re: Universal Remote for Apple TV and Amazon Fire Stick?

The Apple TV 4 Siri Remote is Bluetooth, but the ATV still supports IR for most functions, the major exception being the remote's new Home button, Siri, and touchpad gestures.

The Fire TV stick is Bluetooth only, no IR, but it is possible to use adb to gain IP control. I do this with my PC, WMC receiver, and Autohotkey to get IR control, which is way too complicated to get into here. The downside is that the latency is terrible, and the supplied remote is much more performant. That said, it's quite usable while watching shows, and it's mainly frustrating when I want to quickly navigate around the stick's UI, for which I will often pick up the supplied remote.

For the life of me, I don't understand why companies like Apple and Amazon don't publish IP (and IR) protocols for these devices. Amazon actually encrypts the IP communication, so you can't just sniff it with Wireshark or something to reverse engineer and send IP commands directly instead of through the slow adb.

I have no idea if there are Bluetooth-capable universal remotes, and I'm too invested in IR and my favorite remote anyway.
