🎯 Description

Add practical automation examples to the documentation showing how to use the flow rate sensor for alerts.

💡 Hints

• Add to README.md under a new section or expand existing automation examples
• Look at existing automation examples around line 300-350 in README.md
• Consider examples like:
  • Alert when flow rate exceeds normal levels (possible leak/jam)
  • Alert when flow rate is unusually low
  • Tracking average flow rate over time

✅ Acceptance Criteria

• Add 2-3 practical flow rate automation examples
• Include clear descriptions of what each automation does
• Use proper YAML formatting
• Test that the examples are valid
