I'm trying to implement mute toggle for Denon via IP control. Unfortunately Denon does not have command to directly toggle mute so you must obtain the current mute status and then send the discrete (MUON/MUOFF) command.
I would like to do all this under one action. Unfortunately, when I attempt to fetch the mute status using TCP.WriteLn the result is not available in {LastResult} or {1} until the action has completed all commands within the respective action.
Is there any way around this as I would like to avoid multiple actions to perform one function.
Thanks

Let us see what you've got so far.
Does the receiver send out events, or some update messages when the volume or mute status changes?

Hi hpooni,
If you're not yet sure how to post the XML for your command, see: http://voxcommando.com/mediawiki/index.php?title=XML_on_the_forum#Posting_Your_Code_to_the_Forum
thx

Following contains the connection to my denon receiver.

Following contains a simple mute status action with result popup.

The denon receiver definitely returns data as 'DenonAVR1' event gets logged in the history window with the expected response containing '{1} MUOFF\x0D'

I guess you didn't see this post?
You just need to copy and paste groups from the tree to the forum. It looks like you exported a group, then edited it and copied from there into the forum. This is not only more work for you, it won't work for us when someone tries to copy and paste back to our trees. If you choose to export a group as a file then you should attach that file to your post, rather than copying the xml from it.

It may be possible for me to modify the plugin to include a new action that queries for a value and then waits a set amount of time for a response which gets stored into LastResult. At the moment it is not possible and I can't say when I will get around to it, so it will be better if we can find a solution using the current plugin available.
Your Denon is responding with the information you want using an event when you query it for the volume, which is good. I was wondering if the Denon also generates that event whenever the mute status changes. In other words, after you have connected to it with the TCP client action, if you change the mute status on the Denon by some other means, such as a remote control, does it send an event without being asked? Probably not, but if it does it would make our lives a bit easier.
With the current event that you get back you need to have a command that responds to the event and stores the payload in a variable, or does some kind of logic based on the payload.
If I have done it properly, this command should display your response from the Denon.
<?xml version="1.0" encoding="utf-16"?>
<command id="355" name="denon mute event" enabled="true" alwaysOn="False" confirm="False" requiredConfidence="0" loop="False" loopDelay="0" loopMax="0" description="">
<action>
<cmdType>OSD.ShowText</cmdType>
<cmdString>{1}</cmdString>
<cmdRepeat>1</cmdRepeat>
</action>
<event>DenonAVR1</event>
</command>
I may try to create a similar solution for my Onkyo, and then you can just modify the protocol a bit to make it work with yours.
I'm not too sure why you need a toggle action. Usually the problm people face is that they only have toggle and they need a way to perform discrete mute on/off.

My bad about the incorrect code pasting. Will remember for next time.

I think this pretty much answers my question. I will implement a second action which resonds to the event generated by the mute status action, as you've suggested below.

It actually does generate events for remote key presses and you're right I could use that as trigger to toggle the mute but I was hoping to do the whole thing as one complete package.

Correct. I had already done this and it works but as I stated before I was hoping to do everything within one action.

Mainly for hard-button remote.

I think you mean one command, not one action. But my point is that you can store information that comes from the Denon as it is delivered and then it is ready for you whenever you need it. When you want to toggle the mute (for whatever reason ;)) you can do it all in one command very quickly without having to ask the Denon for the mute status because it will already be stored in a variable. The same would be true if you needed to know the volume for some reason. If I were going to write a custom plugin for the Denon, this is exactly how I would do it anyway. You just need to do some results.regex on the command that receives the DenonAVR1 event, so you can decide what to store, in which variable.
Mainly for hard-button remote.
I still don't understand. It's OK. I don't need to.
-
Ok I will experiment a bit and see if I can implement your suggestions.
Thanks for your help.
-
If you need help with the regex for the returned values let me know. I will need to see what kind of different messages you get from the Denon for volume, mute, and anything else that you think would be relevant.

Thanks. I'm actually trying to use the PY plugin and pass {1} and {LastEvent} as parameters to the python script file.
The action is PY.ExecFile C:\Utils\voxcommando\data\DenonStatus.py {1} {LastEvent}
The above is triggered successfully by DenonAVR1 event and following is captured in the history window.
PY.ExecFile:C:\Utils\voxcommando\data\DenonStatus.py&&MUOFF\x0D&&DenonAVR1
My question is, how do I retrieve the {1} and {LastEvent} values inside the script so I can process them? FYI, I'm using PY instead of regex directly as its more flexible and I may do some other processing in the script.
Thank again for your help.

It is fine to use python but you can certainly do what you want without it.
You are adding the data in the parameter where the filename is supposed to go, so that won't work.
You need to define a function in your file and load that file once using PY.ExecFile once (usually done using the VC.Loaded event) and then you send the data in a call to the function.
You can call the function and pass it parameters like this:
PY.ExecString myFunction({1},{LastEvent})
If you need specific help with this still, please post your code. P.S. version 2 of VC will allow you to get a response from the server in a new action Tcp.Client.Query

You're probably right but I like python and need the practice :)

Yeah I read this in the documentation but wasn't sure if I could pass parameters directly to the script file. I will implement using a function.

Thanks. I look forward to V2.
-
it is much better to define a function anyway.
Here is a little light reading that might help ;)

Agreed, using functions is a better approach.
Thanks for the reference material. Works well now. 8)

Hi hpooni. Would you please post whatever working XML you have for controlling Denon AVRs using the TCP plugin. I'm sure there are other users that would benefit from this. Thanks.
-
Yes please! I spent the majority of the night trying to work on this same issue.
