The Xiaomi Home Assistant is a smart home system that integrates various devices, including Bluetooth-enabled devices. However, some users have reported issues with the Bluetooth connection after updating the system. This article will delve into the problem, its causes, and potential solutions. The issue at hand is the loss of connection between the Bluetooth device and the Xiaomi Home Assistant, which occurs after the system update. The error message 'local mips state changed, mips not exist, 4fc32ff88b7758bd' is reported in the system logs. To reproduce the issue, the user needs to configure the device with the 'automatic' option instead of 'cloud' and wait for 5-10 hours. The expected behavior is that the system should be able to reconnect to the device after the update. The problem was first reported on March 24, 2025, at 14:13. The system logs show that the 'custom_components.xiaomi_home.miot.miot_client' module is the source of the error. The Home Assistant Core version is 2025.3, and the Operation System version is 13.0. The Xiaomi Home Integration version is the latest. To resolve this issue, it is recommended to add a feature to search for the mips. This can be achieved by modifying the 'miot_client.py' file to include a function that periodically checks for the mips and reconnects to it if it is lost. Additionally, users can try restarting the device and the Xiaomi Home Assistant to see if it resolves the issue. It is also essential to ensure that the device is properly configured and that the Bluetooth connection is stable. In conclusion, the issue with the Bluetooth connection in the Xiaomi Home Assistant can be resolved by adding a feature to search for the mips and by troubleshooting the device configuration and Bluetooth connection.
