This project uses an ESP32 with a round display (ESP32-C3, model esp32-2424s012) to show real-time household power consumption (in Watts) and solar panel production, with data retrieved from Home Assistant. To make the interface more engaging, animated robot eyes are displayed in the center; their random blinking brings the application to life. The ESP32 is wall-mounted, allowing anyone to check energy consumption and production at a glance. The final result can be seen in the "Final Result" section below.
This code is part of an ESPHome project for energy monitoring.
To generate a random 32-byte API encryption key in base64 for ESPHome, run this command in your terminal:
openssl rand -base64 32Copy the output and use it as the value for api.encryption.key in your YAML file.
To launch the project, use the following command:
esphome run energyMonitorESPHOME-esp32-2424s012.yamlThis command compiles the energyMonitorESPHOME-esp32-2424s012.yaml configuration and uploads it to your ESP32 device.
This project aims to visualize household energy consumption and solar energy production using two gauges. The interface is designed to be user-friendly and engaging, featuring animated robot eyes that express emotions based on energy usage:
- High consumption: The robot appears upset.
- Low or negative consumption: The robot looks extremely happy.
This visual feedback helps users quickly understand their energy usage patterns and encourages efficient energy consumption.
Below is a mockup of the application's interface:
