Funny, I was going to post exactly what cfrance asked.
Installed Roomie last night on iPad Mini, it found my Yamaha receiver immediately, but not the Oppo 103. Manually entering IP and port for the Oppo didn’t help, even after cycling power on everything. All devices are hardwired to a hub connected to my main router.
This morning I was going to try assigning a static IP to the Oppo to see if that helped, but after a long delay on the first button press, Roomie started to control the Oppo.
One question: do I need to assign a static IP to the Oppo anyway, so Roomie can find it after DHCP assigns a different address?
Very nice app, by the way. I’ve used four different Harmony remotes since the very first EasyZapper, Roomie is so much simpler.
