Office Status Indicator

Summary

This is a project to create a Google Calendar integrated status indicator for home office use.

This project utilizes the following hardware:

• Raspberry Pi Zero W
• Unicorn HAT Mini

Requirements

• Docker installed on your Raspberry Pi
• A Google Project with the Calendar API enabled

Setup

First, you'll need to create a Google Calendar API project. There's a good tutorial here. Download the credentials.json file for the project - you'll need it to allow the project to access your Google calendar - and then either copy the file to your container and place it in the /app directory, or mount the file to the container from the host.

On the Raspberry Pi Zero W with the Unicorn HAT Mini, run the following command to download and run the container:

docker run -it \
           --name office-status \
           --privileged \
           --restart=always \
           --volume $(pwd)/:/app/data \
           --volume $(pwd)/credentials.json:/app/data/credentials.json:ro \
           alannix/office-status:latest

This will prompt you to visit a URL to authorize the script to have access to your Google Calendar. Once you have gone through the authorization process, you'll receive an authorization code that you'll need to provide back to the application. The authorization code is stored within the container, so you can safely exit (Control + c) and the container will restart and continue to run.

Once the application is authorized, it will check your Google Calendar for events every minute, determine if you're in a meeting, then update the state of the status light accordingly.

Configuration

You can tweak the operation of the script by providing any of the following environment variables:

Name	Description	Type	Default
OFFICE_STATUS_HOUR_START	The hour of the day that the status light should activate.	Integer	8
OFFICE_STATUS_HOUR_END	The hour of the day that the status light should de-activate.	Integer	18
OFFICE_STATUS_TZ	The timezone that should be used to determine working hours.	String	"America/New_York"
OFFICE_STATUS_WARNING_MINUTES	The number of minutes prior to the next meeting that the light should change to 'warning' status.	Integer	10
OFFICE_STATUS_WEEK_START	The integer representation of the day of the week to start the work week (Monday is 0 and Sunday is 6)	Integer	0
OFFICE_STATUS_WEEK_END	The integer representation of the day of the week to end the work week (Monday is 0 and Sunday is 6)	Integer	4
