How to Use a Raspberry Pi Zero to Send Power Queen LiFePO4 24V 100Ah Battery Data to Home Assistant via MQTT

This guide walks you through setting up a Raspberry Pi Zero to monitor the Power Queen LiFePO4 24V 100Ah battery. Using Bluetooth, the Pi reads real-time data like voltage and state of charge, and then pushes updates to Home Assistant every three minutes via MQTT. This setup is ideal for battery monitoring automation, providing continuous, accessible insights directly from Home Assistant. By following these steps, you’ll have a reliable and efficient energy monitoring solution integrated into your smart home system.
