- Definition: "a feeling that you are happy and your mind and emotions are well balanced" Macmillan Dictionary. This is the end result of this little miracle. I bought my first Harmony remote back in 2003 to control with one button a myriad of home entertainment devices. It brought harmony back to our household and replaced pages of instructions on how to watch programming from different sources. No more set the TV to Input 1, the receiver to audio input 2, A/V switch to position B; so on and so forth. I now have two of these babies and could not live without them.
