Ideas for Sensors

• Weather station (Temperature, Humidity, Air Pressure)
• Water temperature (lake, garden pond)
• Water level (cistern, garden pond, river)
• PIR sensor for movement (garage, selfstorage, ...)
  • Also Door openings
• Offgrid solar monitoring
• Postbox status -> "You got mail!"
• Garden/Plant monitoring
• NOx
