Running the AirGradient ONE in Offline Mode

Offline mode allows the AirGradient ONE to operate without connecting to Wi-Fi. Sensor readings remain active and visible on the display. No data is sent to the AirGradient dashboard while running in offline mode.

How to enable Offline Mode

1. Locate the BOOT button

On the back of the monitor, next to the USB connector, there is a small hole.
Inside is the BOOT button that can be pressed using a small screwdriver or pin.

2. Power on / power cycle the monitor if it was already on.
   

3. Wait for the prompt
   During startup, the display will show the message: “Press now for offline mode”

4. Press the BOOT button

Press the BOOT button through the hole while this message is shown.

4. Confirm Offline Mode

If successful, the display will show: “Offline mode = true”

The monitor will now run fully offline. The display will have an airplane mode icon:

Switching back to Online Mode

To return the monitor to normal (online) operation:

• Repeat the same steps above
  
  

• When prompted, press the button again during startup

The display will confirm that offline mode is disabled with the message: “Offline mode = false” and the airplane icon will disappear.
