Has anyone managed to get Home Assistant’s Onkyo integration to select “WHOLE HOUSE MODE”? On my Onkyo receiver, there is a “Whole House Mode” button that when pressed, simultaneously outputs to my Zone 1 speakers, as well as the Line Out on Zone 2 and Zone 3.
If I look at the HA Lovelace UI after pressing Whole House Mode, both Zone 2 and Zone 3 are turned on and are set to a source named “source” according to HA’s Developer Tools, but if I set that manually in HA it doesn’t have the same effect.
Strangely if I manually set Zone 2 and 3 in Home Assistant or on the receiver to the same source, I don’t get any output on the Line Outs. I have to use “Whole House Mode” to do it…
