The Xiaomi Home Assistant has been experiencing issues with the linp.magnet.m1 door and window sensor. The sensor is not accurately reflecting the status of the door or window, showing 'open' when it is actually closed and 'unknown' when it is open. This problem was first noticed on May 15, 2025, at 15:40. The system logs do not provide any response, and the issue is still ongoing. The Home Assistant Core version is 2025.3.4, the Home Assistant Operation System version is 2025.3.4, and the Xiaomi Home Integration version is 0.3.1. To resolve this issue, it is recommended to check the sensor's connection and configuration, and update the integration to the latest version if available. Additionally, resetting the sensor and restarting the Home Assistant system may also help resolve the problem.
