Home Energy Reporter is a tool designed to help you better understand and optimize your energy consumption patterns using data from your Home Assistant setup. By analyzing your energy usage across different times of the day and days of the week, the tool identifies opportunities for savings based on predefined energy plans. It provides insights into your consumption behavior, helping you make informed decisions to reduce costs and improve energy efficiency.
- Connects to Home Assistant: Uses WebSocket API to authenticate and retrieve energy consumption data.
- Customizable Energy Plans: Allows defining multiple energy plans with specific discount rates based on hours and days.
- Time Period Selection: Generates reports for a specific month and year or for the current month by default.
- Cost Calculation: Calculates the total energy cost before and after applying the best discount from the available energy plans.

Make sure you have Python 3.10+ installed. Then, install the required Python libraries:
pip install websockets python-dotenvYou can now run the tool to generate a report. The report can be run for the current month or for a specific month and year:
-
To generate a report for the current month:
python energy_report.py
-
To generate a report for a specific month and year:
python energy_report.py --month 7 --year 2023
The tool will output a detailed report in your terminal, including:
- Hourly energy consumption as an ASCII bar chart.
- Total energy consumption (in kWh).
- Discount calculations for each defined energy plan.
- Best discount applied and the total cost after the discount in descending order.
- At the beginning it displays 3 best discounts.
