About eGauge Systems

Overview

eGauge Systems LLC is a Boulder, Colorado energy-monitoring company focused on multi-circuit energy meters that combine metering, data logging, and local web access. Its products are used in residential, commercial, municipal, and industrial projects where owners need detailed power, energy, and solar-production visibility without ongoing monitoring service contracts.

Relevance to EnergyMeterHub

eGauge devices are especially relevant for buyers who want a more professional CT-based metering platform than app-first consumer monitors. The eGauge Core and Pro lines expose local web access and documented data interfaces such as Modbus, BACnet, XML, JSON, and CSV, making the brand useful for solar monitoring, submetering, facility metering, and Home Assistant-style local polling workflows.
