Hi @Ejenkins57
Welcome to the Sonos Community!
You can take your Roam to the second location and use it on Bluetooth or on WiFi, but it cannot become part of the other Sonos system without being reset. You would then need to reset it again for it to once more be part of the first system.
If you don’t want to reset it, and assuming that the app on your phone “knows” both systems, it might be best to follow these steps:
- At home 1, where the Roam currently is, reset the Sonos app and choose “Connect to Existing System”. This will erase the app’s knowledge of the second system.
- Take the Roam to home 2, as well as a spare phone/tablet.
- The Sonos app is not written to be able to switch between two systems on one WiFi network, so install the Sonos app on the spare phone/tablet and connect it to the existing system at home 2.
- Turn on the Roam and open the Sonos app on your (first) phone - it should say that it can’t connect to your system. Tap Fix It and follow the steps on the screen to connect your Roam to the new WiFi.
To be honest, it may be easier to just reset the Roam and add it to whichever system you’re with.
I hope this helps.
