Thanks for posting in the Community!
It does appear that we have a code for the Xiaomi box: 08184

Thanks for writing in! Sorry to hear you're having troubles as well.
I was able to program the remote for my Panasonic TV. There are no IR settings on the Xioami Mi box,
I found on the WEb that some people use the Logitech Harmony 650 Remote Contro with the Mi Box, therefore I assume that the IR is enabled on this device.
Depending on where your Xiomi Mi box was purchased depends on the control functionality, most are Bluetooth controlled signals. As for how to add it to the Logitech Remote, their forums and support would have the best answer for this solution.
Indeed the Xiomi Mi box uses Bluetooth controlled signals.
Is there any option to pair the soundtouch 700 remote control with the Xiomi mi box 3 using the Bluetooth signals?
The way the Soundbar 700 remote works, is it pairs to the soundbar directly with a unique Bluetooth signature. From here, there are IR blasters built into the soundbar itself which then sends the signals to your third party devices.
Hope this helps!
