What does Xiaomi AI speaker need to control ordinary TV?

Xiaomi speaker controls other supporting Xiaomi household appliances through the same network WIFI.

But for the time being, you can't control ordinary TV. It is controlled by infrared remote controller.

Now some mobile phones have infrared function and remote control software.

Only by controlling the smart plug of Xiaomi can the power switch of ordinary TV be realized, and the function of changing channels or increasing or decreasing the volume can not be realized.
