As you may already seen, Sonos has released S2 and the new S2 app.
Today, lutron sent out an email that older Sonos devices (that S2 does not support) may be impacted with the lutron-Sonos integration. Sonos warned users to possibly wait before upgrading to S2.
Not sure if this will also occur with the ST-Sonos integration so the same warning may apply to ST users at this point?
I upgraded but all my Sonos devices are S2 supported and they do work with ST. I don’t have any non-supported S2 devices such as the Play 5 (gen 1)
Other non S2 devices:
Connect (Gen 1)
Connect:Amp (Gen 1)
Play:5 (Gen 1)
