Meetin

Loads events from your calendar and draw a countdown on LEDs.

Setup

1. Google Cloud OAuth client id

Create credentials.json to be able to fetch events from Google Calendar. Follow https://developers.google.com/workspace/guides/create-credentials to create a OAuth client ID file. Rename the file named similar to code_secret_client_<LONGSTRING>.apps.googleusercontent.com.json as credentials.json in the current directory.

• Create (or reuse) a Google Cloud project: https://console.cloud.google.com/
• Create OAuth consent: https://console.cloud.google.com/apis/credentials/consent
• Create OAuth client ID: https://console.cloud.google.com/apis/credentials
• Enable Calendar API: https://console.cloud.google.com/apis/library/calendar-json.googleapis.com

2.Home Assistant api key

Create api.key with a Long-Lived Access Token to access Home Assistant. You can create one from the Web UI by visiting http://IP_ADDRESS:8123/profile

3. Esphome

Flash a esp8266 or esp32 with esphome.io with a light configuration similar to what meetin.yaml defines.
