Weather Fusion Guide

Weather Fusion connects your Davis personal weather station to iPhone, iPad, and Mac.

When a WiFiLogger is on your network, the app retrieves the same live readings you see on the console over Wi-Fi. If you publish data through WeatherLink, Windy, or Wunderground, you can link those accounts and use them as alternate sources inside the app.

The real-time dashboard presents live measurements in a clean, elegant layout that stays readable at a glance.

The Trends view surfaces archived observations from WiFiLogger and supported services, pairing historical context with current conditions in the same refined style.

Welcome to Weather Fusion

Weather Fusion brings together local WiFiLogger data and cloud services so you can check conditions anywhere. Launch the app on iPhone, iPad, or Mac to see the same trusted readings from your Davis console with a layout tuned for quick scanning.

Use Weather Fusion as your daily hub: the Real-Time Dashboard shows live measurements, the Trends screen reveals historical context, and the Observation Archive keeps deeper records at your fingertips.

Fist Launch

Local WiFiLogger Setup

Choose WiFiLogger during setup to work directly with your on-premises device.

Select Continue to automatically scan your local network for a WiFiLogger. Allow Local Network access if prompted.
Enter the hostname or IP manually when needed (for example, wifilogger.lan or 192.168.1.50).
Use Scan Network and Test Connection to confirm Weather Fusion can reach the logger before you finish setup.
If you want to explore without hardware, point the WiFiLogger endpoint to wf-demo.lan to load demo data.

Weather Fusion polls WiFiLogger roughly every five seconds for the richest set of metrics.

Remote Data Source Selection

Weather Fusion can also read from remote services when a local logger is unavailable or when you need access away from home.

WeatherLink (API v1) streams data from weatherlink.com.
Weather Fusion Cloud mirrors your station to weatherfusion.app so you can fetch current data from anywhere.
Set Up Later loads the demo station so you can tour the interface without signing in.

Remote sources can be switched on any time from Settings and used as fallbacks when WiFiLogger goes offline.

Remote Credential Configuration

Prepare your credentials before entering them in Weather Fusion:

WeatherLink (API v1): enter your Device ID, Password, and API Token V1 from weatherlink.com/account.
Weather Fusion Cloud: enter your Station ID as assigned on weatherfusion.app.
Fallback behavior: pick a configured remote source as the automatic backup when WiFiLogger fails to connect.

Real-Time Dashboard

Current Conditions Overview

The dashboard combines live measurements with context so you can see temperature, wind, rain, and radiation data at a glance. Use the toolbar toggle (or press ⌘⇧G on macOS) to swap between the compact Gauges view and the detail-rich Data view.

Live Highlights (Rain, Wind, UV Chips)

Highlight tiles emphasize rapidly changing metrics:

Rain tracks rate and accumulation so you can spot spikes the moment they start.
Wind shows speed, gust, and direction, matching the compass orientation from your station.
UV and Solar badges call out high exposure levels when your sensors support them.

These highlights appear in both views so you never miss meaningful changes.

Forecast Blurbs

Content placeholder: Upcoming forecast blurbs will summarize near-term outlooks alongside live data.

Gauge View Metrics

The Gauges view presents compact dials for the most important readings:

Temperature gauges include today’s low/high markers so you can see daily extremes.
Wind gauges combine compass direction, speed, and gust in a single radial control.
Rain, Humidity, Pressure, Solar, UV, and ET gauges provide quick trend cues.
Adjust visual ranges in Settings > Gauges using the Climate Region presets that match your environment.

Data View Metrics

The Data view stacks cards with richer context, including historical comparisons and trends:

Temperature, Wind, Rain, Pressure, Solar & UV, ET, and Station Map cards mirror the data set from your selected source.
Cards update as quickly as the source allows (about every five seconds for WiFiLogger, roughly once per minute for WeatherLink).

See the Weather Data Reference section for a full breakdown of each metric.

Station Details

Open Window > Station Details on macOS, or scroll to Station Info at the bottom of the Data view on iPhone and iPad, to review firmware versions, Wi-Fi signal, IP address, and location metadata for your station.

