Data Storage

MedMate stores all data locally in Home Assistant's storage directory:

  • Location: config/.storage/medmate_medicines
  • Format: JSON
  • Includes: Medicine details, schedules, prescriptions, inventory, and dose history

Troubleshooting

Medicine Not Showing Up

  1. Check that all files are in the correct directory
  2. Restart Home Assistant completely
  3. Check the logs for any error messages

Entities Not Updating

  1. Check if the coordinator is running properly
  2. Look for errors in Settings > System > Logs
  3. Try reloading the integration

Config Flow Issues

  1. Make sure medicine names are unique
  2. Check that all required fields are filled
  3. Verify dates are in the correct format

Advanced Usage

Custom Time Slots

While the integration includes preset times (morning, lunchtime, dinner, night), you can extend the DEFAULT_TIMES dictionary in coordinator.py to add custom times:

DEFAULT_TIMES = {
    "morning": time(8, 0),
    "lunchtime": time(12, 0),
    "dinner": time(18, 0),
    "night": time(22, 0),
    "bedtime": time(23, 30),  # Custom time
}

Multiple Medicines

You can add multiple medicines by running the integration setup multiple times. Each medicine gets its own device and set of entities.

Data Export

Since data is stored in JSON format, you can easily backup or export your medicine data from the storage file.

Contributing

This integration can be extended with additional features:

  • Medication interaction checking
  • Dose tracking analytics
  • Integration with health apps
  • Barcode scanning for medicine identification
  • Advanced scheduling (every other day, etc.)

Support

For issues, questions, or feature requests, please check:

  1. Home Assistant logs for error messages
  2. Ensure all files are properly installed
  3. Verify your Home Assistant version compatibility

Note: This integration is for tracking purposes only and should not replace professional medical advice. Always consult with healthcare providers for medical decisions.
