njordMulti-model weather intelligence for Home Assistant

Poll any combination of 50+ weather models per location, enrich forecasts with consensus, alerts, trends, and more, and publish everything to Home Assistant via MQTT Discovery.

Getting Started

Config Builder

Multi-model forecasts

Poll multiple weather models per location — ICON, ECMWF, GFS, UKMO, MeteoSwiss, and regional models — each published as a dedicated Home Assistant device with hourly and daily sensors.

Enrichment pipeline

Consensus forecasts, weather alerts, derived values (Beaufort, wind chill, comfort), trend analysis, activity indices, and forecast accuracy tracking — all configurable.

Weather alerts

Frost, heat, storm, heavy rain, UV, fog, snow, pressure drop, and thunderstorm alerts derived directly from model data — no third-party alert service required.

Low resource usage

Runs as a single .NET container on any Docker host. SQLite persistence by default, no external database needed. Respects Open-Meteo free-tier rate limits out of the box.
