This problem drove me nuts.  My solution, I created a totally different email account that had nothing to do with sonos.  That was the key to getting my Move to downgrade to S1.

I believe my email that I had used to register all my current sonos S1 products causes some Software bug to surface in the process of downgrading.   Using a totally unknown email (to sonos) made the downgrade finally complete.

Once downgraded I added the Move to my existing setup.

So probably something to do with the Sonos Boost needing an update then - Oh well, I guess all’s well that ends well.

Definitely don’t waste your time calling them. I spent over an hour on hold today just to be told that it’s coming back in a future update to the app but at the moment there’s nothing that can be done.  Trust me, I push them because I have equipment that I can’t use

Makes sense @Ken_Griffiths 

I called the support but there was nothing they could do. However they were aware of the issue and the supporter I talked to promised the feature will return to S2 app. She was expecting a couple of weeks, which would be great! So im gonna keep an eye out for the next S2 update. 

Yes same for me. Pass some hours to downgrade my Move to S1 ans the only thing working is to use a new account …

Rbasil,

Thanks for your post!  I was adding another used Play:1 and needed to downgrade it.  I spent several hours today with no progress.  I received all the same error messages posted above.  Your simple solution was exactly what I needed. 

I used a different email address that I rarely use to create a “dummy” Sonos account. I started the downgrade process and it sailed right through it without issue.  

Thank you so much for posting your solution.  I generally don’t post or comment, but your post deserved it. 

Hi Ken,

No it wasn't, I turned it off on my first attempt to add the Move last weekend as I know its on.
I forgot today as I was excited on receiving my Port :)

It’s standard functionality on the NetGear Nighthawk routers (RAX200), MAC address blocking (ips can change), if your names not on the list you ain't getting in.

The BRIDGE is the device that can not be moved to S2. The BOOST easily runs it. 

Thanks Ken, much appreciated.

I have begrudgingly bit the bullet and ordered a Port.
I am going to move to S2 completely.
I now only have a ZonePlayer connected to my home cinema downstairs as I just sold the rest of my kit (3 rooms) in order to upgrade at some point in the future. (Thats why i bought a Move).

I didn't want to upgrade yet, but feel it will be easier in the long run, and a little forced to.

Hopefully my Boost can be configured easily in the upgrade, as I have seen a few posts about them not moving onto S2………..fingers crossed

Rbasil, THANK YOU. I had the same problem for hours of troubleshooting while downgrading a Beam *Gen1 , and after creating a new account with a different email address, something other than my primary Sonos email address/login, everything downgraded smoothly and the Beam is now on S1. 

Good idea. No luck unfortunately. Cannot set up the device in s1 until it's been downgraded to be used for s1. Move comes packaged as an S2 product only. Have tried resetting, and reinstalling S2 app. Still cannot get Move downgraded.  Spent a bunch of time on the phone with Support. Still no luck. I'm at a loss

Try powering down all S2 products except the MOVE.

There’s no indication that the downgrade to S1 will be in the new Sonos App soon @RyanRJ, other than it was mentioned that the feature will be added at some stage - it could be days, weeks, or even months, I guess.

It’s why I suggested you get in touch with Sonos Support now, as they may have tools that can perhaps assist you to get the Move running on your S1 setup. Here’s the link to call them:

https://support.sonos.com/s/contact

Thank you for the link Ken - very helpfull! :) 

I’m refering to the issue highlighted here: https://support.sonos.com/da-dk/article/downgrade-a-sonos-product-to-s1 that it is currently not possible to downgrade a product in version 80.0. (Yes I have a Move Gen. 1)

This means that I have a speaker that I can’t connect with the rest of my setup. I think that is a critical feature - to sync music between the speakers. As SONOS describes on this page, I should be able to use move gen. 1 on the S1 app/setup. https://support.sonos.com/da-dk/article/sonos-app-version-compatibility 

So when is this feature back, so that me and many others again can link our speakers in the same setup?

Not sure about the issue you mention, but there is a roadmap here…

https://support.sonos.com/en-us/article/the-new-sonos-app-and-future-feature-updates

Assuming you are referring to a Move (gen1) and not the Move (gen2) that you’ve purchased recently, I think in your case you are probably best to contact Sonos support to get the Move onto S1. Otherwise you might have to wait some time, or you can maybe return it, whichever is perhaps easier for you. 

