Smart Scheduling: Home Assistant and Google Calendar

Integrating Google Calendar with Home Assistant allows you to trigger automations based on your schedule. Imagine your lights turning on automatically 30 minutes before your first meeting, or your thermostat adjusting to the perfect temperature before you even wake up!

Setup Steps:

1. Enable the Google Calendar API: Go to the Google Cloud Console, create a project (if you don't have one), and enable the Google Calendar API.
2. Create Credentials: Create OAuth 2.0 credentials. Download the JSON file. Rename this file to !$0$!.
3. Configuration in Home Assistant: Place !$1$! in your Home Assistant config directory. Add the following to your !$2$!:

!$3$!

4. Restart Home Assistant. You'll be prompted to authenticate with Google in your Home Assistant logs. Follow the link to authorize.

Device Integration Tips:

• Event-Based Triggers: Use the !$4$! trigger in your automations. This trigger fires when an event starts or ends.
• Conditionals: Use conditions to ensure automations only run during specific times or days.
• Template Sensors: Create template sensors to extract information from your calendar events, such as the event location or description.

Best Practices for Reliability:

• Static IP Address: Ensure your Home Assistant instance has a static IP address.
• Automated Backups: Regularly back up your Home Assistant configuration.
• Log Monitoring: Monitor your Home Assistant logs for errors.
• Consider using secrets.yaml: Store the credentials for Google Calendar API separately in secrets.yaml file.

By integrating Google Calendar, you can build a truly smart and automated home, tailored to your schedule and needs.
