Logitech Media Server

I do use 2 PiCoreplayers (and have added them to wiki as compatible). PiCoreplayer is using squeezelite under-the-hood)
The only thing not working is the remote control, but that hasn't been working for a long time.

Does your player function from within domoticz? Show 'now-playing' title?

Sorry been absent for some days. Domoticz was not playing nice to me. Yes, I do see some titles in the log.

Code: Select all

If you look at the devices table, can you see any switches under the LMS hardware? Anything strange with those?

Does it look similar?

[EdwinK]

Nope, no switches at all.

But on the hardware tab:

This is all.

[Nautilus]

Just to double-check - you've allowed new devices?

[EdwinK]

Yup.

Even done with disabling and re-enabling the hardware while Domoticz was looking for new switches

Then I guess the only option is to go back here: https://github.com/domoticz/domoticz/bl ... .cpp#L1502 and try to determine the reason for the error message to see if it would help in finding the root cause for the problems.

If I understand it correctly, the sql query returns as empty which then throws the error in question. Even though it refers to "switch type" I guess the reason for an empty query would be the fact that it is missing from the db (Name == '%q' -> does not exist). If you check the database, can you see anything there related to this hardware, for example in this DeviceStatus table? In any case, I'm afraid someone who has worked with this plugin would be needed to help you here...

[EdwinK]

Yes... Well.. I guess I just have be patient then. I'm not really confident enough to work in the database.

Possible bug - deleted devices continue to be queried against LMS.

I was seeing entries in LMS logs saying something like:

Code: Select all

[18-10-12 14:58:02.5874] Slim::Web::JSONRPC::requestMethod (455) 00:11:22:33:44:55: request not dispatchable!

(edited the MAC address)
This means that LMS was not able to find the requested player.
In my case this is because those particular players no longer exist.
So - I used Domoticz web UI to delete the likely candidates (UI does not show MAC address) - via
Setup/Devices/checkbox on left/Delete at top of column
(incidentally the checkbox does not appear on my Chrome on Windows 10 - but does in MS Edge)
Queries continued to be sent to LMS.
Restarted Domoticz and rebooted server (RPi) but queries still sent to LMS.
So - looks like the Logitech Media Server type hardware either has its own tables or is not seeing a "deleted" flag in the main tables.

I removed the LMS type Hardware - and the polling to LMS stopped.
I then added it back in again and it discovered the players attached to LMS and did not poll for the deleted devices any more ... so I suspect that deleting the hardware is what made the entries really disappear from the database.

Hi guys,

I am using the "SB audio alerts script" from here https://www.domoticz.com/wiki/Logitech_ ... ox_Players

Me too. At least, am really looking forward to. I already have the script in place, it is working, yeah. One limitation though, I am almost only using my LMS with Spotty for Spotify. And now the playlist is replaced by the chime and message, but the previously used Spotty playlist is not being resumed. Would this also be possible with the script?

[philchillbill]

... but the previously used Spotty playlist is not being resumed. Would this also be possible with the script?

I checked it just now with Spotty (I had actually never used Spotify before myself) and after playing an alert it continued just fine with the current song from the correct position in the song. The now-playing _path is just something like spotify://track:2kLI2XQQaRjj5Xo4zAlHZn and the script handles that fine.

Do you have a playlists folder defined? The problem is that in LMS you still need to have a playlists folder defined, even if you are not using local music files. This needs to be defined in your LMS settings through the web-interface settings --> basic settings --> playlists folder. This requirement is hard-coded into LMS - when I save the current playlist in order to restore it again after the alert, the JSON RPC underpinnings need to have a directory to save that file in. Add a directory name and you should be good to go !

Note: The wiki entry did actually mention that the playlists folder needs to be defined but it was mentioned towards the end after the scripts and was easily overlooked. I've edited the wiki and moved it up under setup process and it now also specifically mentions Spotty

[mschut]

Do you have a playlists folder defined? The problem is that in LMS you still need to have a playlists folder defined, even if you are not using local music files.

