Factory resets of Sonos speakers are not a good idea except when transferring ownership.

I suggest adding them back to your system as individual speakers first.

Then try powering off your router and all Sonos.  Power the router fully back up, then power on wired Sonos devices (if any), then Playbar, then Play:1s.

That often works, but not always.  Please post back either way.

Hi @evov.

Thanks for the immediate response and for submitting a diagnostic.

Based on the provided diagnostic, it seems that the Sonos App is not even detecting them to be fully-added to the system. I would suggest since while the device is flashing green, add them first as individual music speakers configured in a separate room and once both Sonos Play 1 have been added back to the Sonos App, then we can proceed on add surrounds.

If the above statement would not work, I would suggest contacting our technical support team so they can further investigate what is causing the issue.
