@rccoleman The Feels like Temperature in the REST API from WeatherFlow uses the formula you can find here: Derived Feels Like. Basically if the Temperature is below 10°C (50°F) it uses Wind Chill and above 26°C (80°F) it uses Heat Index. How exactly WeeWX does that calculation I have not looked in to.
I have a ‘sort off’ of working model that uses the UDP interface instead of the REST API. Obviously this will require people to have their own Weather Station, and thus this Component would be for a smaller audience - but as you write it has some advantages in reporting, due to Rapid Wind and not Cloud Based.
I have a ‘working component’ using the UDP interface, but currently it only catches Rapid Wind and Hub Status, as the UDP Listner needs to run in a Continues Loop in the background to make sure we catch all data. And my skills are not sufficient to create that - but if anyone has ideas on how to have a background process that can push data in to HASS, I would love to have an example.
@efleming Really glad it works, and thanks for helping testing it. No I have not posted it in the WeatherFlow forum yet, I wanted to make sure we had something working first. But I will do.
