EG4xxx LCD Manual

eGauge meters in the EG4xxx line feature an integrated LCD display which can be used to view data and make
changes to the device configuration. Navigation is handled through the small control toggle located to the left
of the CT ports. The control toggle has three potentials - left, right and pressed in. By default, the LCD scrolls
through a list of registers (the contents of this list are customizable) and also displays the device hostname
and current IP address.

To access the main menu, press in the control toggle. The following screen will appear:

Figure 1: All items in Main Menu view

The main menu has four options. However, the number displayed on a single screen may vary based on
orientation and font size. Simply scroll using the left or right toggle controls.

Status Bar

The status bar appears at the top of the LCD (main and sub-menus do not show the status bar). There are four
primary pieces of information displayed in the status bar, as shown below:

stat_bar.png

Figure 2: The status bar icons

Heartbeat indicator – alternates between full and empty indicating that the eGauge is running and the
display is active.
Connection type – shows the communication technology in use. There are four possible connection
types:
the_unknown.png - Unknown (generally shown immediately after reboot)
eth.png– Ethernet
hp.png– HomePlug power-line communication
wifi.png– WiFi adapter 
Connection Strength – Signal/link quality. A single dot indicates 0% signal. The taller the bar, the
stronger the signal.
Page – The active displayed page and total number available (active/total). You may scroll through
pages displayed by moving the control toggle left or right.

Registers

Registers is essentially the “default” state for the LCD. When this option is selected, the LCD will scroll
through every register configured in the eGauge device web interface under Settings → LCD along with
the device hostname and current IP address. The active page number is shown in the top right corner of the
display. Note that the registers displayed will vary from device to device, depending on configuration.

Info

The Info section contains device-specific data. This data may be useful for troubleshooting. As some of
this data may be sensitive (particularly the MAC address), it should not be shared with anyone other than
eGauge technical support and individuals who are authorized to make configuration changes to the eGauge.
The available information is summarized below:

Tools

The tools menu provides access to some basic eGauge utilities.

Settings

Certain settings can be modified directly through this menu. The Settings menu is broken down into three
subcategories – Display, HomePlug, and Wireless.

Display

LCD display settings are configured here.

HomePlug

HomePlug functionality can be accessed through this menu. Note that the “Join others” option will only
attempt to pair with HomePlug adapters or eGauges currently in join mode themselves. If no HomePlug
adapters or eGauges are present and in join mode, it will time out.

Wireless

If using an EG42xx model meter, wireless functionality can be accessed through this menu. When using
WPS, access to the wireless router is required.

Status – shows the status of the WiFi interface. This may take up to 30 seconds to load. 

Setup via AP - Activates the EG42xx access point for 60 minutes to allow for wireless connectivity to the meter interface. For details on connecting to the EG42xx Access Point please see: EG42xx Wifi Connection

WPS Setup – connects the eGauge to a router using WPS push-button pairing. To perform WPS setup, consult your router’s manual. Generally this process requires holding a button labeled “WPS” on your router between 1 and several seconds, then initiating the “WPS Setup” function on the eGauge. 

Disconnect – Reset the WiFi configuration, forgetting any networks it has been configured to connect to.

What do the different colors on the Status LED mean?

EG4xxx hardware features an LCD screen - as such, there is no status LED and the information below does not apply to EG4xxx hardware. Please see the LCD guide for more information when using an EG4xxx meter.

eGauge2 and EG30xx hardware features a front-mounted status LED which can convey useful information regarding device connectivity.

LED Blinking

GreenEG301x (Using HomePlug) and eGauge2: Device is connected to the eGauge proxy server and HomePlug speed is good (≥2Mbps).

LED Alternating Green and Cyan

EG301x (Using HomePlug) and eGauge2: HomePlug speed is good (≥2Mbps) but device was unable to obtain IP address from a DHCP server, and has defaulted to 192.168.1.88. Verify that a DHCP server is running or configure a static IP.

LED Blinking Blue

EG30xx (Using Ethernet): Device is connected to the eGauge proxy server.

EG301x (Using HomePlug) and eGauge2: Device is connected to the eGauge proxy server and HomePlug speed is marginal (≤2Mbps).

LED Alternating Blue and Cyan

EG30xx (Using Ethernet):  Device unable to obtain IP address from DHCP server. Verify Ethernet media connections, assign static IP if no DHCP is available.

EG301x (Using HomePlug) and eGauge2:  HomePlug speed is marginal (≤2Mbps) or nonexistent, device was unable to obtain an IP address from DHCP server. Verify communication between eGauge and HomePlug adapter.

