Amazon FireTV remote is pretty good, latest gen added a volume control inc. mute button (so you don't need your TV remote). Source switching uses CEC over HDMI.

Amazon FireTV remote is pretty good, latest gen added a volume control inc. mute button (so you don't need your TV remote). Source switching uses CEC over HDMI. You don't need to point the controller for most tasks as it's Bluetooth. If I had a TV that used CEC I wouldn't need the original remote at all.
