Bash - Speedtest.net Download/Upload/Ping monitoring

Purpose

This script uses the Python module speedtest-cli for testing internet bandwidth (Download/Upload/Ping) via speedtest.net.

It is not my script and I do not claim ownership of it (Source: Sander Filius: https://www.safiweb.nl/?p=1133).

This script will create 4 Virtual Sensors to monitor internet bandwidth and uptime:

• Download (Graph)
• Upload (Graph)
• Ping (Graph)
• Broadband (Switch to manually trigger Bash script)

Dependencies - hardware / software / operating system

• Python 2.4-3.5 at time of writing
• speedtest-cli Python module (https://github.com/sivel/speedtest-cli)

Steps

• Open a SSH session and install speedtest-cli using
  sudo apt-get install speedtest-cli
• Within Domoticz open the Setup > Hardware screen
• Create 3 Virtual Sensors with the "Custom" Type named:
  • Download
  • Upload
  • Ping
• Create 1 Virtual Sensors with the "Switch" Type named:
  • Broadband
• Within Domoticz open the Setup > Devices screen and note the IDX of each new Virtual Sensor added, you'll need this in the Bash script
• Create a new file within /domoticz/scripts/ called speedtest.sh
• Change the permissions on speedtest.sh to allow it to run from crontab
• Edit the speedtest.sh file
• Copy and paste the contents of the Bash script section below
• Change the following fields:
  • host (to match your IP address or localhost)
  • idxdl (the IDX of the Download device)
  • idxul (the IDX of the Upload device)
  • idxpng (the IDX of the Ping device)
  • idxbb (the IDX of the Broadband device)
• Save changes and run the Bash script, if successful after a moment it will display your Download, Upload and Ping
• Within Domoticz open the Setup > Log to confirm that Domoticz was informed of this data
• Within Domoticz open the Utility tab and check that data is being recorded
• Within Domoticz open the Switches tab
• Click Edit within the Broadband device
• Set the On action to "script:///home/pi/domoticz/scripts/speedtest.sh" (replace pi with your user and/or correct absolute path)
• For automatic reporting you could add a crontab task to run the Bash script speedtest.sh at given intervals (e.g. every 24 hours, etc.)
