Hi @eliah, thanks for your comment!
The module looking for groups regularly is by design: there is unfortunately no event when groups changes therefore they are pulled every 5 seconds. The listeners are set only when groups have changed.

I checked on my mirror and cannot see a difference of CPU usage with or without the module enabled. How “bad” is the CPU hog on yours?

@tbouron,
In my case it seems that the script always consider that groups have changed, but that’s not true in fact. The log is full of repeating lines like that:

And as I said before, actually all speakers are paused so nothing is really playing.

@eliah That’s interesting, it would suggest that the group IDs are not consistent (as groups are cached by IDs) which obviously shouldn’t happen. I’m also wondering if targeting a random device on every scan has any implications on this (but it shouldn’t, at least I cannot reproduce this on my own network)

Would it possible for you to test a different version? I would like to see how it can be mitigated.

eliah

sure, I can test if you have any ideas why it is happening.

tbouron

Hi @eliah. Can you try the version on the branch fix/group-scan and tell me how it goes ?

You would just need to go into the MMM-Sonos folder and do:

git fetch && git checkout fix/group-scan

Thanks :)

Jas

@tbouron Beautiful module. How can I get the album art and Rooms that are stopped to also show up? What other info can I display?

Thanks

tbouron

Hi @Jas and thanks!

Both of these are not supported. The concept of the module was to have a Sonos now playing... module with minimalist design hence:

only vital information: title, artist, album (can be toggled), metadata: room, volume and track length (can be toggled)
no album artwork
show only rooms where music is playing, otherwise show nothing to avoid clutter

It would not be too hard to do all the above, but I don’t plan to do it anytime soon because of the concept.

Jas

@tbouron Got it! Thank you for the quick response. Looks great!

tbouron

@Jas No problem. Feel free to add an issue on GitHub. If enough people really want it and +1 the issue, I’ll consider doing it ;)

eliah

@tbouron It looks like the issue is now fixed, no constant updates anymore! Thank you. :)
Some more issues I noticed:

Value for song length minutes has no leading zero, so when a song’s length is 2:04 it shows 2:4.
If any of speakers are used directly by AirPlay, it shows (null) (null). Maybe it’s better to ignore AirPlay mode if no information is available for it?
Not sure if it is a bug of a module or Sonos library behind it, but for some reason the group names are sometimes become incorrect. For example, if I start a playlist on three speakers in the same group, first it shows something like “Kitchen+2” (and that’s correct), but after some time it becomes just “Kitchen” (same 3 speakers are playing).
And additionally, if more than one speaker is playing in the same group, each of them can have its own volume. In this case the single volume indicator that your module outputs to the screen becomes useless.
