Sonos Bandwidth Usage When Not In Use

That’s odd, as my router only reports 12mb (or thereabouts) upload for each of my Sonos devices in a full 24 hour period and I’ve been using some of these speakers and checking for Sonos updates… and speakers I haven’t used in the past 24 hours have only downloaded 5mb or thereabouts in the same 24 hour period … nothing like the kind of data totals you mention in your post. Screenshot attached.

My guess is that the reports are indicating data being transferred not to the outside world, but between speakers.
 

Since most devices tend not to intercommunicate like Sonos does, it would make sense to me that they ‘appear’ to be uploading a lot of data, when instead they’re merely communicating with themselves, and the report interprets that as outbound traffic. 

On the other hand the quoted data rates could be explained by someone having muted a stream, rather than pausing it. 

@AK-79 .  Given your beliefs, I really think you should sell your Sonos gear. 

I have lost track of the number of reasons given on here for why Sonos are about to crash and burn, over the last 10 years.

Here is an interesting thread from Reddit

https://www.reddit.com/r/sonos/comments/ercm8v/sonos_using_800gb_in_a_month/

Thanks for those with constructive feedback. I only have one Sonos device and there are no paused streams or services in progress.

I actually discovered this by checking bandwidth usage late at night to check my son wasn’t gaming late, that’s when I saw the sonos drawing this data as the only and highest usage device on my network.

I agree, I think I’m at the end of my Sonos journey, having to do a factory reset it the other week as I changed wifi networks, as it wouldn’t let me simply switch networks via the app like I was prompted too, then having to install all services again and setup the dynamic sound which failed…. Yeah at the end.

Sonos One (white, with sort of an Alexa built in, but more like a gimmick Alexa) for sale £50 anyone?? 

You never needed to reset. You could have just temporarily wired the speaker and changed the WiFi credentials that way.

On the original topic, I have about 20 Sonos devices on the network at present. I can see from switch LEDs when there’s streaming traffic. With the entire system idle all I see is the occasional maintenance packet being exchanged between the units.

Im sure I could plug it in to the router and change networks etc but it’s in the ceiling https://ibb.co/CHjTV4P and a pain to get down off the bracket!  Just kinda expect this stuff to work.

As I say, one Sonos device, idle with nothing streaming or paused, 1GB per hour! 

This is local, not Internet traffic. You have started from a misinterpretation of the situation and ended up at bitcoin mining. Heaven preserve us.

Yep is external, am monitoring this via my ISP.  I’ve explained this further up the thread.

Unless you can 100% rule it out because your a  developer for Sonos then who knows what they’re using redundant CPU capacity for, was more a provoking statement than a conclusion.

Our "Breakfast Bar R” (a Sonos One gen2) speaker has been monitored since I posted above and it’s upload/download data is still far less than than anything you mention - unless Sonos are somehow also conspiring with our router manufacturer too, which I very much doubt? 

The router monitors all our connected network devices, showing both upload/download data, on a per device basis, based on MAC Address ...and that speaker is showing as uploading 8.34mb and downloading 3.4mb of data within the past 24 hours. Compare that to my earlier printout attached to my other post above some 16 hours ago.

So my thoughts are you are ‘likely’ measuring something incorrectly here or something else is awry with your particular setup. I don’t believe our router, is going to be that far out on its results and all the inactive Sonos devices are showing similar upload/download results.

Here is the print-out attached relating to that speaker.

Do you think as this is Alexa enabled it’s transmitting sound data picked up during the night, passing cars, people, maybe even the dog?

So it’s an upload at between 89kbs and 500kbs?

I’d start by looking at where the upload traffic is going, once you have that you have a better idea of where to place the blame.

If you disable Alexa for a period of time you’ll find out.
