Control the LEDs and Display on the AirGradient ONE

This guide walks you through all the LED and display settings available on your AirGradient ONE, so you can tailor it to your environment and preferences.

1) Enable Advanced Configuration Settings

Before anything else, you need to unlock the LED & Display controls.

• Go to General Settings

• Scroll down

• Enable Show Advanced Configuration Settings
• Click Save

Once enabled, a new “LED & Display” tab will appear in General Settings.

2) Open the LED & Display Tab

Here’s what you’ll see:

LED Mode

This controls what parameter the LED strip represents. Or turn it off completely.

• LEDs off
• LEDs on CO2 levels: Best for ventilation awareness
• LEDs on PM2.5 levels: Better if you care about particulates

Pick one based on what matters more to you. You can’t show both at the same time as there's only one LED strip.

CO₂ Configuration

This only applies if LEDs are set to CO2 mode.

You define when the LED color changes:

• Green → Amber (slightly elevated CO2)
• Amber → Red (high CO2)
  

Default Values:

• LED turns Amber at 1000 ppm
• LED turns Red at 2000 ppm

You can also set the level where all LEDs turn red.

Day & Night Time

This sets when the device switches between “day mode” and “night mode”.

Default Values

• Day Start - 08:00
• Day End - 20:00

These times control how brightness behaves in the next settings.

LED Brightness

You can set different brightness levels for:

• Day Time (as set in Day & Night Time above)
• Night Time (as set in Day & Night Time above)

 Typical setup:

• Day: brighter (visible across the room)
• Night: dim or almost off (avoid disturbance)

Display Brightness

Same idea as LEDs, but for the screen.

• Set brightness for day
• Set brightness for night

Auto Screen Off (2am–3am)

This settings helps extend display lifespan.

Notes

• These features require firmware version 3.1.1 or higher
• You can click “Apply to All Locations” if you manage multiple devices
• Changes will apply with 1-5 minutes after saving.
