These systems offer a more efficient way to optimize how and when energy is used.

A HEMS connects with devices throughout your home, such as thermostats, lighting, and appliances, to automatically monitor and manage energy use. It responds to your schedule, habits, and even utility pricing to support meaningful energy savings while reducing emissions and promoting long-term sustainability.

In this guide, you'll learn how a home energy management system works, which features matter most, what components are required, and how these systems benefit you. We'll also explore how Vivint integrates HEMS features into its smart home platform and what to consider before bringing one into your home.

What is a home energy management system and how does it work

A home energy management system is a smart solution that helps you monitor and manage electricity use across your home. These systems use connected devices, sensors, and software to track energy consumption in real time, offering visibility into how, when, and where energy is being used. The goal is to give homeowners more control over their energy usage while reducing waste and improving overall efficiency.

In a smart home, a HEMS is a central hub that gathers data from appliances, lighting systems, HVAC units, and other energy-consuming devices. It uses this information to provide insights, send alerts, and in many cases, automatically adjust settings to reduce unnecessary energy consumption. Features like energy monitoring, scheduled automation, and usage reports help optimize performance and cut down on electricity costs.

HEMS are sometimes confused with building management systems (BMS), but they serve different purposes. A BMS typically manages larger commercial or industrial buildings and focuses on overall building operations like HVAC, lighting, and security. HEMS, by contrast, are designed for residential use, emphasizing energy tracking and household-level control within a smart home environment.
