate are available to compress the pushed data. This can significantly reduce the amount of data usage required for pushing data.

Testing/tracking data usage
Data usage varies widely based on a number of factors, each eGauge will use different amounts of data. Also, data usage will not necessarily remain constant from month to month. To see data usage on the main interface, you can use a browser such as Google Chrome, open the developer console (usually CTRL+SHIFT+J or F12), click the "Network" tab, and open a device interface. Every page request and its size will be visible in the Network tab.

You can get an idea of how much data will be used by uncompressed pushes (or polls) by making CGI calls to egauge-show, specifying different options such as interval. For example,
http://dev-name/cgi-bin/egauge-show?m&n=360
will represent a single push from a device set to push every 6 hours with no options. Similarly,
http://dev-name/cgi-bin/egauge-show?m&n=15&a
will represent one data push from an eGauge set to push every 15 minutes with totals as an option. For full details and parameters available, please see the eGauge XML API document.

What do the different LEDs on the HomePlug adapter mean?
HomePlug AV PWR500
LED Label Function Typical Behavior Other Behavior
PWR Indicates the adapter has power Green light No LED - no Ethernet communication for too long or not receiving power
LK Indicates a connection with the eGauge or another HomePlug AV adapter Blinking red light when communicating with the eGauge Blinking orange or green - possible connection with another HomePlug AV device
Off - no connection to any HomePlug AV devices
ETH Indicates an Ethernet line connection Blinking green light when transmitting data Off - may indicate an issue with network connectivity or a damaged Ethernet cable


HomePlug 1.0 HPE100T
LED Label Function Typical Behavior Other Behavior
Power Adapter has power and is connected to the eGauge or another HomePlug 1.0 device Green light when active, blinking green light when transmitting data Off - adapter is not receiving power, or cannot communicate to the eGauge
Link Indicates an Ethernet line connection Green when active, blinking green when transmitting data Off - issue with network connectivity or a damaged Ethernet cable

How do I check HomePlug communication speed?
If the eGauge interface can be accessed, it is possible to view the HomePlug communication speed. Navigate to the Settings page (http://DEVNAME.egaug.es/settings.html) and select the HomePlug option from the menu on the left. This will show the transmission speed (TX) and receiving speed (RX) of any HomePlug devices connected to the eGauge. The page refreshes every ten seconds.

Ideally, the HomePlug communication speed should be above 2.0Mbps for both TX and RX. A speed of 9.0Mbps is the upper limit for communication speed. Speeds below 2.0Mbps can result in connectivity issues and timeouts when attempting to view data on the eGauge. Note, the RX speed will show as N/A on older eGauge2 models.

Troubleshooting

How do I power-cycle eGauge?

In your breaker-panel, locate the breaker to which the eGauge is wired. This breaker should be labelled "eGauge Disconnect" or something similar. Once you locate the breaker, trip it so power is off, wait 5 seconds, then turn it back on. Normally, there is a single multi-pole breaker for eGauge, but in some cases there may be two or three separate breakers (one per phase/leg). In the latter case, turn off all eGauge breakers, leave them off for 5 seconds, then turn them all back on.


After upgrading my firmware, the web pages look all garbled. What's up?
This is the web browser's cache getting in your way. Please clear the browser's cache or use the browser's Reload/Refresh button to fix the problem. A document assisting with clearing the browser cache can be found under the tutorials section.

My summary totals are showing n/a or zeros, even though there is data in my graph!
If the Date & time when recording started from the Settings menu has not been correctly set during initial device configuration, it may cause summary areas to misbehave. Try setting the Date & Time when recording started a minute ahead, and view the summary area again.

What are some potential causes of HomePlug communication issues?
Note that a combination of the issues below may be involved with any communication problem. Also, there may be factors impacting eGauge/HomePlug communication not presented below.

GFCI Outlets

Almost all will cause issues, but will not necessarily prevent communication. A standard outlet can be installed; however this may not be allowed by code.


AFCI Breakers

Some arc-fault breakers will trip when the HomePlug is connected. As of right now, eGauge Systems has no data on which models have this issue. If you come across a model that causes issues, please contact the support department


Surge Protectors

Outlet-style and strip-style both cause significant issues with HomePlug communication by filtering out the HomePlug signal. More information is available here.


Phase Mixups

The eGauge communicates with the HomePlug over the phase connected to L1. If the HomePlug is installed on the phase connected to L2, this will result in significant communication issues. For more information, refer to the phasing document available here.


