According to this article, https://support.sonos.com/s/article/4786?language=en_US
The symfonisk should work with both the S1 and S2 apps. However, I cannot get mine to do so. Even after a reset when I try to add it to a new system via the S1 app I’m told it will only work with the S2 app and it need to download the S2 APP.
I have a gen 1 S5 so can only use the S1 app for a complete system.
