You could look at StdCalculate, but weewx is quite comfortable getting a
UV index from a hardware weather station, and getting it via
MQTTSubscribe instead seems straightforward.
If you can have the ESP8266 emit json with both some radiometric UV
values and index in a dictionary, and then choose later, I'd do that.
