AirGradient PCB 3.0 not working with AirGradient Integration

Hardware
1

I have the older AirGradient PCB 3.0 that I’m trying to get to work Natively with Home Assistant through the Air Gradient Integration.
I followed the flashing instructions here:

Direct flashed through the browser and connected its wifi to my local network (same one that Home Assistant it on).
The AirGradient is running. I can see the sensor results on my screen and I can ping its IP address from Home Assistant. But when I put that IP address in the AirGradient Integration setup screen, it just responses with:

“Failed To Connect”

It’s not auto detected by Home Assistant either.

Ideas?

Thanks!

Any clues on the debug error logs?

There does not appear to be any debug error logs as AirGradient won’t install without connecting to its device first.

There is nothing in the Core logs or any other system logs.

I did note that the version installed from the AirGradient web site (listed in the OP) was dated 2023-08-21, if that helps any.

Thanks

I think I was led down the Rabbit Black-Hole by Google’s Artifical Ingorance engine. When I read this, I thought it would work. But further digging around on AirGadient forums lead me to believe it’s not longer supported:

AI Overview

Yes, the AirGradient PCB 3.0 works natively with Home Assistant

due to its recent “Works with Home Assistant” certification and native support in the latest firmware. Devices can be automatically discovered on the network, and once added, they will integrate seamlessly with the Home Assistant dashboard.

How it works

  • Native support: AirGradient’s firmware includes native Home Assistant support, which allows devices to be auto-discovered on your local network.
  • Seamless integration: Once discovered, the AirGradient monitor can be added to Home Assistant just like any other device, enabling you to see and use its sensors (like CO2, PM2.5, and more) directly in your dashboard and automations.
  • Local control: This integration relies on a local server, so it does not require a cloud connection for the device to send data to Home Assistant.
  • Ease of use: The setup is simple; you just need to connect the device to WiFi, and Home Assistant will find it automatically, eliminating the need for manual IP configuration or complex setups.

Here’s the AirGradient Forum link:

And the fact that the firmware is over 2 years old - and before “Work With Home Assistant” ‘certification’.

Ugh
