Average wind speed difference in WD vs MT (Meteotemplate)

I’m uploading data from WD to MT via API in every 10 seconds. Wind gust is consistent in both systems, however average wind speed differs a lot. What might cause this? Picture shows it well.

Problem solved. In WD graphs I had 10 minute average but maximum average value was not based on 10 min. Ticked that in setup - all ok.
