I would like to upload the temperature and pressure data measured with Rasp Pai to a Google spreadsheet.

python google_spreadsheet.py
Logging sensor measurements to t, h every 30 seconds.
Press Ctrl-C to quit.
Temperature: 25.5 C
Humidity: 51.2%
Append error, logging in again

I refer to this site.

According to here, API is enabled and service account key is obtained.
The contents of the acquired account key are also described in the code.

# Google Spreadsheet DHT Sensor Data-logging Example
# Depends on the 'gspread' and 'oauth2client' package being installed.If you
# have pip installed execute:
# sudo pip install gspread oauth2client
# Also it's _very important_ on the Raspberry Pi to install the python-openssl
# package because the version of Python is a bit old and can fail with Google's
# new OAuth2 based authentication.Run the following command to install the
# the package:
# sudo apt-get update
# sudo apt-get install python-openssl

# Google Docs OAuth credential JSON file.Note that the process for authenticating

# in and authenticate with the gspread library.
# more complicated than the old process.You _must_ carefully follow the steps on
# this page to create a new OAuth service in your Google developer console:
# http://gspread.readthedocs.org/en/latest/oauth2.html
#
# Once you've followed the steps above you should have downloaded a .json file with

# Place that file in the same directory as this python script.#
# Now one last _very important_ step before updating the spreadsheet will work.
# Go to your spreadsheet in Google Spreadsheet and share it to the email address
# inside the 'client_email' setting in the SpreadsheetData-*. json file. For example
# if the client_email setting inside the .json file has an email address like:
# [email protected]account.com
# Then use the File->Share ... command in the spreadsheet to share it with read
# and write acess to the email address above.If i don't do this step then the
# updates to the sheet will fail!

It would be helpful if you could point out what was wrong.

  • Answer # 1

    I don't know the answer, so I think it's a direct solution. How about writing to GoogleSpreadSheet using IFTTT?

    I do this.
