By combining data from multiple devices, the Label widget helps you make informed decisions. It is useful in many cases such as:

**Construction**: Display the total energy consumption of a building by aggregating data from all smart meters and sensors.

**Agriculture**: Show the average humidity level across multiple greenhouses to ensure optimal growing conditions.

**Manufacturing**: Present the total output or efficiency rate of production lines by aggregating data from various machines and sensors.

**Smart Homes**: Display the overall air quality index by combining readings from multiple air quality sensors throughout the house.

#### **How to configure**:

1. Select datastreams.
2. Choose aggregation type. You can choose Average, Min, Max, Sum, or Latest value (only if 1 device selected).
3. Narrow down device selection (optional).
4. Design. Navigate to Design tab to configure options such as Background color, Level, and Content Alignment.

Ensure that **Enable History Data** switch is enabled across all used datastreams. Otherwise the widget will not display the data.

1. Navigate to Developer Tools → Templates.
2. Open a template → Datastreams tab.
3. Click on a datastream.
4. Open Advanced Settings.
5. Turn on the Enable history data.