Settings & Tools

Real-Time Data Source Settings

Pick your primary live source in Settings:

WiFiLogger uses a local address or IP for the fastest updates.
Configure Weather Fusion Cloud or WeatherLink to act as backups when WiFiLogger cannot connect.
Set fallback switching to Off if you prefer manual control.

Weather Fusion only attempts the fallback after a WiFiLogger connection error, keeping your preferred source active when everything is healthy.

Trends Data Source Settings

Content placeholder: Document configuring archival sources that power the Trends screen.

Gauge Presets

Choose a Climate Region preset to tune gauge ranges:

Global provides a wide default envelope.
Regional presets (Temperate, Tropic, Arid/Desert, Polar) make gauges feel responsive for your local climate.

Find this under Settings > Gauges as Temperature Preset.

Units & Measurement Preferences

Set preferred units for Temperature, Wind Speed, Pressure, Rain, and Elevation. The dashboard and Settings reflect your changes immediately.

Manual Backup & Restore

Content placeholder: Instructions for backing up and restoring Weather Fusion settings will appear here.

WiFiLogger Device Tools

When WiFiLogger is the active source, additional device tools appear:

Local Address / IP: enter the hostname or IP (for example, wifilogger.lan).
Scan Network: discovers WiFiLogger automatically and fills the address.
Test Connection: verifies Weather Fusion can reach the device.
Station Configuration: edit station name, latitude, longitude, and elevation (entered in feet on the device, displayed using your chosen units). Use Current Location to fill coordinates automatically, then Save to apply changes.
Device Actions: open the WiFiLogger web interface or send a safe restart command; Weather Fusion pauses polling and reconnects once the device returns.

If WiFiLogger settings are hidden, enter a valid local address to unlock them.

Weather Data Reference

Detailed reference for the Data view cards. Available metrics vary by source: WiFiLogger delivers the broadest set, updating roughly every five seconds; WeatherLink provides a smaller subset about once per minute.

Temperature & Humidity

Temperature reflects the current outdoor sensor reading and shows today’s range when available.
Humidity expresses current relative humidity; higher values can make warm air feel hotter.
Dew Point marks saturation temperature; when close to ambient temperature, conditions feel muggy.
Heat Index blends heat and humidity for a “feels like” value.
THW Index combines temperature, humidity, and wind to reveal comfort differences on breezy days.
Wind Chill estimates perceived cold; it matters when air temperature drops below about 10 °C / 50 °F.

Wind

Wind Speed shows the latest 2–3 second average.
Gust flags short bursts above the average.
Direction tracks compass heading and updates with each packet.
10-minute average and high/low markers appear when supplied by the source.

Rain

Rain Rate displays the current hourly intensity.
Storm, Daily, Monthly, and Yearly totals appear once the underlying service provides them.
“Since Midnight” counters reset automatically each local day.

Pressure

Barometric Pressure reports current sea-level corrected pressure.
Trend arrows and textual descriptions warn of rising or falling systems.

Solar & UV

Solar Radiation shows watts per square meter from compatible sensors.
UV Index highlights exposure risk with category shading.
Sun hours and high/low markers appear when available.

Evapotranspiration (ET)

ET tracks moisture loss from soil and plants.
Daily and Weekly totals help plan irrigation scheduling.

Weather Station Map

Displays station location, pulling coordinates from WiFiLogger or your configured source.

Troubleshooting

Work through these checks if data stops flowing:

Ensure your Mac, iPhone, or iPad is on the same network as WiFiLogger and that Local Network access is allowed in system privacy settings.
After power cycles, give the Davis console a moment to resume broadcasting—low transmitter batteries can slow updates.
Restart WiFiLogger from Settings > WiFiLogger Device Tools > Restart WiFiLogger when the device becomes unresponsive.
Refresh manually with ⌘R on macOS or a pull-to-refresh gesture on iOS to force an immediate update.
Avoid VPNs or restrictive firewalls during setup, and enter the WiFiLogger IP manually if discovery fails.
