AirGradient ONE/ screen problem

[harald_haubner]

Concerning Indoor Air Quality Monitor AirGradient ONE/22.10.2025:

Since about two months I have at least twice a week a unreadable pixel salat on the screen. If I plug out and replug it comes back to normal. What is the problem, please?
Kind regards

Hi @harald_haubner! Welcome to the community!

The issue you’re describing usually happens when the device isn’t receiving stable power.

Could you please try using a 5V / 2A power adapter and ensure the USB cable is in good condition? This typically resolves the problem.
