My receiver is "supported", but no input switching

It also appears that the code set for this receiver is not displaying all of the options, so please look into that too.

We expect to update the firmware before April 10, and the firmware to optimize the infrared learning function is already in the testing phase The APP is also expected to be updated on April 10 to optimize some usage issues Please try to update the firmware after April 10 If you have any problem using X1, please let us know at any time to help you solve it.

I imported the codeset for your receiver. The input codes are there. Might be a glitch in the app.

Yes, I understand how activities work. This is impossible if the underlying device doesn't have programmed functions to send the signals for the source input buttons, which it doesn't for my receiver. The fact that it does for your receiver doesn't change that.

For an example. I have a streaming activity created. When I press the streaming activity my TV comes on switches to the right TV input(HDM1), my Shield powers up, my Yamaha receiver powers on and switches to the correct input(HDMI2). I am ready to go. All by pressing the Streaming activity one time. I never had to press a button to switch the source on either my TV or receiver.

I see several commands after the ones you listed. Among those are several inputs. Yes, I owned a Denon AVR and the source selection are individual buttons on the remote. The way the X1 handles source selection is in an activity. You don't need to push a button because the activity will do the switching for you. As long as the source list is created under the device the activity does the switching. You never have to push the source key on either remote.
