Energy Management Tools That Help You Save More and Work Less

No Monthly Subscription

Capture more savings from your energy metering projects with a metering system that has no subscription fees. We want you to take two steps forward and no steps back when it comes to your energy efficiency improvements.

Real-time User Interface

The eGauge UI displays your energy meter data on a webpage in real-time. You can access the UI with a LAN connection or through our proxy server. Watch as your energy profile changes every second, revealing potential problems that you could never discover with a simple utility bill.

Active Alerts

Carry on with your daily routine while eGauge active text and email alerts work for you to find excess equipment usage, unexpected demand charges, loss of renewable energy production and other costly failures. You can define alerts that trigger for virtually any threshold value.

The eGauge Hardware

Meter | Data Logger | Server

Each eGauge unit combines an energy meter, data logger, and a web server. This powerful combination lets you measure, store and retrieve data directly from the device or from a remote location. Not only does it calculate power (V, A, VAr, kWh, etc), but also data from optional sensors that assess flow rate, temperature, wind speed, and more. You can view historical and live data for up to 30 years with the unit’s convenient user interface (UI). The UI can be accessed on a local network or via the internet from a computer, tablet, or smartphone. Once connected, you have access to real-time values, long-term reports, an interactive graphical interface, and many other tools. The best part is that you pay nothing for the user interface because you retrieve data directly from your own eGauge hardware, not a cloud or 3rd party host.

User Interface

Data | Graphics | Alerts

The eGauge UI presents a powerful and straightforward graph to visualize energy data. The graphical view is highly customizable and can be set to display (or hide) any number of monitoring points. The monitoring points are shown with user defined time periods so it's easy to analyze data ranging from minutes to months, or even years. Users can create custom views which present data that is formatted for a particular need and removes irrelevant information. The graph is a staple of the UI because it can present highly granular data in an understandable way.

What is Power Factor?

Power factor is the ratio of real power (kW) to apparent power (KVA). This ratio can be a value from 0 to 1, and it indicates how efficiently an AC circuit is using electricity, with a value of 1 representing high efficiency. The third type of power, called reactive power (KVAr), causes electronics to be inefficient and draws the ratio closer to 0 by creating a difference between real power and apparent power.

Recently published CPU exploits

This is an advisory that all eGauge models (eGauge2, EG30xx, EG4xxx) are NOT VULNERABLE to the recently published CPU exploits (Spectre and Meltdown; CVE-2017-5753, CVE-2017-5715, and CVE-2017-5754). We advise checking other computers, IoT devices and smart phones for security updates related to these issues.
