Pressure progress bar

Who it’s for

Meteorologists, weather station operators, and building managers ask “where does the current pressure sit within the full atmospheric range?” They want a bar that positions today’s reading on the global pressure scale so they can see at a glance how unusual the value is.

What it does

A sensor reading 1008 hPa fills the bar to roughly 65% of the 870–1085 hPa scale and colors it green — Normal. A reading of 985 hPa fills to about 50% in red — Low.

• Horizontal progress bar that fills proportionally between 870 hPa and 1085 hPa — the extremes of recorded atmospheric pressure
• Color-coded fill across three bands: Low (red), Normal (green), High (red)
• Current value label shown alongside the bar
• Shows one sensor’s data; it does not chart trends or show a delta

How to set up

Data keys

Key	Role	Type	Description
pressure	Bar value	Timeseries	Atmospheric pressure in hPa; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Pressure, 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, the bar renders empty.

Value ranges

Range (hPa)	Level	Color
< 1000	Low	Red
1000–1020	Normal	Green
> 1020	High	Red

How to customize

• To narrow the displayed range — set Tick min and Tick max to a tighter window (e.g. 960–1040 hPa) to spread out the Normal band and make small pressure changes more visible.
• To use your own pressure thresholds — edit the color ranges; adjust the three default bands to match your operational limits.
• To hide the value label — turn off Show value in the widget settings.
• To hide the entity name subtitle or the timestamp — turn off Show subtitle or Show date.

Tips

• The default 870–1085 hPa scale covers the full historical range of recorded sea-level pressure. If your station is always near 1013 hPa, narrow Tick min and Tick max to a ±50 hPa window so small but significant pressure changes become visible on the bar.
• Use this bar when position-within-range matters. Add the pressure chart card if you also need to see how pressure has been changing over time.
