Power consumption range chart with background

Who it’s for

Energy managers, plant operators, and sustainability engineers ask “can I see power consumption history by consumption band?” The background variant adds a full-card color signal for wall-mounted energy control room displays.

What it does

A device reporting powerConsumption = 8 kW renders a time-series bar chart where each bar is color-coded by consumption level on a card whose entire background fills with the current consumption level color: green for Low (below 5 kW), orange for Moderate (5–15 kW), and red for High (above 15 kW).

• Full-card background color makes current consumption level readable across a room without reading the number
• Color-coded bar chart makes each interval’s consumption band visible at a glance across the full time period
• Data zoom slider lets operators focus on any time window within the displayed period
• Shows one asset’s data per widget; add multiple widgets to compare consumption patterns across different machines or circuits

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

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 — open the widget settings and adjust the band boundaries to reflect your facility’s energy budget.
• To change the background and bar colors — edit the color for each consumption band in the widget settings.
• To rename the units label — change the Units field in the widget settings if needed.

Tips

• On an energy control room wall display, the colored background announces current consumption status from across the room while the bar chart shows how consumption has varied throughout the period.
• Use this card on a large monitor dedicated to a single machine or circuit where both historical consumption pattern and current status must be legible from a standing position.
• Use consistent consumption colors across all power widgets.