And of course, I remember reading that. However, I was thinking it should be something caused by the fact that the LMS and the Domoticz server are on 2 separate Pi's. Only to find out it does work properly now after only adding a playlist directory. Thanks a bunch. Starting to enjoy this feature now.

This succes leads me to my next question. I am using the first option (threading). However, if I use alerting on 1 device it works just fine. If I use 2 ("device1, device2"), the LMS server only shows the prechime name (and not the ttsfile name), and nothing is heard at all (also not the prechime). It does return nicely to the previous playlist though. What could be going wrong here?

[philchillbill]

Good to hear you solved the issue with the correct playlist resuming. The issue with listing multiple players is probably some kind of parsing error. To debug that, add the following lines to the perl script towards the very end:

Code: Select all

($players, $prechime, $ttsfile, $avol)=@ARGV;
@players=split(/,\s?/, $players);

becomes

Code: Select all

($players, $prechime, $ttsfile, $avol)=@ARGV;
@players=split(/,\s?/, $players);
print "Debug: @players\n$prechime\n$ttsfile\n$avol\n";

Go to the directory containing the perl script and run it directly from the command line (not via the bash script this time, as it will go to background and not display the debug info):

./sqalert.pl "livingroom, kitchen" Ring06.wav garageDoorOpen.mp3 60

but using the names of two of your players, your chime file, and your tts file. What gets printed?

[mschut]

Hmm (thanks again for the quick response). However, it doesn't print anything, not with 2 devices, not with one...

I am on a Pi, connected through a SSH terminal.

[mschut]

I also quickly tried the other script option (with sync). With one device this is working too, with more, same behaviour. I assume it has something to do with the " character.

[philchillbill]

Are you sure you ran the Perl script directly and not the bash? With the bash it’s logical that output is suppressed but the Perl is printing directly to your screen...

Ok, sharp this time. Direct perl

perl ./squeezealert.pl "Aanrecht, Woon" chimes.wav Door.mp3 50

results in:

Code: Select all

Debug: Aanrecht Woon
chimes.wav
Door.mp3
50

And it works as supposed.

Next, when I perform the script in Domoticz (scripts://sqalert.sh "Aanrecht, Woon" chimes.wav Door.mp3 50), the LMS only shows the prechime name, not the alert, and nothing is heard. The playlist is nicely returned though.

[philchillbill]

What does your sqalert.sh look like? How many parameters get passed to the Perl (the $1 $2 $3 etc)?

After deleting. reinstalling, deleting and reinstalling again, suddenly the LMS is back in domoticz. So, now I'm making a backup of this setting to be sure it is there to stay ")

[philchillbill]

I've been playing around with sending json to the LMS server via the Domoticz UI instead of via JSON RPC calls to the LMS URL directly. I see that commands like:

Code: Select all

/json.htm?type=command&param=lmsmediacommand&idx=562&action=VolumeDown

work, as do VolumeUp, Forward, Rewind, etc. Looking in the CPP source file, I see that there's also an action 'SetVolume' but I've no idea how to specify the value for that. Same is true of 'PlayPlaylist'. Can somebody give an example (non-LUA) of how to define these values from a json URL?

[pvm]

Now I get this error:

2018-09-07 23:20:11.091 Logitech Media Server: (piCorePlayerHSK)'
2018-09-07 23:20:11.066 Status: Logitech Media Server: 1 connected player(s) found.
2018-09-07 23:20:11.093 Error: EventSystem: Could not determine switch type for event device piCorePlayerHSK

How to fix?

EdwinK, I think I've found the issue. I reinstalled my complete domoticz setup and after a couple of days I got the same error, complaining about 'somename' .

• My player, in the logitech media server hardware screen, was called 'somename')
• My player, in the 'switch' screen was called, 'somenameLMS'.

When I changed the device name (in switch screen) back to 'somename' the error disappeared.
