The Amazon Alexa Voice Remote (3rd Gen) works for compatible Fire TV streaming players including Fire TV Stick Lite, Fire TV Stick (2nd Gen and later), Fire TV Stick 4K, Fire TV Cube (1st Gen and later), and Fire TV (3rd Gen, Pendant Design). It connects via Bluetooth to supported Fire TV devices and uses IR to control TV power, volume, and mute functions, with no programming required for compatible models. This remote does not work with Fire TV (1st or 2nd Gen), Fire TV Stick (1st Gen), or Fire TV Edition smart TVs.
