Simple power consumption chart card
Who it’s for
Energy managers, plant operators, and sustainability engineers ask “what is the power consumption trend for this asset and what is the draw right now?” They need a compact chart that combines trend and current reading in the smallest possible footprint.
What it does
A device reporting powerConsumption = 8 kW renders a compact sparkline-style trend line and the current value together in a single card, color-coded by consumption level: green for Low (below 5 kW), orange for Moderate (5–15 kW), and red for High (above 15 kW).
- Compact sparkline chart shows power consumption direction at a glance without occupying the space of a full chart card
- Live power reading in kW with color coding across three consumption bands
- Shows one asset’s data per widget; add multiple widgets to monitor different machines or circuits side by side
How to set up
Data keys
| Key | Role | Type | Description |
|---|---|---|---|
powerConsumption | Chart series | Timeseries | Power consumption in kW; 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 Power consumption, 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 (kW) | Level | Color |
|---|---|---|
| 0–5 | Low | Green |
| 5–15 | Moderate | Orange |
| 15+ | High | Red |
How to customize
- To change the consumption thresholds — edit the color ranges on the Latest data key to reflect your facility’s energy budget.
- To change the chart 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
- The simple chart card fits more assets per row than the full chart card — use it for a facility-wide consumption overview where you only need trend direction and current value, not delta percentages.
- A rising sparkline alongside a Moderate reading is an early warning that consumption is moving toward the High band — a useful prompt for an energy check before costs escalate.
- Pair with an efficiency simple chart card on the same row for a two-variable energy-performance panel that fits twice as many machines on screen as the full chart cards.
