Update Behavior

How Often Display Updates

Configured Interval (default: 5 minutes):

• Device wakes from sleep
• Connects to WiFi (2.4 GHz)
• Fetches latest data
• Updates display
• Returns to sleep

Why Not Continuous?:

• Saves battery life
• E-paper doesn't need constant refresh
• Information doesn't change that quickly
• 5-minute updates provide good balance

Display Refresh Process

1. Wake from Sleep (< 1 second)
2. Connect to WiFi (5-10 seconds)
3. Fetch Weather Data (2-5 seconds)
4. Fetch Departure Data (2-5 seconds)
5. Render Display (30-45 seconds)
   • E-paper refresh is slow (this is normal!)
   • You'll see the display flash/flicker
   • Final image appears after refresh
6. Enter Deep Sleep (until next update)

Total cycle time: ~40-70 seconds

E-Paper Characteristics

Normal Behavior:

• ✅ Display "flickers" during refresh (black/white flash)
• ✅ Takes 3-4 seconds to fully update
• ✅ Image persists without power
• ✅ Slight "ghosting" from previous image

Not Normal:

• ❌ Display stays blank
• ❌ Corrupted/garbled image
• ❌ Never refreshes
• ❌ Only partial update

See Troubleshooting if you experience issues.
