Dears

For one of our project we have 4 sonos connect and many sonos s100 play5 in different areas.

i am facing problem i have updated my app from sonos s1 to sonos s2 i can see all my sonos connect and can control them very well as well i have sonos s100 play 5 in control.

1- We have crestron touch panels in this project and it seems they dont have compatibility for S2  is there a way to roll back the system to S1,can i control s100 play 5 wireless speakers with sonos s1 app..?

2- Cant see sonos s100 play 5 on wireless network unless i connect them to a wired one is there any setting to be done as i dont have LAN in all locations of sonos s100 play5.
