Great work mate!

I don't understand why the status of the receiver must be published to domoticz.
Why not just use a page to control it?

[simon_rb]

I have it in domoticz so I can control it via Siri

*There is a plugin that does this but that crashed my homebridge when the amp was turned off at the wall and couldn't be reached from the homebridge plugin.

Don't know how pretty this is but it works
This updates the sliders and only updates the switch if its different...

Code: Select all

commandArray = {}
function execute(command)
        -- returns success, error code, output.
    local f = io.popen(command..' 2>&1 && echo " $?"')
    local output = f:read"*a"
    return output
end

--read xml and remove value strings
--<MasterVolume><value>-60.0</value></MasterVolume> becomes -60.0
function get(data,name)
    data = data:match("<"..name..">(.-)</"..name..">")
    data = data:gsub("<value>", "")
    data = data:gsub("</value>", "")
    return data
end

vol_tv = execute('curl --url "http://192.168.1.12/goform/formMainZone_MainZoneXml.xml" &')

--get volume of TV and update volume switch in Domoticz if it differs
local vol_tv = get(vol_tv,"MasterVolume")
local vol_domo = otherdevices_svalues['Denon Volume']
print(vol_tv)
vol_tv = tonumber(vol_tv) + 80
print(vol_tv)
if otherdevices['Denon Volume'] ~= 'Off' then
    --if (vol_domo ~= vol_tv) then
difference = math.abs(vol_domo - vol_tv)
if difference > 1 then
        --commandArray['UpdateDevice'] = otherdevices_idx['Denon Volume'] ..' |2|' .. vol_tv
os.execute('curl -s "http://192.168.1.26:8080/json.htm?type=command&param=switchlight&idx=284&switchcmd=Set%20Level&level='..vol_tv..'" &')

    end
end

return commandArray

OK so this is brilliant, and I've been at this for a long time not wanting to go into .sh but remain pure Lua.
Mymissing piece was getting the correct value back from the xml stripping all the stuff you don't want. The rest of my script worked apparently, but getting values like SAT</ and such got me crazy.

This Volume example works like a charm, and I have also created this for my Selector Switch with SOURCES on the Amp. After 1 minute, the Selector Switch is set to the current mode when you for example use the remote to switch on the Amp itself, extracting the <InputFuncSelectMain><value>SAT</value> as SAT in this case. If the Selector Switch is not matching that, the script will set it correctly.

I wanted to move on to the Surround mode, which is an easy copy over from the sources script, but searching for: <selectSurround><value>DOLBY DIGITAL </value> gives me an additional SPACE before the </value> and this is why it cannot be compared to the Levels named on the Selector Switch exactly it seems. Any idea to strip SPACE character before the </value> but not entirely as there is a space between DOLBY and DIGITAL too?

Cheers,

Ray

Hi All,

Just wondering if it is possible to modify the range of the dummy switch - slider object.

If so I can match the range displayed on the AV receiver perfectly with the Domoticz object, in addition autoswitch to absolute <> relative which I can read from the actual configuration.

Next will be to implement the Source Select and synchronization to the scripts I posted

Thanks

I use absolute for my amp and use the 100 (0-99) slider within Domoticz. I don't believe you can change it within Domoticz as such. It depends on the dummy switch you create. For me the 100 dummy is enough as I didn't like .5 volumes anyways - would bug me if it was at 65.5 for example lol.

I've written the script which I will share soon after cleaning it up a bit.
I'm working on the Surround Setting Selector Switch too, but ran into a problem I posted just above.

OK, that was easier than I thought cleaning it up. Here's my script for getting the Selector Switch for Marantz SOURCE in sync.

Hi guys,

EDIT: Problem solved, keeping this post for future guidance!

First off I want to thank you for all the hard work you've put into this. I've read the entire thread a few times, both before installing and now again to get help. I'm a beginner in unix and I don't do code so I might have made some rookie mistake, feel free to point and laugh if so.

So here's the setup:
*Denon AVR-4200X that I control through HTTP
*Domoticz running on an RPi

When I run the script with the amp turned on it mutes it. I've added the http://IP/MainZone/index.put.asp?cmd0=P ... Mute%2Foff to the On Action and the opposite (On) for the Off Action for the Volume switch according to the instruction.
Here's what I get when I run the script (the not found's are empty lines as someone previously pointed out):

No settings are updated except for the Text Switch that get's the "No denon detected" tag. It seems as the defaulting function is not running properly. that's really all I can guess.

Edit:
Forgot to add the dummy device list and the settings in the script for comparison ->

denon domoticz.png (89.95 KiB) Viewed 14566 times

Edit2: I've been doing another tutorial for something completely different and they suggested that you execute the script with sudo ./nameofscript.sh. As I did that for the Denon script it gave me a different error and the denon.mainzone.settings and denon.net.settings files were finally created! One step forward!
The error I got was "row 149: bc: command does not exist" but I was able to solve it by installing bc (sudo apt-get install bc). It finally seem to work! The volume is updated and next step for me will be setting the inputs!

