Bench sense is a script for detecting when a person is sitting on a chair and logging that data to Google Sheets. It requires a Raspberry Pi with a pressure sensor hooked up to it in a very specific manner.

To really use the script you first need to configure the Google Sheets access.

First install Poetry, which is used for managing the Python environment and dependencies.

Then install the dependencies

poetry install

Then start the script

poetry run start

Bench sense is now listening for pressure on the sensor, and will report sitting start and end times to the Google Sheet defined in bench_sense/config.py.

To run the script, you need API access to Google Drive and Google Sheets. Generate credentials to those and put the credentials JSON file that you got to the root of this folder with a file name of credentials.json.

Then you need to create a sheet and give access to that for the credentials you just created. Find the email from credentials.json and invite that email to edit the sheet from the normal sharing UI.
