So, according to the advice, I placed the question on the Kodi forum. Best regard, meda20

But I will answer why I chose RPi ZERO.

The only service is to send UPnP from a connected USB drive, without additional requirements on the interface, with a small power consumption of up to 2W (certainly less) for 24/7.

If I own ZERO, it's a shame not to use it.
