Meter: eGauge Core and Pro with WiFi

 Visit the online store page (EG4215 or EG4230)
Model: EG42xx

The EG42xx meter series contain embedded WiFi. Normally, the meter connects to a WiFi network to provide network and internet access. However, the meter can also temporarily act as an access point to allow a computer or mobile device to easily connect to it for initial setup or data access.

Both 15-port (EG4215) and 30-port (EG4230) versions are available.

See the eGauge Meter Comparison Chart for full side-by-side comparisons.

eGauge meters 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.
