rpi-speedtest

Network speedtest script to be run on Raspberry Pi

On Raspberry

Installation

Assumes you have API server deployed already.

• Connect to network (WiFi setup docs)
• Install NodeJS for correct ARM version (uname -m)
  • Select node version binary hat supports ARM version
• $ git clone $url/rpi-speedtest.git
• $ cd rpi-speedtest
• $ npm i
• Modify config file

Verify it works

$ node bin/index.js
91.40834570638205
ok 200

Setup CRON

• Open editor mode crontab -e
• Add something like 15 * * * * /usr/local/bin/node /home/pi/rpi-speedtest/bin/index.js to run the script every 15th minute. Safest way is to puth full path to node installation.

Caveats

• I was testing on Raspbian which has cron logs disabled by default, make your call, for me it is not necessary.
• I did have node and npm preinstalled on Raspbian, make sure you have those installed and available in PATH.
