Hi there It's a Logitech Harmony 650 I press the button "Off" on the remote, however to get to the shutdown menu I have assigned a button on the remote, E, this is an ok work around but if someone presses "Off" then the mini PC is left on. Just to add if I take the flirc out of the equation, the mini PC does have an infared port and therefore the Kodi profile on the harmony software does turn the machine off using "off", I just like Flirc as theres more functionality (context menus, info buttons all work)
