S1 Creating New Account Issue

Any privacy or VPN stuff on the phone?

Is the speaker still registered to the old account?

No privacy or VPN stuff on the phone. I have factory reset the speaker.  It shows up on my S2 phone with a pop up about not being able to add it (which is fine as I’m creating a separate S1 ecosystem).

Why not just use your existing Sonos account details for the S1 system?

It wants to downgrade my existing S2 system to S1. I want my Play 5 isolated.

Reset the S1 app, then select the option to create new system when you reopen S1 app.

The Play:5 may need to be rebooted or factory reset again to allow setup, if the led is not flashing green.

If you still have issues, power down your S2 system when you attempt the S1 setup.

I’ve not attempted this, but two suggestions:

1. Use a different email address, on the chance it recognizes one is already in use. No idea if Sonos actually checks this, but worth a shot.
2. unplug all your S2 devices while setting up this S1 system (once you can set up the account, that is), it should stop nagging you (somewhat) about downgrading.

Honestly, I don’t get the ‘isolated’ requirement. I’ve got rooms on my system (S2) which I never group with certain other rooms, in my mind they’re ‘isolated’, but still on the single controller. The only time I’d ‘force’ a different OS is if I still had an S1 only device. 

I tried two different alternative email addresses, no luck. I’m wondering if I should try with the Play 5 hooked to an Ethernet cable?

Certainly wouldn’t hurt. Or calling Sonos Support to discuss it. They might be better than this public forum.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Update - pushed volume up while green light was flashing, heard a tone and now I have the flashlight yellow light.

S1 has not discovered the speaker. Also haven’t created an account. Will try that next.

Connecting by ethernet is normally the quickest solution for initial setup, especially for older devices.

And, just to drive this point to a ridiculous extent, if the device had been previously set up on S2, it won’t be ‘found’ by the S1 controller, you’d need to follow this FAQ. 

You can tell if the device is alive at least by connecting via Ethernet and then running my iOS app (see profile). It will find all devices on the network, even if not configured for accounts, even straight out of the box. This would at least verify the basics of life for it.

Read the information in the link below. There are several that may help.

However, I’m not understanding what you mean by “isolate”? As has been mentioned the speaker can be set to the same S2 with its own room name and not used until ready. Also downgrading a speaker to S1 means no future updates to latest features. I’m trying to understand why one would downgrade a speaker to S1 as from your profile all Sonos are S2 compatible. Running S1 and S2 systems do have downsides as mentioned in the link provided above.

This worked! Created an account and set up was a breeze!

Happy to hear that worked out for you.
