Nope. CEC too, just like I said. I'm controlling 4 Fire sticks that way as we speak. I posted the above codes for a Vizio TV which get relayed to the stick via HDMI. Works fine except for Menu, which is rarely used anyway. To use CEC, just use the corresponding playback and nav commands for your TV. Obviously if you don't have a Vizio TV, my posted codes won't work.

Control from a phone is for the birds, IMO, except for text entry.
