It is indeed just a usb-c to ethernet dongle. Was not aware it would need to power the device as well. Weird choice not to provide an ethernet adapter in the box, and even weirder that it would need to be POE, why not treat this as just another USB adapter.
The reason for trying to find a cheaper dongle was that the original is more than twice the price of this. And the Homey pro is already rather expensive.
