Did anyone tried to use the official speedtest cli from https://www.speedtest.net/de/apps/cli
It seems like the speedtest-cli from Sivel is not made for speeds over 400 Mbit/s.
Atleast for me the speedtest-cli almost never reaches the full speed while a measuring from the same host with speedtest net works fine.
Edit: I was able to get the rule running with the official speedtest cli and will create a new thread.
Edit2: I created a new thread for the Speedtest CLI by Ookla measurement
