Variables Blocks

Overview

Variable logic blocks are used to define, store, and transfer data in automation flows. They are the foundation for building flexible and complex logic. With a variable block, you can:

• Define static values: Directly set an initial value of type numeric, boolean, enum, or string for later logic use.
• Receive and store data: Write outputs from other logic blocks into the variable, enabling data flow and temporary state storage. This helps make your logic clearer and easier to maintain.
• Assign and reference dynamically: Variables can be assigned or referenced multiple times during automation runs. You can use them for conditions, calculations, device control, and more.

Using variables flexibly gives your automations stronger data-processing power and better maintainability. For example, you may use a calculation block to get an intermediate result, store it in a variable, and then reference this variable in several places. This avoids repeated calculations and improves overall efficiency.

Supported Types

Aqara Studio supports the following types of variables:

• Boolean variables
• Enum variables
• Numeric variables
• String variables

How to Use Variables

After adding a variable block to the canvas, you can use it in two ways: assigning a value or receiving a value.

• For assigning (manual setting and passing values):
  1. Double-click the variable block. In the settings page, expand Type, set the Value, and click Confirm.
  2. Connect the right node of the Output on the variable block to the left node of Input on the target block.
• For receiving values (using outputs from other blocks): Directly connect the right node of Output on another logic block to the left node of Input on the variable block.
