Hi, I have just purchased an Arc and a Sub and have a couple of questions.

  • Does Sonos products work without an internet connection?
  • What data is sent out by my Sonos equipment (and to who/where does it end up)

For security reasons I switch off internet access for all devices which are not essential, eg, the television (I used AppleTV instead), my printer, etc. So these devices have wifi access but no internet. I tried doing that with my Sonos system but found some unusual behaviour. First, the sub stopped working and only came back when I restored internet access, and second, I cannot use Trueplay when internet access is off - why? Why on earth is internet access required for local functions? 

I am guessing this is a bug? Surely the system should operate completely without internet access? What happens if Sonos goes bust? I am considering returning my equipment but am hoping this is a bug. (Will Sonos see this? If not what are the support options to get an official response?)

Thanks in advance for any help,

A worried new Sonos user.

You will need an internet connection to set up the system, for registration, updates and logging into your account. 
Once done you will be able to use the system without internet for tv source via hdmi earc cable connection, for streaming from your local music library, for bluetooth sources with compatible Sonos devices, for downloaded content via Airplay to Sonos and for input from Sonos devices analogue inputs. 
 

All streaming services like Sonos Radio and others will need an internet connection. 
 

As far as I know the data over internet is sent to Sonos and partially to connected streaming services and voice assistant services (Amazon Alexa and Google Assistant).
