S1 controller and downgrading software

When will the ability to downgrade software be restored to the S1 app?  I just purchased a Move speaker because it was supposed to be compatible with the S1 app and my older Sonos speakers, but in order to make it compatible, it needs a software downgrade.  The latest version of S1 removed this feature.  When will the app be updated to have that feature restored?  Thank you.

UPDATE:  I was able to resolve this thanks to others in the Sonos Community who reported that they were able to use an old Apple device (specifically, an iPhone 7) to download the old Sonos app to downgrade their speakers to S1.  As an Android user, it was a little challenging for me to find an iPhone 7, but I eventually got my hands on one, and it worked like a charm!  After logging into the Apple Store with my spouse’s Apple ID, I searched for the Sonos app.  The app appears in the Apple Store with the Sonos black logo, but once you download it, it switches to the old Sonos app with the gold-colored logo, which is the only version that is compatible with iPhone 7 operating software.  I then connected the app to my wifi network and the Move speaker and used the downgrade feature to downgrade the Move speaker’s firmware to S1.  I then used the S1 controller on my regular Android device to connect the Move speaker to the rest of my Sonos system.  The whole process took like 5 minutes (after spending weeks and weeks of researching and trying different things).  It’s a shame that Sonos cannot be more helpful by continuing to make the old app available while the glitches with the new app get worked out, but I am very grateful to the other people in this community for helping me figure this out.

Good news. As of this morning, August 7, 2024, Sonos released version 80.06.03 which now includes the S2 to S1 downgrade tool. Had a couple of quirky things happen, but it worked to downgrade three Sonos One Gen 2 speakers that I had purchased to expand my system (moved to a new home) and that have been sitting on a shelf the last few months.

I have a S1 system and, as many others here, bought a Move Gen 1 that came w S2 loaded and couldn't downgrade. The new version you are mentioning is the S2 app. The S1 app is not updated since March 7th. Shouldn't that one get the same downgrade functionality?

 

If I download the S2 app, it won't "automatically" try to update any compatible units to S2, thereby damaging my system? I can just install the S2 app, downgrade the Move and then uninstall the S2 app and reinstall S1?

I don't know that the Sonos S1 Controller will ever be upgraded to have the downgrade from S2 to S1 capability.

However, if you download the Sonos app ("the official Sonos app" ... version 80.06.03 for an iPhone, for instance) and start the app, it will search for products, but should not find any, IF you are only using the Sonos S1 Controller for your system.  Also, it shouldn't find your Move Gen 1 if you have reset it to factory default (indicated by the product showing a flashing green light).

The app should indicate "No Products Found" and give you the option to go to System Settings. Once in System Settings, go to Visit Help Center. There choose the option Downgrade Product to S1.

Follow the steps indicated by the app.  You should be able to downgrade your Move Gen 1 from S2 to your desired S1.  Once that is completed, use the Sonos S1 Controller to add your Move Gen 1 to your system. 

This is a brief summary of the steps to take. Sonos support has some more detailed documents on both how to reset your product to its factory default and downgrading S2 to S1. (Search on support.sonos.com)

By the way, you do not have to (and probably do not want to) uninstall the Sonos S1 Controller when you install the new Sonos app.  You can have both on your iPhone at the same time. If you uninstall the Sonos S1 Controller, you could risk losing your system info and have to start over in setting up your system.

No, uninstalling the S1 controller will have no affect on your system. All configuration is stored in the speakers.

When you re-install the S1 app you may have to press a button on one of your speakers so it knows which system you want to control.
