To anyone that would be as kind as to assist!
I have the Velleman K8056 relay board, which I have connected to a USB to Serial Converter and successfully works in both Linux and Windows.
I am also comfortable with setting up the commands/automation with the board in HA, however the challenge I have is that I need to compile a utility to enable control in Linux.
Unfortunately as we all know the HA OS - core-ssh does not have the utilities required to compile the simple utility.
How could I either compile a compatible Binary on another Linux system or add packages to the underlying OS to enable this?
