I have the Lutron Bridge Pro on VLAN 10 and a Sonos Boost on VLAN 1 and an edgerouter x for the router. I also had a pico remote wall mounted in the kitchen programmed to control one of the Sonos speakers. I originally had both Lutron and Sonos systems on the same VLAN, and there was no issue with the pico. I have since moved the Sonos to VLAN 10. Assuming I keep them on separate VLANs, is there any way to allow the pico to control Sonos? Is there a certain port/protocol that Lutron uses to communicate with Sonos? Is this communication local or cloud-based? I'm assuming it's local because my Sonos is not directly accessible from WAN in the way that Lutron, Nest, etc are. It would be great if there is a firewall rule or rules I can create to make this happen. Any ideas?
