Snow depth card

Who it’s for

City road maintenance crews, ski resort operators, and avalanche risk assessors ask “how deep is the snow right now, and has it crossed an operational threshold?” They need a single at-a-glance value that tells them whether conditions are routine or require action.

What it does

A sensor reading 22 cm shows a dark-blue icon and value — Moderate — so a crew chief scanning a multi-site dashboard can see immediately which stations are still passable. The same card shows light blue at 0 cm — Trace — and orange at 72 cm — Very Deep.

• Color-coded icon and value across six snow-depth bands from Trace to Extreme
• Last-updated timestamp showing how long ago the reading arrived
• Shows one sensor’s data; it does not chart accumulation trends or compare multiple gauges

How to set up

Data keys

Key	Role	Type	Description
snow	Main value	Timeseries	Snow depth in cm; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Snow depth, 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.

The card shows the value in cm with no decimal places. If the key has never reported, the card displays the label and icon with an empty value, not an error.

Value ranges

Range (cm)	Level	Color
0–1	Trace	Light Blue
1–10	Light	Medium Blue
10–30	Moderate	Dark Blue
30–60	Deep	Deep Blue
60–90	Very Deep	Orange
90+	Extreme	Red

How to customize

• To use your own snow-depth thresholds — edit Icon color ranges and Value color ranges; set the same boundaries in both so the icon and the number always agree.
• To change the icon — set Icon to any Material or MDI icon name.
• To hide the label, icon, or timestamp — turn off Show label, Show icon, or Show date.
• To switch to an absolute timestamp — turn off Last update ago in the date format settings.
• To match your dashboard’s fonts — set Value font and Label font.

Tips

• Keep Icon color ranges and Value color ranges on the same boundaries so the icon and the number always show the same band.
• The Very Deep (orange) and Extreme (red) bands are intentionally warm colors against the blue scale — they signal that depth has reached a level where avalanche risk or structural loading becomes a concern, not just that accumulation continues.
• Pair this card with a rainfall card and a temperature card to distinguish active snowfall from compaction of an existing snowpack.
