no because i control my multimedia with a Logitech Harmony remote.
The harmony turns on/off all devices according the activity you are doing (watch TV = TV on, soundbar on, decoder on; listen radio = soundbar on, tuner on, tv off etc)
Sadly the harmony remote cannot switch sources directly, only cycle through al of them (bt, wifi, D.in, hdmi1, hdmi2) and this way select the correct one. But the TV has hdmi CEC and switches the source of the bar also. So eachtime it is a guess if the logitech has the correct input source…
So i think Homey knows the activity and you got a great app which can select the source directly, so 1+1 = 2 
I made a flow after homey detects a change of activity of my harmony hub (which is does perfectly) and then let your app switch the correct input source on the bar. BINGO that worked!!
Until i turned everything off…
Then this problem came up, the app switches the soundbar on again…
I solved the problem for now that if activity (powerOff) is executed by harmony then i turn off the soundbar by your app with the command poweroff (and now it stays off)…
But i believe it is unwanted behavior, the app should never turn the soundbar even ON or OFF when this command is not given by you app itself.
The actual live state should always be the default state for the app.
So if someone want to switch the source using your APP and the bar is not turned on yet they should first turn it on with the ON card and then use the INPUT card to switch…
But again, i love the app, i finally (after weeks of frustrating setup problems to get my harmony to get the input correct) got the input working as it suppose to… I could not get it to work without this app!
