Avoiding Interference
If you are having trouble with your Sonos Speakers (playback issues, trouble pairing speakers, players disappearing from the controller in the App), the most likely cause is wireless interference.
Plume's optimiser already chooses the best 2.4Ghz channel for use in your network, so the cause is likely that your Sonos is too close to another wireless device or your pods. Keep your Sonos at least 1 metre away from your pods and other wireless devices to avoid these issues.
Wiring Sonos Speakers
We recommend that you connect one, and only one, of the Sonos devices (Sonos speaker, Sonos Connect, or Sonos Boost*) via Ethernet to one of the Plume pods and have the rest of your Sonos devices connect via wireless to the network. This enables the Sonos speakers to form their own ad-hoc network, independent of the Wi-Fi network in the house (BOOST mode).
*If you have a Sonos Boost device, if possible, that should be the one device plugged into the Ethernet port on the Plume pod.
Connecting multiple speakers to Plume pods will cause a network loop issue so please make sure that only one of your speakers is hardwired to a pod.
Remember to power cycle the pod after connecting the Ethernet cable so the pod will properly recognize the device and keep the Sonos player at least 1 meter away from the pod.
Connecting Sonos to Plume using Wi-Fi
If you want to connect your Sonos players to your Plume network using Wi-Fi, make sure that you've updated their firmware to version 45.1-56150 or later. If you are running an older version of Sonos firmware when connected over Wi-Fi, the players will lose their connection whenever the Plume network sends out a Channel Switch Announcement (CSA).
