Querying and adjusting the Roku TV's volume

Are there plans to expose the TV's volume level and/or volume control in the api?

I would like to automate my Roku TV's volume in response to events (e.g. when it is 8pm, turn volume to  X or change the input to PlayStation and set volume to Y)

Device Info:
<vendor-name>TCL</vendor-name>
<model-name>65S403</model-name>
<model-number>7106X</model-number>

        Amazon Alexa can also set the volume on my TCL Roku TV to a specific value. I can say "Alexa, set family room TV volume to 55" and the volume gets set, so there must be a command that Alexa is using to set the volume directly.

    Have you tried these?
    https://sdkdocs.roku.com/display/sdkdoc/External+Control+API#ExternalControlAPI-ExternalControlServiceCommands

    Some Roku devices, such as Roku TVs, also support:
    VolumeDown
     VolumeMute
     VolumeUp
     PowerOff
    Roku TV devices also support changing the channel when watching the TV tuner input:
    ChannelUp
      ChannelDown
    Roku TV devices also support keys to set the current TV input UI: InputTuner
     InputHDMI1
     InputHDMI2
     InputHDMI3
     InputHDMI4
     InputAV1

    Yes, I am aware that I can send commands to increase/decrease the TV's volume, but I do not believe there is a way to know what the current volume level is or whether or not the TV is muted.

    If I knew the level, then I could send the correct number of increases/decreases to adjust the TV to the desired volume

    worst case you could probably send 100 volumedown's in a row then assume it's at 0

    yea, but that seems kludgey.... I did run a quick test and it takes ~30seconds to go from 100 to 0.... which would get annoying if I had the volume adjust when ever I open the Netflix app.

    yeah it's definitely a hack, I could be wrong but my guess is you will be waiting a long, long time for Roku to add any such feature (expose TV's volume) assuming it's possible..
