Accidentally upgraded to S2. Need to downgrade my Sonos ones to be compatible with S1 controller. Reset and they are at flashing green, but S1 controller add device option is greyed out. So mad! Need help!

Very curious where you might have read that downgrading is possible - I’ve always read it is not possible. Do you have a link?

Is this process reversible?

While we don’t recommend downgrading your products to S1 after updating to S2, it is possible to downgrade by resetting the S2 products to their factory settings and adding them to an existing S1 system. An existing Sonos product running S1 software is required to downgrade an S2 product back to S1. Note that all settings and preferences will be lost when downgrading a product from S2 to S1.

Set up separate S1 and S2 Sonos systems

I’m sorry to complain BUT I’m going to.

I had 6 S1’s and 1 Play:5 running Controller 1, everything was fine we loved our whole house Sonos system. Then the upgrade notice came and my wife pressed it. S1’s are fine bricked the Play:5. I’ve tried going back to Controller 1 with partial success, still can’t get my play:5 to work. $500 shot to hell.

wouldn’t recommend Sonos ever. I have $2000 worth of equipment. I feel they owe me a Play:5, they made a dumb decision, if they thought I’d buy more compatible equipment, they’re nuts. Who knows when they might do this again. Bad marketing or dumb engineers, 3rd parties have figured out how to make S1 & S2 work with one app…..

Did you remove the Play:5 through the App when upgrading?, this will have factory reset it.

You will have lost your account on the Play:5 and everything will have moved over to S2.

I would be tempted to wire the Play:5 to your router and try to set up an S1 system with the S1 app from scratch, turn off ALL your other speakers first.

You may need to create another Sonos account, but that will just be temporary until you get everything back on S1.

I'm still on S1, still works exactly as I want and see no need to go to S2.

It's amazing how any user can allow upgrading, in my opinion there should be a Master User and only they can allow these upgrades.

I put a speaker on S2 for my Daughter purely so she didn't accidentally upgrade our whole house system.

According to all I have read rolling back the upgrade to S2 is not possible.

Who are you mad with?

Like the rest of us, probably with Sonos for failing to adequately support S1, providing instructions for a downgrade that doesn’t work, for installing upgrades without notice, and for providing erroneous information. Does that help?

Exactly what happened to my system except for the wife part. While installing a new S2 device, all my units were upgraded to S2 except my Play5. And the downgrade does not work. So now I’m in limbo. Really mad at Sonos.

I have also upgraded my one SL to S2 after my router went down. This SL was configured to a S1 controller and was functioning well together with the other S1 speakers. Now I cannot downgrade it to S1 again. It plays well on the S2 controller but when I try to downgrade it the S2 controller cannot find the one SL. Any Ideas what I can do?

Once a Sonos OneSL is running on S2 there is no way to downgrade back to S1.
It just still works for Sonos One (without SL).
