How content updates work

Static display mode

• Used for: Image, Text, QR Code.
• Content is sent once and displayed until changed.
• Wi-Fi can be disabled to conserve power.
• Display keeps the content even when powered off (that's eInk).
• Very low power consumption.

Update intervals

During a refresh

1. The screen may briefly flash black and white — this is normal for eInk.
2. New content appears within 1 – 2 seconds.
3. The device returns to low-power state until the next update.

Staying connected

• Stable Wi-Fi: keep your router on and working.
