Simple vibration chart card with background

Who it’s for

Maintenance engineers, reliability technicians, and plant operators ask “can I see vibration trend and severity at a glance?” The background variant combines a compact sparkline with a full-card color signal for wall-mounted maintenance center displays.

What it does

A device reporting vibration = 2.1 mm/s renders a compact sparkline-style trend line and the current value on a card whose entire background fills with the severity level color: green for Good (below 2.8 mm/s), orange for Moderate (2.8–4.5 mm/s), dark orange for Elevated (4.5–7.1 mm/s), and red for High (above 7.1 mm/s).

• Full-card background color makes vibration severity level readable across a room without reading the number
• Compact sparkline chart shows vibration direction at a glance in a space-efficient layout
• Shows one asset’s data per widget; add multiple widgets to monitor different pumps or motors side by side

How to set up

Data keys

Key	Role	Type	Description
vibration	Chart series	Timeseries	Vibration velocity in mm/s; change the key name to match your device’s telemetry 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 Vibration, 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.

Value ranges

Range (mm/s)	Level	Color
0–2.8	Good	Green
2.8–4.5	Moderate	Orange
4.5–7.1	Elevated	Dark Orange
7.1+	High	Red

How to customize

• To change the severity thresholds — edit the color ranges on the Latest data key to match your machinery class per ISO 10816.
• To change the background colors — edit the color of each range on the Latest data key.
• To rename the units label — change the Units field in the widget settings if needed.

Tips

• On a maintenance center wall display, the colored background announces current machine condition from across the room while the sparkline shows whether vibration is stable, worsening, or recovering after maintenance.
• Use this card when you need both a trend signal and at-a-glance severity status in a compact footprint — for example, one card per critical pump on a machinery health overview screen.
• Use consistent severity colors across all vibration widgets.
