Stable UV Index site for US

[bodylinksystems]

I used to get my UV index from a site that is paid now. I can't seem to extract it via openweather, nor can I get it from the EPA (UV Index Search | US EPA)-- since they use a .gif for the number (I would need to extract the ALT= text.) I'm looking to get the MAX UV level for that day, not necessarily the current as they usually offer the max UV number.

example EPA result:

I have tried JSON, text, html selectors and the scraper tool. no joy. Have I forgotten how to node-red from one summer to the next?

My weather station worked fine last year, but the UV change has me scrambling a bit. Any tips are greatly appreciated. It's just my own personal little weather station based on an 8266, and a Pi3B+ running NR and MQTT -- and I'm using the UV to plan skin safety during the summer.

It seems alot of the pages I used to scrape are now generated on the fly so a new tactic must be used...

They also have an open api available it seems

@bodylinksystems This looks something many could benefit from. Do you have plans to share your flow?

@zenofmud @bakman2 this is working for me right now. Hope it helps someone else
