Original GitHub issue: https://github.com/safijari/openpuck/issues/93
Currently the Steam Controller can pair with 2 pucks on L1+Steam+A and R1+Steam+A slots.
It would be really cool if we could have a easy way to clone OpenPuck paired in one of the slots so the controller can pair with any of them that is on (e.g. turn on Switch 2 it pairs with the NRF52840 connected to it, turn off switch 2 and turn on XBox it connects to the other NRF52840, press btn sequence for slot one, it changes for the PC/SteamMachine with the original puck, no usb plug required)

Working on this today

https://github.com/safijari/openpuck/pull/94 has a backup and restore that I just tested. You can export a json config which you can then import into a new device through a new panel in the webusb. Note that if two pucks are using the exact same config are both powered on and a controller powers on, it'll connect to one at random and stay connected to that one.

This is merged now.

I was wondering if it was possible to extract that needed pairing information from an existing paired controller and/or original Valve Puck?
I'd love to be able to have the controller paired simultaneously both to the original Puck and to an OpenPuck (on the same slot), instead of just to two different OpenPucks.
(Or maybe, in the future, if possible, to two different Steam Pucks in the same slot, if it's possible to manipulate the original puck that way).
I've seen from the JSON backup and the source code that the pairing information is an 8-byte key and then the 16-byte serial number of the controller. Is there a way, with the Steam Controller paired to the original Steam Puck, to figure out the 8-bit key for that pairing? That way one could clone a Steam Puck's pairings onto an OpenPuck.
