 # go-weatherstation
 
-Starter go-weatherstationrology data pipeline:
+Starter weather-station data pipeline:
 - MQTT ingest of WS90 payloads -> TimescaleDB
-- Baseline forecast polling (Open-Meteo) -> TimescaleDB
+- ECMWF (Open-Meteo) forecast polling -> TimescaleDB
+- Web UI with live metrics, comparisons, and charts
 
-## Run
+## Quick start
 1) Start services:
-   docker compose up -d
+   `docker compose up -d`
 
-2) Copy config:
-   cp config.example.yaml config.yaml
-   # edit mqtt topic/broker + site lat/lon
+2) Configure:
+   edit `config.yaml` (or `test.yaml`) with your MQTT broker, topic, and site coordinates.
 
-3) Run:
-   go run ./cmd/ingestd -config config.yaml
+3) Run the ingest service locally:
+   `go run ./cmd/ingestd -config config.yaml`
 
-4) Web UI:
-   http://localhost:8080
+4) Open the UI:
+   `http://localhost:8080`
+
+## Configuration reference
+`config.yaml` is the single config file for ingest, forecast polling, and the web UI.
+
+```yaml
+mqtt:
+  broker: "tcp://mosquitto:1883"   # MQTT broker URL
+  client_id: "go-weatherstation-ingestd" # Client ID
+  username: ""                     # Optional username

+  qos: 1                            # MQTT QoS (0, 1, or 2)

+

+  open_meteo:
+    enabled: true
+    interval: "30m"                # How often to fetch forecast data
+    model: "ecmwf"                  # Stored as metadata; endpoint is fixed to ECMWF
+
+web:
+  enabled: true
+  listen: ":8080"                  # Web UI listen address

+  station_id: "YOUR_STATION_ID"
+  station_key: "YOUR_STATION_KEY"
+  interval: "60s"                   # Upload cadence
+```
+
+### Notes
+- The Open-Meteo ECMWF endpoint is queried by the poller only. The UI reads forecasts from TimescaleDB.
+- Web UI supports Local/UTC toggle and date-aligned ranges (6h, 24h, 72h, 7d).
+
+## Schema & tables
+TimescaleDB schema is initialized from `db/init/001_schema.sql` and includes:
+
+- `observations_ws90` (hypertable): raw WS90 observations with payload metadata, plus the full JSON payload (`payload_json`).
+- `forecast_openmeteo_hourly` (hypertable): hourly forecast points keyed by `(site, model, retrieved_at, ts)`.
+- Continuous aggregates:
+  - `cagg_ws90_1m`: 1‑minute rollups (avg/min/max for temp, humidity, wind, uvi, light, rain).
+  - `cagg_ws90_5m`: 5‑minute rollups (same metrics as `cagg_ws90_1m`).
+
+Retention/compression:
+- `observations_ws90` has a 90‑day retention policy and compression after 7 days.
 
 ## Publish a test WS90 payload
+```sh
 mosquitto_pub -h localhost -t ecowitt/ws90 -m '{"model":"Fineoffset-WS90","id":70618,"battery_ok":1,"battery_mV":3180,"temperature_C":24.2,"humidity":60,"wind_dir_deg":129,"wind_avg_m_s":0,"wind_max_m_s":0,"uvi":0,"light_lux":0,"flags":130,"rain_mm":0,"rain_start":0,"supercap_V":0.5,"firmware":160,"data":"3fff000000------0000ff7ff70000","mic":"CRC","protocol":"Fine Offset Electronics WS90 weather station","rssi":-44,"duration":32996}'