I have the same issue. I have a S1 setup and don’t want to upgrade. I just bought a MOVE because I know that it is S1 compatible. But can’t downgrade in S2 app, so can’t really use the product right now. 

Have anyone asked SONOS for a roadmap or prioritized list of fixing all these issues? 

Thank you

No. The normal way is to reset the device and with a S2 app you can then choose to downgrade (after which the S1 can pick it up).

But… in the latest 80.x version the downgrade option is (temporarily) removed. And when trying with the older S2 16.1 version, it detect it’s not the latest and asks you to upgrade the app first before downgrading a device (which is pointless because the latest S2 app is missing that feature).

The downgrade option will be back in the S2 v80 but who knows when… (you might need to wait a few months).

https://support.sonos.com/en/article/downgrade-a-sonos-product-to-s1

Sonos app version 80.0
The ability to downgrade a Sonos product to S1 is temporarily unavailable, but will return in a future update.

I’m looking to downgrade and apparently they just removed the The option to downgrade in the app. Is there anyway to do it?

Hi,

I am having same problem downgrading my new Move.
I have spent 2 days blocked from downgrading just going round in circles and can't call support until tomorrow.
I do not have any other S2 products. (2 older products using S1)

I have reset the Move and green light is flashing.
I have downloaded the S2 app (downloaded deleted and downloaded again).
I select the downgrade option
The S2 app can see the Move - next
I add my email to sign in and then it fails to connect saying i do not have internet connect…????
Im using my phone to search instructions so I clearly have. 

(I have tested my login works).

Des.

@FunkyStonker

I would maybe try this - setup the ‘Move’ on your S2 App once again. It should update during the actual setup of the speaker. When setup is complete and registered, wait for one minute or so.

Now factory reset the ‘Move’ again - Note between your mentioned step-2 (powering off) and step-3 (powering on) ..you do need to wait 10 seconds before powering it back on with the join button pressed - you can let the join button go when you see the status LED flash Amber.. no need to wait till it flashes Green. It will switch to flashing Green after a few seconds anyway.

Now reset the Sonos App (from Settings/App Preferences) and then try the downgrade process once again and see if it then perhaps works for you. 

It doesn’t mention anything here about having to sign in, see the Sonos support link below.

I have just quickly tested this, but didn’t get as far as actually downgrading anything (obviously), but the S2 App doesn’t ask for the user to sign in before searching/downgrading a device and once the FR device has been downgraded, you can just go onto delete the S2 App, that’s if not using …and then simply add the downgraded product (Move) to the S1 system via ‘Add Product’ in ‘Settings/System’ in the S1 App.

https://support.sonos.com/en-us/article/downgrade-a-sonos-product-from-s2-to-s1

Attached are screenshots (in order) of what I saw during the S2 downgrade process… (no sign-in was requested)… at least up until the point where the App searches/finds the factory reset device.

**UPDATE**  - Error 30

After trawling the forum I found a few things to try.

• Turned off all S1 products.
  Closed all apps.
  Opened and reset S2 app.
  Placed the Move next to the router.
  Router security opened up for all new devices to attach.

This time I was able to go through wizard a bit further.

I can now login
I was able to Setup a temp wifi for Move and join my current wifi.

Then the wizard said I needed to update the Move, this keeps failing and I'm stuck in a loop.
It fails with Error 30 and says to connect via cable to router…..

I am really disappointed with how difficult this process is.
I have always sung SONOS praises and advised people to buy into the products as they are great and just work with rock solid performance, but 2 days looking at this and still getting no where.

I bought a Play1 from a stranger but have been unable to connect it to my network. It appears to need to be downgraded since some of my equipment isn’t compatible with the S1. The S1 controller finds the item but asks me for an email but rejects the email with my account. Does this mean it’s looking for the seller’s email address? Is there any workaround? (This item has been factory reset already.)

try reseting the app,
go to settings>app preferences> look for app reset,
then setup your device again in s1 app
