The processor was set up with the static ip address of 192.168.10.75, subnet of 255.255.255.0, with the gateway of 192.168.10.1. The AV guy had integrated a remote control for the AV that would also control the lights. All was working great.
Today I went to add a couple of scenes but when I went to upload the programming, noticed it wasn't communicating with the processor. I did an ipconfig and saw that network was changed completely to 192.168.50.x and when I ran a network scanner, the Lutron processor was not showing up at all presumably because its IP address is a host for a different network.
Here is the weird part: The remote control is still working. Is it possible that the remote control is somehow able to connect to 192.168.10.75 from 192.168.5.x? Normally, I'd call the AV guy and see what he did, but there was some sort of drama and he may not be available but I can't find the processor on the network and if I connect directly and change it, then for sure the integration link would be broken. So I guess my biggest question is it possible for the remote control to communicate with the QS processor even though they are on different addressing schemes? Can the switch just pass along the traffic without going through the router? I'm trying to figure out whether the AV guy used some networking trick to make sure his remote could reach the processor on purpose or this is just an accident. I'm kind of in a weird position here because the remote is technically working (somehow) but I can't make any changes. I hope the AV guy comes back.
