## Introduction to Xiaomi Home Assistant
The Xiaomi Home Assistant is a smart home system that integrates various devices to provide a convenient and automated living experience. However, like any other technology, it can sometimes encounter issues. This article aims to address a specific problem where the left and right key clicks on a Xiaomi smart wireless switch are not being received, showing as 'unknown' in the Home Assistant.
## Step-by-Step Reproduction of the Issue
To understand and potentially resolve the issue, it's crucial to follow a systematic approach to reproduce the problem. This involves setting up the Xiaomi smart wireless switch (dual-key) within the Home Assistant environment and observing the behavior of the left and right key clicks.
