I’m trialing a 4G home broadband router at the minute to see if it can give me decent upload as apposed to the 1mbps I currently get so I thought I’d look into automatically running speedtests. Here’s how and it turned out to be quite simple. Caveat, this runs on Linux.
If you don’t have pip or python installed run this: “sudo apt install python-pip”
This will install pip and the prerequisites, one of which is Python itself. Next up, in your home directory, run “speedtest-cli –csv-header >> speedtest.csv”. This will create an empty CSV with only the headers in it.
Next up, and finally, run “crontab -e” and enter “*/10 * * * * /usr/local/bin/speedtest-cli –csv >> ~/speedtest.csv”. Thanks to this thread for giving me the answer as to why it wasn’t working to start with.
That’s it! Every 10 minutes a speedtest will be run and the results appended to the csv file. Load it up in a spreadsheet program and job done.
It isn’t a long term solution as that csv will get unweildy after a while but this is a two week trial so not an issue. I’ve an aging Raspberry Pi B hooked up to the router and will check the results in a day or so to see what the connection is like without anything else on it.
