The Xiaomi Home Assistant is a powerful tool for managing and monitoring home devices, but some users have reported issues with the power curve display in history cards. This article will describe the problem, provide steps to reproduce it, and offer a solution to improve the visibility of power curves in history cards. The issue arises when the state_class field is missing from the power sensor, causing all data points to stack together and making the curve impossible to read. By adding the state_class: measurement field to the power sensor, the curve will be downsampled, and the maximum, minimum, and average values will be displayed, making it easier to interpret. This solution is essential for users who want to monitor their energy consumption effectively. With the Xiaomi Home Assistant, users can control and monitor their devices remotely, receive notifications, and access a wide range of automation features. The device integration version, v0.1.2, and Home Assistant Core version, 2024.11.0, are crucial in ensuring the system's stability and functionality. By following the steps outlined in this article, users can resolve the power curve display issue and enjoy a more seamless experience with their Xiaomi Home Assistant.
