Last updated
Displays static formatted text with your choice of font style, horizontal and vertical alignment, and color.
If the widget has a datastream on, it can show its value via placeholder '/value/' put in the text option in settings.
A formatted label for the widget is optional.
Select or create a datastream of data type integer, double, enumerable, string. The datastream is used to insert a corresponding value inside the text the widget is showing, and for holding and assigning the widget properties of vertical and horizontal alignment, font style and color.
The widget has no controls.
Text - the formatted text you want to appear in the widget. Alignment as left, center, right justified can be assigned in Design tab. Use placeholder '/value/' to show the datastream value inside the text.
Title - the widget label that appears above the formatted text.
Value - format options for the displayed text assigned under ‘Settings’. Font style, horizontal & vertical alignment, and text color.
Not applicable. This widget only displays the text and the datastream value, it does not allow it to be changed from the UI.
You can change certain properties of the Widget from your hardware. For that, use this command:
Where:
vPin is: virtual pin number the widget is assigned to
widgetProperty: property you want to change
propertyValue: value of the property you want to change
Don't put Blynk.setProperty()into the void loop() as it can cause a flood of messages and your hardware will be disconnected. Send such updates only when necessary, or use timers.
You can change the properties label, color, isDisabled, isHidden of the widget from your hardware, or via an HTTP API. The URL must be encoded, so spaces in labels must be replaced with %20, and color hexadecimal values in the HTTP API URL must include the hash # character urlencoded as %23.
Widget will be greyed out on UI and users won't be able to tap on it.
Widget will be hidden from dashboard. Design your UI so that it doesn't look weird when there is no widget.
GET https://{server_address}/external/api/update/property?token={your 32 char token}&pin={your vPin}&{property}={value}
The endpoint allows you to update the Datastream Property value via GET request. All widgets (both web and mobile) that are assigned to this datastream will inherit this property. The Datastream Property is persistent and will be stored forever until you change it with another value. In order to clear the property you need to clear the device data in device actions menu.
Example:
https://blynk.cloud/external/api/update/property?token=GVki9IC70vb3IqvsV0YD3el4y0OpneL1&pin=V2&label=My%20Label
https://blynk.cloud/external/api/update/property?token=GVki9IC70vb3IqvsV0YD3el4y0OpneL1&pin=V1&color=%23D3435C

You can update your hardware to the latest datastream value from Blynk.Cloud after your hardware went offline, and then came online again. Use Blynk.syncVirtual() to update a single virtual pin, or Blynk.syncAll() to update all virtual pins. See State Syncing for more details.
Get from the bottom right of your Blynk console. .
