I have two original version Play1’s that I was using on my home system; I bought a new Boost and have taken the old Play1’s to my summer house. I attached the Boost to the summer house WiFi (ethernet) OK but the Play1’s won’t add. Did a factory reset to one of them and wired it to the router and it forced an update to it. but then, that play1 was recognized by the app as its own system and not associated with the Boost - the Boost kept asking me to add a speaker - I unplugged the play1 (both power and ethernet) and restarted the Play1 but no dice. Tried moving the speaker next to both the Boost and the Router and no diff. Not sure what I should do next. . .
