Thank you! You're awesome! I used to use speedtest-cli to monitor my Internet speed regularly, in fact every 5 minutes, while also logging DOCSIS signal levels, when debugging connection issues. It didn't give accurate results, and that caused problems for me. I wanted to switch to the C++ version, but needed the JSON output to be able to log the data and analyze it.
