GCal-Search

Now with choice of virtual contact or virtual presence devices

Steps to set this up...

1. Create a Google Project - https://console.developers.google.com and enable OAuth2 - see https://support.google.com/googleapi/answer/6158849

    a) Give your project any name (perhaps "HE-GCal")
    b) Enable the Calendar API - https://console.developers.google.com/apis/library
    c) Set up the OAuth Consent screen - https://console.developers.google.com/apis/credentials/consent 
          i) Application Type: Internal
          ii) Give it any name (perhaps "HE-GCal")
          iii) Add scope `../auth/calendar.events.readonly` (if you don't see it in the list, go back to step 1b)
    d) Create credentials - https://console.developers.google.com/apis/credentials
          i) Type: OAuth Client ID
          ii) Application Type: Other
          iii) Give it any name (perhaps "HE-GCal")
                           
    e) Copy the Client ID and Client Secret from the Google credentials you just made.  Paste them in a text editor, as you will need these later
   

2. Copy the code for the 2 Apps "GCal Search" and "GCal Search Trigger" into Hubitat, under Apps Code

3. Copy the code for the "GCal Switch" Driver into Hubitat, under Drivers Code

4. In Hubitat, go to the Apps page and install the "GCal Search" app. -This will walk you through connecting to Google and selecting a calendar and search terms. - You can create multiple connections, and based on your selection of virtual device, the app will create a virtual Contact Sensor or a virtual Presence Sensor that are Open/Present when the event starts and Close/Not Present when the event ends.
