Building out a NodeRed dashboard for station control and want to add weather data, particularly lightening strikes. I’ve got the REST API working just fine but I noticed that several fields in the JSON metric when they should be imperial. Example, the air temperature is F, but the JSON value is C. Is this a bug?

Just re-read the REST docs and see “the station\_units values represent the units of the Station’s owner, _not the units of the observation values in the API response_.”

Problem solved.  
Thanks
