v1.0.13

🐛 Bug Fix

Negative Midnight Values

• Fixed negative cumulative sum values appearing at midnight
  • Issue: When importing today's data multiple times per hour, the integration was incorrectly starting from today's partial cumulative sum instead of yesterday's final sum
  • This caused midnight (first hour of new day) to show negative values like -513.96 gallons

✅ Testing

New Validation Test Added

• Added test_cumulative_sum_across_days to test_login.py
  • Validates cumulative sum calculations across day boundaries
  • Fetches yesterday's data and calculates final cumulative sum
  • Fetches today's data and verifies it starts from yesterday's final sum
  • Three validation checks:
    • ✅ First hour cumulative is positive (not negative)
    • ✅ First hour cumulative = yesterday final + first hour usage
    • ✅ Final cumulative = yesterday total + today total
