NOAA UV updates are giving lots of these errors

[lordwizzard]

As the title states, I getting lots of errors from the NOAA UV integration. I had 50 of these in a day. I can go to NOAA website and get the data, but this seems to be failing. Is the API at NOAA functioning?

Thanks for the report. I can't reproduce this issue, and the NOAA API appears to work for me. Can you try an few things to see if we can narrow down the issue:

• Did this used to work, or has this never worked for you?
• Can you look in the history for the sensor.uv_index entity to see if it has been failing 100% of the time or has some times succeeded?
• From the same network as your home-assistant server, does https://data.epa.gov/efservice/getEnvirofactsUVDAILY/CITY/Seattle/STATE/WA/JSON load correctly for you? If possible, does it work from the device your home-assistant is running on?
• Can you load https://ip6.me/ from the same network as your server and tell me whether the very top of the page says "You are connecting with an IPv4 Address" or IPv6.

It worked reliably for the last 2 years and now getting these errors, I use Detroit, Mi for my data.

* Can you look in the history for the `sensor.uv_index `entity to see if it has been failing 100% of the time or has some times succeeded?

Not sure on how to do that on a Home Assistant - Yellow

Looks like it is pulling Detroit MI like it should, so I don't understand why the report of issues with the integration

[lordwizzard]

I found "Browser" for Home Assistant which I have added to my Integration. I've set it to run the URL test string for Detroit MI. When I run it it returns a green check mark so I think that means it is good. So it must be so sort of logic error triggering the failed updated message. I say that because I got 3 errors when manually running that test string and got a green check mark.

Additional Information:

Installation method Home Assistant OS
Core 2025.12.2
Supervisor 2025.12.3
Operating System 16.3
Frontend 20251203.2

NOAA UV version 1.0.0

This is from HA Developer Tools > States

So there been no changes to the states for the last 2 plus hours, with it polling and returning these errors continuously. Polling is defaulted to what ever the integration has. It should be paused after sunset and before sunrise but continues throughout the 24 hours.

Hmm, not sure what would be causing this besides network or server-side issues. I will add retry logic to the integration which would make it more resilient to random errors, however given you are seeing this fairly consistently it might not fix it for you.

[lordwizzard]

You might stop polling 30 minutes after sunset and start again 30 minutes before sunrise. Just a thought
