How do I get my 2 Sonos Connect Amps back onto the Sonos S1 app after accidentally resetting system

I am hoping someone can lead me in the right direction.  I have had the Sonos S1 app for about 8 years now. The Sonos S1 app controls 2 Sonos connect amps.  One amp controls the speakers in the outdoor seating area and the other amp controls the in ceiling speakers inside of the house.  While away in my vacation home where I use the Sonos app to control Era 300, Era 100 and One SL, I accidently opened the Sonos S1 app instead of the Sonos app to control the Era 300, Era 100 and One SL speakers.  Because it wasn’t working, and it shouldn’t have been because I opened the wrong app, I ended up resetting the entire system on the Sonos S1 app.  Immediately after resetting the Sonos S1 app I realized I totally screwed up because I was using the wrong app to control the Era 300, Era 100 and One SL speakers.  I should have been using the Sonos app which would have worked but was using the Sonos S1 app.  When I got back home I tried to use the Sonos S1 app and there is no system to use. When I tried to connect to an existing system via the app, I get an error saying the existing system could not be found.  How can I get the app to recognize the amps again so that it is useable?

I suggest you call Sonos Tech Support to explain your situation and allow them to assit getting your system up and running again. They will also (if applicable) be able to assist to upgrade your amps to S2.

The first four numbers in the serial number gives the manufacturing date. “1501” or greater is S2 compatible.

Do you know which version Connect:Amps you have? Do they have a pause/play button on the front?

If they do, you can upgrade them to the S2 app and then you would have no reason to use both apps. You would just have to join the systems at each home whenever you arrive at them.

I’m not sure which I have.  They are close to 8 years old.  Will check tonight and see.

the front of it has the mute and volume up and down buttons.  I ended up deleting the app and reinstalling the Sonos app.  Did a factory reset on both amps.  I was able to get both Spotify and SiriusXM working but I do not have any sound coming from any of the speakers.  It was late last night so I didn’t try messing around with it.  Will attempt to do so over the weekend.  Any ideas for why there is no sound coming from the speakers?  Spotify shows that music is playing, I just don’t hear anything.  I have a russound amp and all of the green lights turn on when I tried to play something on Spotify but I don’t hear any music from the speakers.

    The first 4 numbers in the serial number are 1401.

    That suggests the device was manufactured in January (01) of 2014 (14), which means it is S1 only, and can’t be upgraded to S2, due to memory constraints that are built in to it.
