The Xiaomi Home Assistant is a smart home system that integrates with various devices, including smart plugs. However, some users have reported issues with the voltage display on certain plugs, including the qmi.plug.psv3, cuco.plug.cp2d, cuco.acpartner.cp6, and chuangmi.plug.212a01. This article will delve into the problem, provide steps to reproduce the issue, and offer potential solutions. The problem is characterized by an abnormal voltage display on the affected plugs, with some showing a voltage of 0.001 or 0.000001, while others display a constant 220V. To reproduce the issue, users can follow these steps: 1. Connect the affected plug to the Xiaomi Home Assistant system. 2. Check the voltage display on the plug. 3. Compare the displayed voltage with the expected voltage. The expected behavior is that the voltage display should show the actual voltage of the plug. However, in this case, the displayed voltage is incorrect. The Home Assistant logs do not provide any useful information, and the system version is 2024.12.3. The Xiaomi Home Integration version is v0.1.4b0. To resolve the issue, users can try updating the firmware of the affected plugs or checking for any hardware problems. Additionally, users can try resetting the plugs or checking the wiring connections. In conclusion, the voltage display issue on certain Xiaomi smart plugs is a problem that needs to be addressed. By following the steps outlined in this article, users can troubleshoot the issue and potentially resolve it. Further research and development are needed to fix the issue and provide a reliable voltage display on all Xiaomi smart plugs.
