Learn how to monitor your energy use at home with a Raspberry Pi, Grafana and Prometheus

Austin Freels shares his experience of using a Raspberry Pi, Grafana, and Prometheus to monitor home energy consumption, aiming to identify which household devices consume the most power. He utilized an Emporia Vue 2 energy monitor to gather energy metrics, which are then processed by HomeAssistant and Prometheus before being visualized on a Grafana Cloud dashboard. Freels outlines the step-by-step process, including configuring the Raspberry Pi with necessary software such as Prometheus and Docker, setting up Grafana Cloud for data visualization, and using HomeAssistant to manage energy data. He emphasizes the ease of use and potential cost savings, noting his discovery that his water heater accounts for a significant portion of his energy bill. Freels encourages others to try this setup and offers insights into the benefits of Grafana Cloud's free and paid plans for comprehensive monitoring solutions.
