+The **YoLink** {% term integration %} integrates [YoLink](https://www.yosmart.com/) devices into Home Assistant locally.
+
+## Prerequisites
+
+- YoSmart Local Hub (YS1606)

+- YoLink account
+- Client ID and client secret of the YoLink local API
+
+### Setting up the hub and finding the client credentials
+
