The Xiaomi Home Assistant is a powerful tool for controlling and automating various aspects of your home. One of its features allows users to set a custom no-motion time, which can be used to determine when to turn off lights after a certain period of inactivity. However, a recent bug has been reported where the custom no-motion time is not working as expected, causing lights to remain on even when there is no motion. In this article, we will explore the issue and provide a solution to customize the no-motion time for automated lighting control. The user had set a custom no-motion time of 1 minute and created a template to judge whether someone is moving based on the custom no-motion time. However, the system suddenly changed to 0 minutes at 19:40:27, causing the automation to incorrectly identify someone as present and keeping the lights on. To resolve this issue, it is necessary to optimize the judgment and allow users to freely set the no-motion time to turn off lights after a certain period of inactivity. By doing so, users can enjoy a more automated and efficient home experience.
