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. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
