All IoT Dashboards are constructed using ThingsBoard widgets defined in the Widget Library.

A widget is an element that displays a specific type of information or functionality on a dashboard. Widgets are used to display data and visualize information obtained from devices connected to the ThingsBoard platform, remote device control, alarms management, and display static custom HTML content.

According to the provided features, each widget definition represents a specific widget type. There are five widget types:

Latest values;
Time series;
Control widget;
Alarm widget;
Static widget.

The widget type is displayed in the corresponding column on the "Widget Library" page.

Each widget type has its own specific data source configuration to visualize data. Types of available data sources depend on widget type:

Alarm source - this data source type, used primarily in Alarm widgets, requires a source entity to display related alarms and their corresponding fields;
Alarms count - this data source type is used in latest values widgets. You need to specify the target entity;
Device - this data source type is used in both time-series and latest values widgets. Basically, you need to specify the target device, and the time series key, or the attribute name, or entity field;
Entities count - this data source type is used in latest values widgets. You need to specify the target entity;
Entity - this data source type is used in both time-series and latest values widgets. Basically, you need to select the target entity by specifying an entity alias, and the time series key, or the attribute name;
Function - this data source type is used in both time series and latest values widgets for debugging. Basically, you can specify a JavaScript function that will simulate data from a device in order to set up visualization.

Latest values

The Latest values widget type is designed to showcase the latest values of a specific entity attribute or time series data point (e.g., any Gauge Widget or Entities Table widget). This type of widget uses values of entity attribute(s) or time series as a data source. Digital Gauge in the example is displays the current temperature value.

Time series

The Time series widget type displays historical values for the selected period of time, or the latest values in the certain time window (e.g., Timeseries Line Chart or Timeseries Bar Chart). This widget type uses only the values of entity time series as a data source. In order to specify the time frame of displayed values, Timewindow settings are used. The timewindow can be specified on the dashboard page or via widget details. It can be either Realtime - the dynamically changed time frame for a certain latest interval, or History - a fixed historical time frame. All these settings are part of Timeseries widget configuration. In the example, the “Timeseries Line Chart” displays the speed value of the device in real-time.

An example of timeseries widget is the "Timeseries Line Chart". It displays temperature values of devices in real-time.

The Control widget allows sending RPC commands to devices, it handles and visualizes replies from the device (e.g., Raspberry Pi GPIO Control). The RPC widgets are configured by specifying the target device as the target endpoint for RPC commands. In the example, the “Basic GPIO Control” widget sends GPIO switch commands and detects the current GPIO switch status.

An example of RPC widget is “Basic GPIO Control”. It sends GPIO switch commands and detects current GPIO switch status.

The Alarm Widget type displays alarms related to the specified entity in the certain time window (e.g., Alarms table). To configure the Alarm widget, you designate an entity as the alarm source and define the corresponding alarm fields. As the Timeseries widgets, Alarm widgets have the timewindow configuration to specify the time frame of the displayed alarms. Additionally, the configuration includes parameters such as “Alarm status”, “Alarm severity”, and “Alarm type”. The “Alarm status” parameter shows the status of the alarms being fetched. The “Alarm severity” parameter shows the frequency of alarm fetches in seconds. The “Alarm Type” parameter helps identify the primary source of the alarm. For instance, “HighTemperature” and “LowHumidity” represent two different alarms. In this context, the “Alarms table” widget displays the latest alarm for the device in real-time.

Alarm widget is configured by specifying an entity as the alarm source, and the corresponding alarm fields;

An example of Alarm widget is the “Alarms table” widget that displays the latest alarm for the device in real-time.

Static

The Static widget type displays static customizable HTML content (e.g., HTML card). Static widgets don’t use any data sources and are usually configured by specifying static HTML content and, optionally, CSS styles. An example of a Static widget is the “HTML card” that displays the specified HTML content.

An example of a Static widget is the “HTML card” that displays the specified HTML content.

font-size: 32px;
color: #999;
width: 100%;
height: 100%;
display: flex;
align-items: center;
justify-content: center;
}

<div class='card'>Your text here</div>

Widgets Library (Bundles)

Widgets are grouped into widget bundles according to their purposes. Some widgets can be found in multiple packages simultaneously. For example, the Alarm Count widget can be both found in the Alarm widgets bundle and the Count widgets bundle.

There are system-level and tenant-level widget bundles. Initial ThingsBoard installation comes with a basic set of system-level widget bundles.

The system-level bundles can be managed by a System administrator and are available for use by any tenant in the system. The tenant-level bundles can be managed by a Tenant administrator and are available for use only by this tenant and his customers. You can always implement and add your widgets by following this guide.

To find the widget you need among all the widget bundles, you can use the search function.

You can also find the widget you need by its name on the “Widgets” tab. Here, all available widgets are listed by default in alphabetical order.

When a system administrator adds a new widget, it automatically becomes a system widget. This means that only the administrator has the privilege to modify, or delete the widget. Tenant administrators can also create widgets, but they are granted permission to modify only the widgets they have created. You can always implement and add your widgets by following this guide.

To add a new widget, you should:

Navigate to the "Widgets Library" page using the main menu on the left. Click the "+" icon in the upper right corner of the screen, and select the "Create new widget" option from the drop-down menu;
In the pop-up window select widget type;
In the dialog window that appears, enter the name of the new widget, input the widget JavaScript code, and then click "Save" to complete the widget creation;
The new widget is created.

You can export a specific type of widget from a widget bundle in JSON format, and import it in the same or different ThingsBoard instance.

In order to export a widget type, you should go to the Widgets Library page, navigate to the “Widgets” tab and click the export button on the particular widget card. The widget configuration file will be saved in JSON format on your computer.

Click the export button on the particular widget card. The widget configuration file will be saved in JSON format on your computer.

Please note that only system administrators can modify system (default) widgets. This includes the ability to edit, delete, add, or import widgets within the bundle. When a system administrator creates a new widget bundle, it’s set as a system-level item for tenants, preventing them from modifying it. Nevertheless, tenants can add their own widgets. In this case, they have full rights to manage created widget types inside the bundle.

To import a widget, you should:

Click the "+" button in the upper right corner of the "Widgets" page. Select "Import widgets type" from the drop-down menu;
In the pop-up, you will be prompted to upload the JSON file. Drag and drop a file from your computer, then click the "Import" to add a widget to the widget bundle;
The widget is imported.
