Show DENON AV reciever input in Text switch

[dijkdj]

I want to read the output of my Denon reciever. This information is in an XML file under http://192.168.1.22/goform/formMainZone_MainZoneXml.xml
The line with information is

Code: Select all

<InputFuncSelect>
<value>Squeezebox</value>
</InputFuncSelect>

You can see that the choosen input is "Squeezebox". I want to show this value in a :"text" switch. Does someone has an example in LUA code?

[ThinkPad]

I would start by searching for some tutorials/projects where they parse XML with Lua. Or Bash... Or Python

[dijkdj]

A tutorial would not be bad If I can start with a few lines that do what I need, I can start adjusting

What I did is created a shell script which runs every 2 minutes and just basically greps some values from the xml and puts it in an text switch. This is a grep example:

Code: Select all

curl http://$DENONIP/goform/formMainZone_MainZoneXml.xml | grep -oP '(?<=<InputFuncSelect><value>).*(?=</value)'

Is is also possible to send actions to you receiver, for example like this:

Code: Select all

curl http://DENON_IP/MainZone/index.put.asp?cmd0=PutZone_OnOff%2FON

@Mooseknuckle Can you do a step by step for noobs please! I can create the script, but run it every two minutes and add it to a text switch is another thing.

If I run this scrip manually I get the last selected source, like AUX, and what I'm looking for is for its state, ON/OFF. So I can set rules based on Denon status.

Thanks.

I use the following script. It is based on the synology monitoring script found on the Domoticz wiki so credits to the creator of that script.
I basically put all the info from the xml file into a text file and the grep the info that I want and put it in a text switch but for the on/off status you can also use on/off switch.
Here is my script, lots of room for improvement but atm it works for me. You can add/change/remove depending on your wishes. I made one virtual light switch and 3 text switches for my version.
The short version, it does a ping. If the receiver is off, it sets the on/off switch to off. If it responds to the ping it will check if the receiver is on or standby. If it is standby, it will set the on/off switch to off. If it is on it will grep the info I want (On status, Volume level and Input selection).

Besides getting info into Domoticz you can also give your receiver commands based on triggers. Here are some examples:

Code: Select all

curl http://DENON_IP/MainZone/index.put.asp?cmd0=PutZone_OnOff%2FON # receiver on
curl http://DENON_IP/MainZone/index.put.asp?cmd0=PutSystem_OnStandby%2FSTANDBY # receiver standby

You can give more commands, information can be found here:
http://forum.kodi.tv/showthread.php?tid=162592
https://github.com/jtangelder/denon-remote (lots of info in the protocol.pdf)

For example, I made a scene in Domoticz for when I want a romantic dinner with my gf. It sets my Hue lights, it turns off the tv (if its on), turns on my receiver and set it to a favorite internet radio station at a predefined volume level .

I hope this will get you started.

@Monoseknuckle

I created the script, changed the Denon and Domoticz IPs and when I run it I get this errors and the text.txt file is empty :/

If i run from domoticz terminal: curl http://10.1.1.7/goform/formMainZone_MainZoneXml.xml > test.txt it works just great, in the script I don't know what's happening. :/

[Mooseknuckle]

Did you also change the IDX numbers into the numbers of your own switches?

[Morcegolas]

I forgot that! :/
Now that I change it reports:

I created 4 virtual switches, all the same way, on/off light switch. The Denon Switch that report the ON/OFF state off the receiver is working great, the other 3 ( Volume, Input and Status ) they all stay off, I have to change anything on the virtual switches?

Thanks for the big help!

[Mooseknuckle]

It's not going to work with 4 virtual on/off switchtes because you can't put text info in that. You have to create 1 virtual switch for the on/off status. For the other 3 that get the info from the xml file you have to choose "text" as virtual sensor and not "switch" when you create them. I should have explained this better in my first post

[Morcegolas]

Thanks, it's working great now! The only thing that it's still missing in my configuration is to run the script automatic every 2 minutes, can you help me doing that?

[Mooseknuckle]

To run the script every 2 minutes you open crontab (crontab -e) and add the following line:

Code: Select all

*/2 * * * * /home/pi/domoticz/scripts/denon.sh

Maybe you have to adjust the path and name of the script, then it should work.

[Morcegolas]

Everything 100% now, thanks once again.

Just one question, isn't possible to change the text icons on domoticz so they can match a sound icon for exemple?

[Mooseknuckle]

Maybe it is but I haven't done that. You can check here http://www.domoticz.com/wiki/Custom_ico ... binterface for more info.

[dijkdj]

YOU ARE A HERO. WOW! Works perfectly!

Now I will have a look how to only update a sensor if the value is changed, that helps keeping the log clean.

[pepeEL]

Maybe someone who knows write plug into domoticz to handle Reciver Denon AVR as works KODI in Domoticz?

[Panda]

Thank you for the script, strange thing is that my Denon Avr-x1200 displays 44db but the script and xml page returns 36, what could cause this?

Would be cool to have all this info into one switch.

Edit: When I put it on 40db it will show 40db but when I put it higher then 40db it will go down, so 40.5 gives me 39.5 strange..., what I also noticed is that when you changed input name like I did, e.g. Mac Mini it will return http error bad request because the input name contains a space. Anyway to fix this to send space to domoticz?

[Egregius]

That's 80 - value because 80 is the max volume of the Denon interface.

I use a webpage for this:

There are 2 modes you can use for Volume control with Denon. The first one is sound level - between 0 and 80 and the other one is attenuation, so muting. With the first one, you set the level to (ie. 30) and the value you set is 30-80, meaning you mute it by -50. With db, it is even more visible as you are specifying directly, you are attenuating by ie. 30db. I hope, I made myself clear.

[pepeEL]

Is anuone who can create plugin/support for Domoticz to support control Denon AV as is created in Domoticz now plugin for KODI media...
How you use this script for control DENON AV by Domoticz ? Sorry for my english and i am begginer.
