1.1 Workflow description

Title: Send preventive maintenance schedules with Google Sheets and Gmail ICS invites
Workflow name: Send preventive maintenance schedules with Google Sheets and Gmail ICS invites

🗓 Preventive Maintenance Scheduler via ICS Email (n8n | Google Sheets | Gmail)

This workflow automatically reads your daily preventive maintenance schedule from Google Sheets and sends each assigned team member a personalized calendar invite (.ICS) as an email attachment. No more manual reminders or copying events — your operations and field teams will always be on schedule with clear, actionable reminders!

Who’s it For

Maintenance teams at plants, renewable sites, factories.
Facility and operations managers.
Any field crew, service team or org using Google Sheets and email for coordination.
Businesses wanting reliable, zero-touch preventive maintenance notifications.

How it Works

Daily Trigger: Workflow runs automatically every morning at 7:00 AM.
Read Maintenance Tasks: Pulls all scheduled maintenance for today from Google Sheets.
Generate ICS Data: Prepares universal calendar event details: summary, location, time, assignee, etc.
Create ICS File: Converts event data into a standard .ics calendar invite file with correct timings and description.
Send Calendar Invite Email: Sends a personalized email to each assignee, with the .ics file attached — ready to add to Outlook, Gmail or mobile calendar.

How to Set Up

Import the workflow JSON into your n8n instance.
Set up connections in n8n:

Authenticate Google Sheets (read access) and Gmail (send access).

Format your Google Sheet with headers: date, asset, task, location, email
Activate the workflow. It runs daily on schedule. You can test it manually for validation.
Each day: Team members with tasks scheduled for that date are sent their personalized event invite.

Requirements

Tool	Purpose
n8n Instance	Run and schedule the automation
Google Sheets	Source of maintenance schedule/tasks
Gmail (or SMTP)	Email platform to send calendar files

How to Customize

Use Case Examples

Wind turbine engineers receive daily calendar invites for inspections.
Solar O&M operators are automatically reminded for inverter cleaning via calendar sync.
Facility staff gets scheduled reminders for HVAC or safety checks without manual admin.
Managers have a clear audit trail of which reminders were sent on time.

Common Troubleshooting

Issue	Possible Cause	Solution
No email received	Gmail/SMTP misconfigured	Check node credentials, token or SMTP settings
Calendar file comes as .txt	Wrong file type/extension/MIME	Ensure "Create ICS File" outputs `.ics` and `text/calendar`
No invites sent for today	No matching rows in Google Sheet	Check date/value format; add sample data for today
Google Sheets returns error	Wrong Sheet ID/tab, access issue	Confirm correct Google Sheet is linked and shared
Event time/zone is incorrect	Code node’s time logic not matching	Adjust start/end time settings in the code node

Tag stale ClickUp tasks and escalate overdue items with assignee comments

## Quick overview This workflow runs daily on a schedule and checks ClickUp tasks in one or more lists for inactivity based on the task’s date_updated field, automatically applying “stale” tags and escalating long-idle tasks by tagging them and posting an assignee comment. ## How it works 1. Runs every day at the configured hour using the schedule trigger. 2. Loads monitoring settings (statuses, tags, stale thresholds, and tag names) and fetches matching tasks from the selected ClickUp list(s), then merges and deduplicates them. 3. Skips tasks that already have the second-level stale tag (for example, stale:14). 4. For tasks without the first-level stale tag, checks the last updated timestamp and adds either the first-level stale tag (for example, stale:7) or the second-level stale tag if they already exceed the higher threshold. 5. For tasks that already have the first-level stale tag, checks whether enough time has passed since that tag was applied and, if so, removes the first-level tag and adds the second-level stale tag. 6. When a task is escalated to the second-level stale tag, posts a warning comment on the ClickUp task and assigns the comment to the task assignee (or the creator if no assignee exists). ## Setup 1. Add a ClickUp API credential (OAuth or API token) and select it on all ClickUp nodes. 2. In the ClickUp task search node(s), choose the list(s) you want to monitor and enable/configure the second list node if you want to pull tasks from multiple lists. 3. Update the monitoring settings (monitoredStatuses, monitoredTags, daysUntilFirstStaleTag, daysUntilSecondStaleTag, and the stale tag names) to match your ClickUp workspace conventions. 4. Adjust the schedule trigger time and, if needed, set the workflow timezone in n8n settings so the run time matches your local time. ## Requirements - A ClickUp account with API access - ClickUp credential configured in n8n - At least one ClickUp list to monitor ## Customization - Change thresholds — Edit `daysUntilFirstStaleTag` and `daysUntilSecondStaleTag` in `SetContext` to any number of days - Change tag names — Update `firstStaleTagName` / `secondStaleTagName` to match your ClickUp tag naming convention - Monitor different statuses — Edit `monitoredStatuses` and `monitoredTags` in `SetContext` (e.g. add `review`, `blocked`) - Add more lists — Duplicate `GetTaskFromList1`, update the List ID, enable the node, and connect its output to a new input port on `AppendListTasks` - Change schedule — Open `TriggerRegularly` and switch from daily to weekdays-only or any custom cron interval - Disable subtasks — Open each `GetTaskFromList` node and set `subtasks` to `false` in the Filters section

