I have several Play: 1 speakers, sub, playbar, boost and a Sonos One SL speaker. I’m running wifi on Mesh system (as my house is pretty big).
A month ago or so the system was running just fine and I was able to group One SL speaker with older Play:1 speakers. Now I’m unable to use One SL speaker because in the S2 app it requires to be updated. So when I try to update it the process just stops at some point and shows an error message 1 (of which I couldn’t find any info in support section). I’ve tried rebooting the whole system and router. When I unplug the One SL speaker the rest of the system is running fine. Why can’t One SL speaker finish update?
Here’s couple of pics of the app and thebupdate error. Apologies for the Finnish language.
