Build a dashboard
Start with connected data
Before configuring a dashboard, confirm that your device is sending readings and that its inputs are connected to the intended entity. Use a known sample value — something you can recognise at a glance — to make the first widget easy to verify.
Building a dashboard on top of an unverified mapping means debugging two things at once.
Configure widgets
Open the dashboard
Use Dashboards, or the relevant entity view.
Add and configure widgets
Use the dashboard editing controls to add a widget, then choose the input or data source it should display.
Arrange the layout
Position and resize the widgets for your screen.
Use a current-value display to monitor a reading, and a chart to inspect changes over time. Match the chart’s time range to the period when your device actually sent data.
Validate your view
Send another reading and check that the right widget updates.
If a value is missing, check in this order:
| Check | Why |
|---|---|
| Selected entity | The widget may point at a different asset |
| Input mapping | An unmapped reading has no history to draw |
| Timestamp | The reading may be older than you expect |
| Time range | A chart window that excludes the data looks identical to no data |
Confirm the saved layout by leaving the page and opening it again. A layout that looks right but was never saved will not survive a reload.
Dashboard values update live as readings arrive. If values update but the chart does not fill in, you are seeing live data without stored history — which points back at entity mappings.
Sharing a dashboard
A dashboard can be shared through a link that does not require the recipient to sign in to the workspace. A shared dashboard can be protected with a password; without one, treat the link as public to anyone who has it. Only share views you are comfortable exposing, and set a password when the data is sensitive.
