This workflow automates plant care reminders and records using Google Sheets, Telegram, and OpenWeather API. It checks when each plant needs watering or fertilizing, sends a personalized reminder, and lets you confirm the task with a single button. When confirmed, it updates your Google Sheet and shows a confirmation HTML page. Who is it for? Home gardeners who want to automate watering and fertilizing schedules. Anyone managing a plant collection, greenhouse, or garden and wanting a lightweight, no-code reminder system. How it works Schedule Trigger starts the workflow once per day. Read Settings (Google Sheets) checks if vacation_mode is active. Read Plants (Google Sheets) retrieves all plants with columns such as id, plant, last_water, water_freq, etc. DecideDue (Code Node) compares today’s date with the last watering/fertilizing date and marks which plants are due. OpenWeather Request (optional) fetches local forecast for plants with coordinates and weather_delay = true. WeatherGate (Code Node) skips or delays watering if it recently rained or if rain is expected soon. Telegram Send Message sends a reminder for each due task. The message contains an inline button “Mark as done” linking to your webhook URL (opens confirmation window). Webhook – Confirm Done receives the click, update dates on Google Sheets, appends an optional log entry, and returns an HTML confirmation page.
