# Meter: eGauge Core ##### [ Visit the online store page](https://store.egauge.net/egauge-core "Visit the online store now!") ##### Model: EG4015 The eGauge Core (EG4015) is the Pro version of the EG4xxx meter line. It has 15 sensor inputs and no integrated HomePlug communication. See the **[Meter Comparison Chart](https://kb.egauge.net/books/egauge-meter-documentation/page/meter-comparison-chart-%28difference-between-core-and-pro-meters%29 "meter-comparison-chart")** for the different versions of the EG4xxx meter line and what is the best fit.

For the eGauge Core with integrated HomePlug power-line communication, see the [**eGauge Core Residential (EG4115)**](https://kb.egauge.net/books/egauge-hardware-product-pages/page/egauge-core-residential). See the **[eGauge Meter Comparison Chart](https://kb.egauge.net/books/egauge-meter-documentation/page/meter-comparison-chart-%28difference-between-core-and-pro-meters%29 "eGauge Meter Comparison Chart")** for full side-by-side comparisons.

The eGauge Pro 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.
