Added a device template for my wii and SH-AC500D receiver (control receiver via USB uirt), learned all the codes. Changed the IR delay values to 1s after poweron. Went into setup wizard and assigned inputs on the receiver. Reloaded router and regened orbiters.
There's a 6 to 15 second delay when I select the wii scenario in orbiter before receiver switches inputs. It's always faster switching back to the MD input.
