This powerful n8n automation sends you daily weather updates directly to your Telegram chat using live data from OpenWeatherMap. It supports automatic daily updates and manual lookups via form input.

✅ Prerequisites

Before you begin, make sure you have:

  • A working n8n instance (v1.0 or later recommended).
  • An account with OpenWeatherMap (free plan is sufficient).
  • A Telegram Bot created via @BotFather.
  • Your Telegram user ID or chat ID.

🔐 API & Bot Setup

🧩 OpenWeatherMap API

  1. Go to https://openweathermap.org/api
  2. Sign up and verify your account.
  3. Navigate to API Keys in your account dashboard.
  4. Copy your API key (used later in the HTTP Request node).

🤖 Telegram Bot

  1. Open @BotFather in Telegram.

  2. Run /newbot and follow the prompts:

    • Choose a name and username for your bot.
    • You’ll get a bot token (copy this).

  3. Start a chat with your new bot to activate it.

  4. To get your Telegram User ID, use @userinfobot or an n8n Telegram Trigger node.

🔄 Trigger Options

⏰ Schedule Trigger (Automatic)

  • Runs daily at 8:00 AM IST.

🧠 How the Flow Works

  1. Trigger Activated (Scheduled or Form)

    • 📍 City & Country

    • 🌡️ Temperature (°C)
    • 💧 Humidity (%)
    • 🌬️ Wind Speed (m/s)
    • 🔼 Atmospheric Pressure
    • 🌅 Sunrise Time (IST)
