Bought this to control my portable AC/Heat pump by voice (Alexa/Google). It is able to control the unit with the correct IR codes. But it is very limited to what you can do with the voice commands. You cannot set it to just fan mode by voice and controlling the fan swing is not possible either. I am now using 3 ifttt applets that kinda work: trigger heat trigger cool trigger fan Still need to use the original remote do set certain things, which defeats the purpose.
