Relay Attentuator and Picore

Allo released a device to be mounted on top of their devices. It is fixing the volume to 100 and enhancing the sound in a positive way

But it works only on Volumio.

Thanks to Paul he shared the codes for it to work with piCore but applying them all is beyond my knowledge :/ It’s not a simple ssh operation I suspect.

Anybody who used and made it work at piCore?
