You’ll see the current firmware version there.

Option 2: Using the Local API (Advanced)

If your monitor is connected to your local network, you can also check the firmware version through the monitor’s built-in local API.

Use this address in your browser:

http://YOUR_SERIAL_NUMBER.local/measures/current

Replace the serial number with your own monitor’s serial number.

Example:

http://airgradient_ecda3b1eaaaf.local/measures/current

You’ll receive a JSON response like this:
