PyEmChargeOnSolar

Overview

This project integrates solar/battery and Emporia systems to automate the charging of electric vehicles. It aims to optimize energy usage by leveraging solar power and managing grid consumption efficiently. Thanks to magico13/PyEmVue for the Emporia API integration and itayke/solaredge-emporia-autocharge for the idea and basis for the script.

Features

• Automated EV charging based on solar production
• Real-time monitoring of energy consumption
• Customizable charging schedules
• Integration with SolarEdge, Tesla Powerwall (via pyPowerwall Proxy) and Emporia APIs
