Thanks for these Lua scripts, it's about time I rolled up my sleeves and did some real work integrating Domoticz and these look like a great start :)
If you are still looking for an alternative to polling MPD on a regular basis, then perhaps the MPC IDLE command will help.

If you update to the latest beta it should create the additional devices.
Thanks for that @Dnpwwo - I was pulling my hair out trying to work out why the latest plugin version didn't behave as expected. I upgraded to latest beta and it worked a treat

cd ~/domoticz
./updatebeta

Now running ...

To make it easier find the latest version, and to track issues, I have copied this 2.5.4 version in github at

Permalink to latest working version: https://github.com/artmg/domoticz-denon-marantz/blob/master/DenonMarantz.py

We can keep tabs on showstoppers and nice to have's in the repo's issues ...

Thanks for that @Dnpwwo - in my initial tests this version does suppress creation of devices for non existent zones, but in my case it also failed to create the main zone device selector. I'll take a look into the new code in the next day or so to see if I can figure it out. Cheers

So I found a candidate for python service discovery, python-zeroconf at https://github.com/jstasiak/python-zeroconf/ which still appears actively maintained, is packaged in python and has a debian package in unstable

However, as well as wanting to use Autodiscovery for clients whilst the plugin is ...

@Dnpwwo,

I am really impressed with the work you have already done on this plugin, and I think you've already got much of the functionality in there (or as you say, on the way). Once you release the next version, I can document it on the wiki and try to keep tabs on feedback we get. If I could ...

Where did you get the right list that the AVR recognizes? I took my list from the GUI of the AVR (by browsing to the IP address), but somehow the selector switch is not being updated.
Truly definitive list of sources, I guess, would be to find your particular AVR model in one of the official Denon ...

Hi,

I'm still quite new to the Domoticz ecosystem, but I am looking to work on a plugin for devices for a particular service (in this case the synchronised audio distribution service Snapcast). Like many modern networked audio devices, these servers and clients make themselves known across a local ...

Yeah, I understand your concerns, woodtrix - I have met problems with the "only one concurrent telnet session" limitation of Denons before. However I have found the current Python Plugin performs surprisingly well in my setup. I'd rather move forward by following the vendor documented telnet ...

With Marantz NR 1504 the plugin works well:
Power On / Off switch
select output for Main Zone
Set Main Volume
no contention on connections from Marantz Android App
read changes to above when switched elsewhere (remote / android app / AVR web UI) within a second or so

You need to take care to ...

The Denon & Marantz Company have sensibly chosen to use the same basic AVR Control Protocol across most of their products.

I am starting this thread to draw together knowledge and code to work towards a generic " DenonMarantz.py " plugin . Note that this intends to use the (single-user) telnet ...