LED Solid Green

EG301x (Using HomePlug) and eGauge2:  HomePlug speed is good (≥2Mbps) and device is not connected to the eGauge proxy server. Check that "Settings --> General Settings --> Proxy-server hostname" is set to "d.egauge.net". Contact an IT professional if there are continued problems connecting to the proxy server. See the eGauge Network Connections knowledgebase article for technical information on the eGauge's networking requirements.

Devices set to use a static IP address will show a solid green LED if HomePlug speed is good (≥2Mbps) and the eGauge can't reach the proxy server.

LED Solid Blue

EG30xx (Using Ethernet):  Device is not connected to proxy server, or there is no Ethernet connection to the eGauge. Check firewall settings and verify Ethernet port LED activity.

EG30xx (Using HomePlug) and eGauge2:  HomePlug speed is marginal (≤2Mbps) and device is not connected to the eGauge proxy server. Follow steps in owner's manual to improve HomePlug speed. All models:  Check that "Settings --> General Settings --> Proxy-server hostname" is set to "d.egauge.net". Contact an IT professional if there are continued problems connecting to the proxy server. See the eGauge Network Connections article for technical information on the eGauge's networking requirements.

Devices set to use a static IP address will show a solid blue LED if HomePlug speed is marginal (≤2Mbps) or the device is connected via Ethernet and the eGauge can't reach the proxy server.

Other Colors

EG30xx and eGauge2: In some cases, the Status LED may display other colors. This is most commonly observed immediately after a reboot, when the Status LED may flicker purple before settling into one of the patterns above. However, the Status LED may also show blinking red, which indicates the eGauge is overheating (ambient temperatures in excess of 158 degrees Fahrenheit). Should this happen, the eGauge should be powered down and allowed to cool, and steps should be taken to reduce the ambient temperature (for example, using a larger enclosure or installing a sun shield). The Status LED may also show solid red or solid orange, which indicates a hardware or software failure. This typically cannot be resolved onsite - contact eGauge technical support (support@egauge.net) for additional assistance.

Where can I find a HomePlug 1.0 adapter for my eGauge2?

The eGauge2 requires a HomePlug (PLC) adapter that uses the HomePlug 1.0 standard. Adapters that use the HomePlug AV standard (such as the TP-Link TL-PA2010) will not work with the eGauge2. eGauge Systems no longer stocks HomePlug 1.0 adapters, so they must be sourced through a third party.

HomePlug 1.0 adapters are no longer available new through any manufacturer. Used or NIB (new in box) adapters may still be available through third parties.

In general, any HomePlug 1.0-compliant adapter should work with the eGauge2. You will only need a single HomePlug 1.0 adapter, however it may be beneficial to purchase multiple adapters if available as HomePlug 1.0 adapters are becoming harder to find. As a general rule, adapters with a speed of 85Mbps or lower are generally HomePlug 1.0, while adapters with a speed of 200Mbps or higher are generally HomePlug AV. If you have questions about a particular adapter, eGauge Support may be able to assist with verifying whether the adapter will function as expected.

eGauge does not offer any sort of warranty on HomePlug 1.0 adapters sourced through third parties. Limited technical support is available. If necessary, eGauge2 devices can be replaced with a newer eGauge meter - any data can be copied from the original eGauge2 and copied over to the replacement. The same CTs can be used. Contact eGauge technical support for additional information on replacing an eGauge2 meter at support@egauge.net.

Encryption Support

EG4xxx meters have full TLS 1.2 support.

Proxy-server HTTPS support

Legacy meters do not support encryption between the meter and proxy server. However, encryption may be supported between the proxy server and the client requesting data.

HTTPS Support and certificate validation

eGauge2 and EG30xx meters have limited TLS 1.1 encryption support. By default, on modern firmware, client-side (meter) initated HTTPS requests (such as Data Sharing or Alert Service to an HTTPS URL) will attempt to validate the HTTPS certificate before sending data. Due to the older SSL library used on legacy meters, some certificates may fail to validate even if they support TLS 1.1. This may include the eGuard Alert Service.

Disabling certificate validation

Certificate validation must not be disabled if the information being sent is sensitive. Disabling certificate validation can allow for man-in-the-middle (MITM) attack if, for example, the local network the meter is using is compromised. The data will still be encrypted, but the meter will not be able to verify the destination's identity.

Beginning in firmware v4.5.5, The Modern Interface may be used to disable this certificate validation which can allow the meter to push data via HTTPS to certain services that support TLS 1.1 but which the meter cannot validate the certificate. To disable certificate validation, navigate to:

Setup → Network → Web-client, and toggle the "Disable certificate checking" option.

Setup → Network → Web-client

Disable certificate checking

In addition, the WebAPI may be utilized to configure the certificate validation via the /config/net/http/client/insecure endpoint
