Google Calendar

This driver allows for the use of Google Calendar as a scheduler.

HSYCO Configuration

Add a GOOGLECAL I/O Server in the I/O Servers section of the Settings and set its parameters:

High Availability

• Shutdown when inactive: defaults to false.

Options

ID	Default	Values	Description
pollinterval	10	n > 0	the data acquisition interval, in seconds
calendars		<id_list>	list of calendars IDs separated by ';' (see Setup for details). Omit this option to use the primary calendar
code		<code>	authorization code (see Setup for details)

Setup

Enable the Google Calendar API

• Use this wizard to create or select a project in the Google Developers Console and automatically enable the API. Click the Go to credentials button to continue.
• At the top of the page, select the OAuth consent screen tab. Select an Email address, enter a Product name if not already set, and click the Save button.
• Back on the Credentials tab, click the Add credentials button and select OAuth 2.0 client ID.
• Select the application type Other and click the Create button.
• Click OK to dismiss the resulting dialog.
• Click the Download JSON button to the right of the client ID.
• Move the downloaded file to HSYCO server, place it into a folder called "google-calendar" in the root and rename it "client_secret.json".

The "client_secret.json" can be reused for multiple I/O server instances, even on different HSYCO servers.

Create the calendar

• Go to [1] and create a Google account or use your personal one to login.
• If you are going to use the primary calendar for this account you are done, go to the next section. If, on the other hand, you want to create a separate calendar for HSYCO (or more that one), continue here.
• From the left column, click on the small option menu button on the right of My Calendars; select Create new calendar.
• Enter a name, set the other settings as desired and click on Create calendar.
• Find the created calendar from the list under My Calendars, select the option menu button on its right and select Calendar settings.
• Go to the section Calendar Address and copy the displayed Calendar ID.
• Go to the settings of the I/O Server and set the value of the "calendars" option to the copied calendar ID. If you want to use more that one calendar, repeat the above procedure to create another one and add its ID to the "calendars" option using ';' to separate the IDs.

Authorize access

The first time the driver is started it is required to grant it access to the calendar information of the selected Google account. This procedure is necessary for each I/O Server instance created.

Shortly after the driver is started for the first time, the value of the datapoint "auth" will be set to a long URL string. Copy that URL and paste it into a browser. Login with the selected Google account and click on Accept.

The next page will show a code. Go to the settings of the I/O Server and set the value of the "code" option to this code; save and wait for the server to restart.

Datapoints
