GreenMeter

GreenMeter is a consumer energy-monitoring system consisting of a hardware device and an accompanying software platform designed to track electricity, gas, and water usage and to estimate associated carbon emissions in real time. It is aimed at households, small businesses, and energy auditors seeking actionable insight into resource consumption.

The hardware component installs near the main service panel. A current transformer clamp measures electrical flow, while optional sensor modules can monitor gas and water meters. The device streams data to the cloud, where software analyzes usage, attributes consumption to appliances when possible, and provides dashboards, trends, and alerts. Connectivity options include Wi-Fi, Bluetooth, and USB.

GreenMeter's software provides visualization tools, notifications, and goal-based budgeting. Users can export data, generate reports, and integrate with third-party platforms via an API or smart home ecosystems such as Home Assistant. Privacy controls include local storage or encrypted cloud storage, with user consent management for data sharing.

Origins: GreenMeter Technologies introduced the first model in the mid-2010s, with GreenMeter 1.0 in 2016. Subsequent releases, such as GreenMeter 2.0 in 2019 and GreenMeter Pro in 2021, added higher-precision sensors and expanded appliance-level estimation.

Reception and use: The product has seen adoption among eco-conscious consumers and energy consultants. Critics note that appliance-level accuracy depends on installation quality and data granularity, and that device-level inferences should be treated as estimates. Competition includes other home energy meters and dashboards.
