Backlight

The panel automatically adjusts screen brightness based on time of day — brighter during daylight, dimmer at night.

How it works

Sunrise and sunset times are calculated on-device from your selected timezone using a NOAA solar algorithm. During the day, the panel uses your daytime brightness; at night, it switches to nighttime brightness. The transition is checked every 60 seconds, and sunrise/sunset are recalculated at midnight. No internet connection or Home Assistant is required.

Settings

Configured in the Brightness section of the Settings tab in Setup.

• Daytime brightness — screen brightness during the day (10%–100%, default 100%).
• Nighttime brightness — screen brightness at night (10%–100%, default 75%).

Sunrise and sunset times are derived from the timezone set in the Clock settings.

Screensaver

When the screensaver is active, the backlight turns off. On wake (touch or presence sensor), brightness returns to the correct level for the current time.

Before clock sync

If the panel hasn't synced its clock yet, it defaults to daytime brightness. Once synced, sunrise and sunset are calculated immediately.
