Simple wind speed chart card

Who it’s for

Outdoor event organizers, wind energy operators, and smart farming teams ask “how has wind speed changed over the day, without the clutter of delta comparisons?” They want to see the current speed and the daily curve in one card, nothing more.

What it does

A sensor currently reading 12.5 m/s shows a deep blue value — Fresh — above a chart that reveals the wind pattern over the selected time window: calm overnight, rising through the morning, peaking in the afternoon, then easing as the evening cools.

• Large current wind speed value color-coded across seven Beaufort-inspired bands from Calm to Storm
• Time-series chart of wind speed readings over the selected time window, averaged per interval
• Shows one sensor’s data; it does not show wind direction, compare multiple sensors, or show period-over-period deltas

How to set up

Data keys

Key	Role	Type	Description
speed	Chart series	Timeseries	Wind speed (m/s); drives the chart. The Latest value overlay is automatically derived from this same key
Latest	Latest value	Timeseries	The headline figure above the chart. Its own color ranges are where the band colors are edited

The widget ships with a simulated function datasource key labeled Wind Speed, so it draws random values until you point the datasource at a device and rename the key.

To point it at your own device: open the dashboard in edit mode, open the widget’s Datasources, pick the entity or entity alias, and replace the function key with the key your device reports.

If the key has never reported for the selected time window, the chart is empty and the value overlay shows no data.

Value ranges

Range (m/s)	Level	Color
0–0.2	Calm	Light Blue
0.2–3.4	Light	Blue
3.4–8	Gentle	Medium Blue
8–10.8	Moderate	Dark Blue
10.8–17.2	Fresh	Deep Blue
17.2–24.5	Strong	Red
24.5+	Storm	Dark Red

How to customize

• To use your own wind thresholds — edit the color ranges on the Latest data key; adjust the seven default bands to match your operational or safety thresholds.
• To hide or show the chart — toggle Show chart in the widget settings.
• To change the chart line color — set Chart color.
• To hide the entity name subtitle or the timestamp — turn off Show subtitle or Show date.
• To match your dashboard’s fonts — set the font options under each data key’s appearance settings.

Tips

• Use this card when the daily wind pattern matters more than the exact period-over-period change. Add the full wind speed chart card if you need a delta m/s figure alongside the chart.
• The seven bands align broadly with the Beaufort wind scale; Strong (≥ 17.2 m/s, Beaufort 7) is the common threshold for halting outdoor crane operations, and Storm (≥ 24.5 m/s, Beaufort 10) triggers structural-risk alerts for tall cranes and masts.
• Wind speed is typically averaged over 10 minutes for operational decisions; large swings within a short time window visible in the chart indicate gusty conditions that may warrant a higher effective alert threshold.
