The Xiaomi Home Assistant is a popular smart home device that allows users to control and automate their home appliances. However, some users have reported issues with the device's integration with Home Assistant, specifically with the Xiaomi Home integration version v0.1.2. The problem lies in the fact that the device only has a temperature controller entity and lacks a switch entity, making it impossible to turn the device on or off. To resolve this issue, it is recommended to update the Xiaomi Home integration version to the latest version and ensure that the device is properly configured in Home Assistant. Additionally, users can try using third-party plugins to achieve the desired functionality. With the latest version of Home Assistant Core and Operation System, users can enjoy seamless integration and automation of their Xiaomi Home Assistant device.
