It’s the Data Mapping button. It’s covered in the documentation…

Data Mapping

In case you want to map incoming values to specific range you may use mapping button:

Let’s say your sensor sends values from 0 to 1023. But you want to display values in a range 0 to 100 in the app. When Data Mapping enabled, incoming value 1023 will be mapped to 100.
