Hi,
I just got a new Nvidia Shield TV and I am planning to put these boxes around the house, but I’m curious if anyone got Notifications working on these devices.
Would someone be so kind to show their Shield / Notification setup or maybe tell if this isn’t working at all on this device?
Thanks… 
Maybe very late answer and you figured it out already; I was just digging answers to related matter and noted this “open”…
Indeed it is working. What I have is nfandroidtv in place and then suitable automations w/notify in place.
Works every time. It just got updated, and per my knowledge allows images to be send as well (like movement triggered cameras) as notifications - which I am NOT able to get working. Any luck with my question? 
No worries and thanks for the reply though!
I used that integration yes and it works flawlessly.
My mistake I did not post and update myself on this one, as I got it solved.
