How to register a Xiaomi TV: 3 working methods + error solving

Without being linked to your Mi Account, you won’t be able to use Xiao AI’s voice assistant, synchronize settings between devices, or manage TV through the Mi Home app, and many users experience log-in errors ranging from internet connection issues to account lockdowns due to suspicious activity.

In this article, we will discuss all the current ways to register Xiaomi Mi TVs (including Mi TV 4A/4S/4X/5/5X/6/Q1/Q2/A Pro models), explain why it is necessary, and show how to solve errors. If you just bought a TV or reset it to factory settings, the manual will also work for you.
