Grafana dashboard: Home Energy Usage v2
Description: A dashboard that shows your home energy usage. Using Prometheus, Home Assistant and the Emporia Vue 2.

This grafana dashboard is using HomeAssistant to connect to my energy monitor ( Emporia Vue 2). We are then natively exposing metrics in prometheus format from HomeAssistant and scraping those with a Prometheus server/Grafana Agent.
