Choose TRMNL Companion for calendars synced by the Companion app, or Apps Script for Google Calendar with accurate attendee response and out-of-office status. Use only one source per plugin instance.

Copy this private URL when setting up Google Apps Script or TRMNL Companion. Do not share it.

Setup: Copy this complete template into Code.gs at script.google.com. TRMNL displays copyable values on one line, but the script remains valid when pasted. In Project Settings, set the time zone to match your TRMNL account. In Services (+), add Calendar API. Copy the Calendar Webhook URL above into the PASTE_YOUR_CALENDAR_WEBHOOK_URL_HERE placeholder, review CONFIG, and keep visibleCalendarDays identical to the plugin setting below. Standard accounts should keep maxPayloadBytes at 1900; TRMNL+ subscribers may use 4900. Run pushNow() once and approve access; expect an HTTP 2xx line with calendar count, event count, byte count, and status totals. Then run installTrigger() once for five-minute updates.

Controls the clock, hour labels, and event times.

Alternate available-hour row fills. Disable to use the lighter fill for every available row; outside-hours shading and the current-hour fill are unchanged.

Any continuous range within Sun-Sat, for example Mon-Fri, Sun-Sat, or Tue-Sat. Apps Script users must enter the same value in CONFIG.visibleCalendarDays.
Example: Mon-Fri

Whole-hour display window in 24-hour time without AM or PM. For example, use 8-17 for 8 AM-5 PM.
Example: 8-17

Hours outside this range are striped. Use 24-hour time without AM or PM, either as one range such as 9-17 or per-day ranges such as Mon=9-17, Fri=8-16. Leave blank to disable.
Example: Mon=9-17, Tue=9-17, Wed=9-17, Thu=9-17, Fri=8-16

Comma-separated case-insensitive phrases to hide. Prefix a phrase with = to match the complete event name exactly.
Example: Focus Time, =Home

Remove emoji and leading symbols from event names. Disable to preserve them.

Enter comma-separated quoted strings to remove case-insensitively from event names. Quotes are required; commas inside quoted strings are kept as part of the text to remove.
Example: " - Weekly", ", Inc.", "Customer, External"

Choose whether timed event boxes show the full start–end range, the start time only, or no time.

Replace every displayed event title with Mock Event while preserving real event times, durations, response status, filtering, and layout.
