Show DENON AV reciever input in Text switch

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?

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

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

Show DENON AV reciever input in Text switch

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).

Code: Select all

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 :D.

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. :/

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

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!

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 :)

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? ;)

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.

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?

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.

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

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?

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.
