I assume other devices besides the Nvidia shield have a find my remote feature built in, but it doesn't do one much good if one can only access it via the menu system. Google really needs a "find my remote" much like "find my phone" that cam trigger the find my remote function in these devices.
It can be done if one runs their own home assistant installation, but this should be built in.

Google could learn a lot from Nvidia about how Android TV should work. They seemingly insist however on having OEM's build the cheapest systems possible.Wonder how much adding the remote finder chip to the remote would cost?
