Connecting your Fastmail Calendar to TRMNL takes just a few seconds.

Inside TRMNL, navigate to Plugins > Fastmail Calendar.

Note: Enabling this plugin requires publishing your Fastmail calendar to an anonymized "ICS" style format. This is similar to publishing an unlisted YouTube video or "view with link" permission Google Docs file. If your calendar has sensitive data you may limit the published permissions to only expose timestamps, not event details.

Inside Fastmail, navigate to Settings > Calendar. Beside the calendar you wish to integrate with TRMNL, click the Edit & Share button.

In the Publish section and click the toggle button next to Full event details or Free/busy information, depending on what information you wish to share. (source)

Click "Copy to clipboard" below this long URL.

Back inside TRMNL, paste your published calendar link into the ICS input field. Important: replace the "webcal" text with "https" so your full URL looks like https://user.fm/calendar/v1-.....

Next you may set a few preferences.

Sync Recurring Events

This is a quirk of ICS style calendars in general -- when you make a recurring event, only 1 record exists. Since TRMNL only fetches recent events to generate your screens by default, we need to manually sync much older events that have recurring schedules in order for their future occurences to appear. After clicking to Save your new plugin, click the "Perform" link underneath this section and TRMNL will store old, recurring events. You only need to do this once.

Time Format

24 hours vs 12 hour (AM/PM) style.

Include Description

If "Yes," a truncated preview of the event's description field will be shown beneath the event title. Note that on the "default" Layout (explained below), setting this option to "No" will ~double the number of events shown thanks to saved space.

First Day of Week

Applies only to the "month" view. Tis allows you to set which day of the week is represented by the first column, furthest to the left. Defaults to Sunday.

Ignored Phrases

Supports a list of words that will be used to ignore events based on title or description content.

Layout

Note that only "Week" and "Month" layouts support multi-day events, but every layout supports all-day events.

Example - Week layout with multi-day event ("Michael OOO")

Example - Default layout with all-day event ("Michael OOO")

Example - Month layout with multi-day event:

Based on your device's refresh settings, you'll begin seeing Fastmail Calendar events very soon.

Note: while we fetch data according to your refresh interval, TRMNL only generates new screen renders if the data fetched contains changes. Thus setting your layout to "Default" (which shows 2-3 days) but updating an event 4+ days in the future will not trigger a screen refresh.

Stay focused.
