13. Can multiple remotes be paired with a single device?
Yes.
Has anyone had any luck pairing 2 factory remotes to the same unit? I pair one and the other drops out, inoperable.
I’m right there with you buddy. I just opened a ticket.
It is impossible to pair more than one remote at the present time. This functionality was lost with a software update last year. I experimented with three units ; pre-upgrade and post
-upgrade ahoerky after the “upgrade”.
it does not seem to be a hardware limitation or Android O/S limitation, as my AirTV version works flawlessly (with my TIVO remotes)).
I have never been offered a reason why this was done. I feel like this is a “bait and switch” deal, and it pissed me
off. Causes arguments with my wife when we are in bed and I get sick of Forensic Files and have to pry her remote
Out of her cold, dead hand. Lol