[Vendrom]

Firstoff -> Thank you to everybody creating awesome things, and trixwood for denon.sh

Maybe somebody can help me out, because i cant seem to find the solution.

i have an RPI, denon avr-x2000, and the denon.sh script in my /home/pi/domoticz/scripts location.
i've configured a few switches:



also configured these settings in denon.sh

# Settings
DOMO_IP="domo" # Domoticz IP Address
DOMO_PORT="80" # Domoticz Port
DENONIP="denon" # Denon IP Address
DENON_IDX="79" # On/Off (Switch) IDX *1
DENON_STATUS_IDX="81" # Status (Text) IDX
DENON_MUTE_IDX="80" # Absolute Volume (Slider) IDX (same as Absolute Volume)
DENON_VOL_REL_IDX="82" # Relative Volume (Sound Volume) IDX
DENON_VOL_ABS_IDX="80" # Absolute Volume (Slider) IDX

but as you can see on the screenshot, i get these outputs on my switches:



202% or 25.0% on my denon.
the denon is using absolute, which i can also see on the webpage from "http://denon/goform/formMainZone_MainZoneXml.xml

<VolumeDisplay>
<value>Absolute</value>
</VolumeDisplay>

and also retrieve "absolute" from using code from denon.sh
"sed -n -e 's/.*\<VolumeDisplay><value>\(.*\)<\/value>.*/\1/p' denon.mainzone.settings"

so i am lost, how can i receive the correct (25.0) output on my virtual device (IDX=80)

[trixwood]

I never tested the final script it with absolute so look into denon.sh at this piece of code

Code: Select all

      if [ "$AVvolume" == "--" ] ; then
          AVvolume="0"
          AVisvolumerelative="Infinity"
     fi
   
    if [ "$AVisvolumerelative" == "Relative" ] ; then
      #echo "Volume: Relative"
      AVvolumeAbs=$(echo "80.5 + $AVvolume" | bc) 
      AVvolumeRel=$AVvolume
    else
      #echo "Volume: Absolute"
      AVvolumeRel=$(echo "80.5 - $AVvolume" | bc) 
      AVvolumeAbs=$AVvolume
    fi

    # exterminate, exterminate, convert... convert...
    AVvolumeAbs=$((${AVvolumeAbs//\./}/10))

    # decode old value
    AVvolumeoldAbs=$(($(curl -s "http://$DOMO_IP:$DOMO_PORT/json.htm?type=devices&rid=$DENON_VOL_ABS_IDX" | grep Data | grep -Eo '[0-9]{1,4}')+1))
 
    #echo "Volume: $AVvolumeRel db $AVvolumeAbs ($AVvolumeoldAbs)" 

And put in a lot of

Code: Select all

echo "Volume: $AVvolumeRel db $AVvolumeAbs"

and run it in the terminal (not from domoticz) and check the output if its correct...

and in the lua code for the device event you have to look at

Code: Select all

SendLevel = NewLevel - 79.5

since that is always relative...

[pvklink]

This script works great.
The only thing i dont understand is the code:
SendLevel = NewLevel - 80 --79.5
I think i can change this by SendLevel = NewLevel
I will try it out.. rest is working great with my denon!
My wife didnt understand how to operate the reciever and now she can with the domoticz app!

Hey guys!

First of all, thanks for all the hard work. It's great to see so many people spending their free time to build all of this.
I was wondering if anyone made any further progress with this project. I've followed the wiki page (https://www.domoticz.com/wiki/Denon) and all of it seems to work fine. I still have the 'issue' that was discussed earlier with the volume changes back to 55 when you change it. I've read the topic but i'm not sure how i'm able to fix it because of the amounts of code. Is it possible to update the wiki page or something?

[Leemur]

Hi
Did you know how create virtual device in Domoticz to set for Zone 1 and other to Zone 2 SLEEP TIME in DENON AVR-X2100W ?

Yes with http you can, simply add in the URL (or in the message body if you're using POST) &ZoneName=ZONE2
You can also set MAINZONE to this value (&ZoneName=MAINZONE) to explicitely say that you are working on zone 1 (usefull if you use a parameter to set the zone)

For instance if you want to set MPLAY source for zone 2:

Code: Select all

http://DENONIP/MainZone/index.put.asp?cmd0=PutZone_InputFunction/MPLAY&ZoneName=ZONE2

I guess it works the same for the sleep time

[landi]

Hello there,

First of all thanks for the nice work. I'm using event script and bash script as described here: https://www.domoticz.com/wiki/Denon , with my Denon AVR 1100X however there is one thing that I don't get...

When you switch off device using "DENON_SOURCE" switch from defined source - for example "DVD" to 'Off' and you would like to turn in on again to the same source ie. "DVD" - it's won't work. So for example if your Denon was switched off when being on 'dvd' state, it works when you switch it back to 'AUX1' but it doesn't when you try to switch to the last input source (dvd).
The workaround is to switch it to another state before "off" and then switch to the different state to be "on" - then it works.

Anyone had this problem ? and anyone have a patch for this ?

[MichaelvK]

Hi, I have found the script very useful, but was missing source names for the other sources.
I am using an AVR2300W, which has some extra sources.

Because it has to be the very exact names, I searched and found an RS232 coding with Source names:

PHONO
CD
TUNER
DVD
BD
TV
SAT/CBL
DVR
GAME
V.AUX
DOCK
HDRADIO (AVR-3311-CI model Only)
IPOD

hi,
great stuff.

i have an denon avr x2400h and it won't work.
can somebody tell me what commands i have to use?
when i try to check some codes with firefox i only get Error 403: Forbidden Access Forbidden.
and where i have to put the xml file exactly?

This wont work with the 2016 onwards AVR's as Denon have stopped access to the Web Control API. I have just updated to a X3400 from an X2000 so its broken for me also. No sure how to fix it.

The web control API is still there, but has been moved to port 8080. See https://github.com/scarface-4711/denona ... -354880648

I've successfully used http://<IP>:8080/goform/formiPhoneAppPower.xml?1+PowerStandby on my X4400H as the plugin (which uses Telnet) loses sync with the status of the receiver.
