  Setup

  This guide assumes your Raspberry Pi has been configured and is already connected to the Internet. If not configured you can quickly do so using this quick start guide from the Raspberry Pi Foundation.

  NOTE: If you’re using a WiFi dongle, we suggest using Wicd to manage your WiFi connection.

  Connecting the NanoPi to Ubidots using Python

  With your Raspberry Pi connected to the Internet, verify the IP address assigned to the board access using ssh in your computers terminal:

  ssh pi@{IP_Address_assigned}
  

  • User Name: pi

  • Password: raspberry

  As you can see the image below, your access was successful, and the user now is pi@raspberrypi:

  
  Now let's upgrade some packages and install pip, Python's packet manager:

  sudo apt-get update
  sudo apt-get upgrade
  sudo apt-get install python-pip python-dev build-essential 
  

  Install the below libraries:

  • requests: to make HTTP requests from Python to Ubidots

  • pyspeedtest: to measure the Internet speed from Python

  pip install requests pyspeedtest
  

  Pro Tip: FAQs and Troubleshooting - If you get a permission issue when installing the packages required, change the user mode to root using the following command: 

  sudo su

  Now it is time to code!

  Create a Python script in your computer's terminal:

  nano ubi_speed_tester.py 
  

  And copy this code into it:

  #!/usr/bin/python
  import pyspeedtest
  import requests
  st = pyspeedtest.SpeedTest()
  payload = {'Download': round(st.download()/1000000,2) , 'Upload': round(st.upload()/1000000, 2), 'Ping': round(st.ping(),2)}
  r = requests.post('http://things.ubidots.com/api/v1.6/devices/raspberry-pi/?token=YOUR-UBIDOTS-TOKEN-HERE', data=payload)
  

  Make sure to replace your Ubidots account token in the request URL. If you don't know how to get your Ubidots Token, please see the article below:

  • Find your TOKEN from your Ubidots account

  Now let's test the script:

  python ubi_speed_tester.py
  

  If working properly you will see a new device in your Ubidots account with three variables: Download, Upload, and Ping:
