Does anybody know of a usb-c hub that can connect at the wall power plug instead of at the MacBook? The data and power would be carried by the long 2 meter usb-c cable that comes with the MacBook.
The charger cable that comes with the MacBook is just that: a charger cable. It doesn't support data transmission.
You just need a new cable, and a hub with a female data input rather than a built-in male cable, and you're set.
