[Flirc with Nvidia Shield Pro 2019 & Kodi]

Before, I had the following setup which worked perfectly well for me:

Harmony 300

Flirc Gen1 for the Harmony attached to a Minix U9H with Kodi

Kodi set up with sophisticated button assignments, e.g. for buttons with all 4 colors

Amazon FireTV Cube with it's own RC

 

Today, I have this:

Harmony 300

Flirc Gen 1 - not in use

Flirc Gen 2 for the Harmony programmed with the "Nvidia Shield Gen2" profi

Nvidia Shield Pro 2019 (works with Flirc, but the power button does not?) & the Kodi app installed

 

What I want to achieve is the following:

control the Shields itself & it's normal apps with the Harmony 300 assigned to one "device" button ("Cable/PC")

&

control the Kodi app ON the Shield with the similar sophisticated button assignments - if needed under a different "device" button ("DVD/Music")

 

I'm not sure if this is possible with one Flirc gen2 device?

Would I maybe need to have two gen2 devices (my Flirc Gen1 is not detected under Windows10 anymore with the latest Flirc software so I can't use it)?

Would I maybe need to make each flirc "listen" to only one RC "device" (there is a way to do such a selection in Flirc I think)?

 

Thanks!
