Hi folks, I managed to get it working on a rapsberry pi 2 (isengard) with the only available version 0.8.4
Configure the pvr stalker (let it enabled), let tv setting on off in Kodi.
Than reset your nfps papaio :https://papiao.is/main/search_nfps and at nearly the same moment change kodi tv setting to ON.
Reboot and this worked for me.