Summarize daily Slack standups with OpenAI, Notion, and Google Sheets

## Quick overview This workflow runs every weekday, pulls standup messages from a Slack channel, uses OpenAI to generate a structured daily digest, saves the digest to a Notion database, posts a summary back to Slack, and appends an audit entry to Google Sheets. ## How it works 1. Runs every weekday morning on a cron schedule. 2. Fetches the day’s recent messages from a specified Slack standup channel and filters out bot, subtype, and join/leave system messages. 3. Checks whether any standup messages remain and posts a Slack notice if none are found. 4. Formats the remaining Slack updates into a single structured prompt with date, team name, and message count. 5. Sends the formatted standup text to OpenAI (gpt-4.1-mini) to generate a JSON digest with summary, highlights, blockers, per-user updates, and mood. 6. Parses and enriches the AI output with metadata, creates a new page in a Notion database, posts the digest to a Slack summary channel, and appends a run record to a Google Sheets “Audit Log” sheet. ## Setup 1. Add a Slack OAuth2 credential and set the standup channel ID (history source) and the summary channel ID (digest destination). 2. Add an OpenAI credential and confirm the model selection (gpt-4.1-mini) is available in your account. 3. Add a Notion credential, create/select a target database, and replace `YOUR_NOTION_DATABASE_ID` (and ensure the database has the referenced properties: Date, Team, Message Count, Mood). 4. Add a Google Sheets Service Account credential, share the target spreadsheet with the service account email, and replace `YOUR_SHEET_ID` and the sheet name (“Audit Log”) if different. 5. Adjust the schedule cron expression (`0 9 * * 1-5`) to match your team’s standup timing and timezone expectations.

Sync check due dates from Google Sheets to Google Calendar with Telegram alerts

## Quick overview This workflow watches a Google Sheets check inventory list and creates or updates matching all-day events in Google Calendar, then posts a creation or update notice to a Telegram group. ## How it works 1. Polls Google Sheets every hour for any updates in the “Check Inventory” sheet. 2. Checks whether the updated row already contains a Google Calendar Event ID. 3. If the Event ID is empty, searches Google Calendar for an existing event whose text matches the check number and backfills the found Event ID to Google Sheets. 4. If no matching calendar event exists, creates an all-day Google Calendar event using the check date and details from the Google Sheets row, then writes the new Event ID back to the sheet. 5. If an Event ID exists, fetches the corresponding Google Calendar event and compares its date, summary, and description to the latest Google Sheets values. 6. When differences are detected, updates the Google Calendar event to match the sheet and sends a Telegram message summarizing the created or updated events. ## Setup 1. Connect credentials for Google Sheets (including Google Sheets Trigger), Google Calendar OAuth2, and a Telegram Bot API account. 2. Replace `YOUR_CHECK_INVENTORY_SHEET_ID` in all Google Sheets nodes and ensure the “Check Inventory” sheet contains the required columns (including “Check Number” and “Event ID”). 3. Set the target Google Calendar ID (for example `[email protected]` or a shared calendar ID) in the Google Calendar nodes. 4. Replace `YOUR_TELEGRAM_GROUP_CHAT_ID` in the Telegram nodes and edit the message text to use the correct @mentions for your team.