Transformers

In almost all cases, transformers will completely filter the HomePlug signal, resulting in a total loss of communication.


Wire Run Length

The effective range of HomePlug communications is approximately 50-100ft. Note that this distance refers to the length of wire in the walls, not a straight line between the eGauge and HomePlug. Longer wire runs will cause communication problems.


Other HomePlug Devices

Depending on the model, the eGauge either uses the HomePlug AV or HomePlug 1.0 communication protocol. Other devices using the same protocol can cause communication issues. Note that devices using the 1.0 protocol will not interfere with devices using the AV protocol, and vice versa. Pairing the eGauge and HomePlug together can often resolve these issues. Information on pairing the eGauge and HomePlug can be found here.


LED Codes

The color and pattern of the LEDs on the eGauge and HomePlug can help troubleshoot communication issues. A guide to the HomePlug LED codes can be found here. A guide to the eGauge LED codes can be found here.


Out of Date Firmware

There are certain types of communication issues associated with older firmware versions. Keeping the eGauge firmware up to date is recommended. If you are unsure about the firmware version your device is using, refer to the instructions on checking firmware version located here.


Shipping and Returns

Can I exchange my eGauge2 for a newer EG30xx, or upgrade the system?
The eGauge2 cannot be upgraded or exchanged for an EG30xx model. Both models, however, use the same CTs and firmware, and can share information over a network. This means you can add an EG30xx to your current eGauge2 installation if you wish to monitor additional circuits.

International

Are there multiple language options for the eGauge interface?
Yes. The interface can be translated into different languages by loading the eGauge page in your browser with the "lang" parameter and the appropriate language code. Your browser will remember this language preference.
http://DEVNAME.egaug.es/?lang=LANGUAGE_CODE
For example: http://egaugehq.egaug.es/?lang=es Available language codes include:
  • de - German
  • es - Spanish
  • zh_cn - Simplified Chinese

Other

How do I compare eGauge data with my utility bill?
On the eGauge dash-board, select the "Set time-period to display in graph" from the graph-menu like this:

graph-menu icon


In the "From" box, enter or select the date at which the meter was read in the previous month. In the "To" box, enter or select the date at which the meter was read in the current month. Click on "Set". The graph will be updated to display the chosen date-range. The "Summary for time-period shown in graph" now displays the amount of Energy Used, Energy Generated, as well as the Net energy used during that time-period. The utility bill's kWh-figure should correspond to the Net displayed.

How secure is eGauge?
The short answer: as secure as you want it to be! Our philosophy is that, as the owner of the device, you should have the say as to what the device is allowed to do and how it can be accessed.

For a more detailed discussion of security considerations, please review the white-paper available here.

Where do I find the MAC address for my device?

The eGauge has two MAC addresses. The first address is for Ethernet network communication (through the router or local area network). The second MAC address is associated with HomePlug power-line communication.

The Ethernet MAC address (for EG30xx) may be found:

  • On the back of the eGauge main unit
  • On the installation information sheet (if EG300x)
  • Displayed on the "Status" page (http://DEVNAME.egaug.es/status.html - requires username and password)
  • On the packaging sleeve included with the eGauge (if EG300x)

The HomePlug MAC address (for EG301x) may be found:

  • On the installation information sheet
  • On the packaging sleeve included with the eGauge

Either MAC address may be used for device registration or verification of ownership.


Can I extend the length of the CT leads?
Split core CTs can be extended with appropriately rated* twisted pair wire to cover much longer distances. STP (shielded twisted pair) is recommended, as it will reduce noise and interference. If you need to extend a CT wire farther than approximately 100 ft, contact eGauge support to see if a custom factor will be necessary in your software settings.

Appropriately rated CATV Ethernet cable can be used to extend up to 4 CTs.

*The insulation rating of the wire must be at least the maximum voltage of the system. For example, 430V rated insulation for a 120/240Vrms split phase system (240 times square root 2) or 680V insulation for a 480Vrms service.

Please see the CT selection guide for full details regarding CTs.

How do I check the current firmware version?
The current firmware version of a device can be seen by clicking View -> Device Status from the menu, or visiting http://DEVNAME.egaug.es/status.html. The small blue link next to the firmware version will open the firmware release notes page, where changes to the device firmware are tracked. We recommend updating the firmware on a regular basis.
