Go's HTTP interface doesn't serve anything

Support
#1

Hi, I got my Go a week ago and I can’t seem to get the HTTP endpoint to serve me anything. I’ve got it set to ‘Stationary’, the display reports the IP. I’ve toggled it back and forth between portable/stationary, turned it off an on. But the server just returns a 404 on any endpoint I try, like:

% curl -i http://192.168.30.99/
HTTP/1.1 404 Not Found
Content-Type: text/html
Content-Length: 29

Nothing matches the given URI

My config endpoint is http://hw.airgradient.com/sensors/airgradient:10bda3e48370/go/config

Am I missing something?

Hi @tall.lock, welcome to our community!

Could you try these endpoints instead?

For measurement:

curl -i http://192.168.30.99/api/v1/measures

For configuration:

curl -i http://192.168.30.99/api/v1/config

Alternatively, you can use the .local URL (please replace the SERIALNUMBER with your AirGradient Go’s serial number)

http://airgradient_SERIALNUMBER.local/api/v1/measures

http://airgradient_SERIALNUMBER.local/api/v1/config

You can take a look at this document for more information about the local HTTP API: firmware-core/docs/local_http_api.md at main · Open-Air-Foundation/firmware-core · GitHub

Please let me know if you still experience any issues or have any questions. Thanks!

Ah, that works. I was looking at old docs (and also had Home Assistant 2026.8, which was also too old).

Thanks!

Hi @tall.lock, glad to hear that it works!

I hope you enjoy using your AirGradient Go with your local setup and Home Assistant.

Please feel free to let us know if you experience any issues.

For those who have the same question, the information below could be helpful.

The local API URLs for AirGradient Go are different from those for AirGradient ONE and Open Air.
