Azure IoT Central UI and documentation updates – June 2020
Published date: 15 July, 2020
Dashboards now support visualisations for Event and State telemetry. Event charts display points on a time series to visualise when events occurred from one or more devices. State charts show bars on a timeline representing the duration of states for the selected device(s). To use these charts, add an Event or State telemetry tile and change the visualisation to select Event chart or State chart.
New About page
The About page shows relevant information about your app that’s useful when:
- Contacting support.
- Reviewing your billing information.
- Using the REST API.
- Adding a connector.
View most recent data received timestamp
The Device details page now shows the most recent timestamp generated when a device sent telemetry or a property message. This helps to diagnose if a device is connected and able to send data to the application.
Making IoT Central accessible
Several lists in IoT Central now have a design that’s more accessible to customers using keyboards and screen readers. We’re also working on improvements to our design and engineering processes to ensure that we build an experience that’s accessible to everyone.
Device developer documentation improvements
- A new overview article helps device developers jumpstart their journey with IoT Central.
- The device connectivity article now includes new sample code and provides clarity on symmetric keys and X.509 certificates.
- A new device templates article includes sample snippets and expanded guidance on device capability models, interfaces, properties, commands, cloud properties, customisations and views.
- The Add an Azure IoT Edge device to an Azure IoT Central application tutorial has been updated.
