Open-Meteo Weather Station Feed

How it works

This LoT Notebook polls Open-Meteo for current conditions in Minneapolis every 5 minutes and turns the response into a clean topic tree on Coreflux. It solves the common problem of normalizing live weather data into stable metric topics, unit twins, and a report model that other consumers can read.

Key features

• Self-starting clock: An action bootstraps demo/weather/feed/enabled and triggers polling on a 5-minute interval.
• REST_API route: Fetches current weather from Open-Meteo with no API key or credentials.
• Payload gate: Rejects non-JSON or invalid replies and publishes fetch_error instead of stalling the flow.
• Metric-primary topics: Publishes SI values on base topics and imperial twins with _f / _mph suffixes.
• Metadata topics: Keeps _EU display symbols and _DESC descriptions alongside live values.
• Weather report model: Builds one collapsed WeatherReport JSON document per refresh.
