What Is It?

A free Niagara 4 module that fetches real-time weather data from Open-Meteo (a free, no-API-key-required weather service) and writes it directly into Niagara points.

Data Available

• Current temperature, humidity, wind speed
• Weather condition code (sunny, cloudy, rain, etc.)
• 7-day forecast data
• Configurable city/location

---

Quick Start

# 1. Install gline.pem certificate (or skip if other gline modules already installed)

# 2. Add glineCurlWeather-rt.jar to your modules/ directory

# 3. Restart station

# 4. Configure your city coordinates (latitude/longitude)

# 5. Enable → weather data flows into your station points

The module uses the gline-prefix certificate. If you've already installed other gline jar packages, re-importing the certificate is not necessary.
