☕ If you enjoy my tutorials, I'd be so grateful if you could Buy Me A Coffee! https://buymeacoffee.com/janpiapiae

In this video, I demonstrate step-by-step how to improve the stability of Modbus data readings from an energy meter in Home Assistant using ESP32. I show how to configure the ESPHome integration, monitor the accuracy of readings, and perform long-term testing ⏳. After several hours of testing, we compare the results to see if previous issues with value anomalies have been resolved 📊. Finally, I plan to revert to the old configuration to double-check the results and ensure everything is working as expected 🔄.
