Perhaps a silly question, but I’m finally going to move to Ignite tv and I’m wondering if the remote is infrared? I was hoping to hide the set top box but I don’t know if it needs to be in line is sight to work?
Just got Ignite TV 2 days ago. However, for you question, the remote is IR.
Once properly paired to the IgniteTV box, the IgniteTV remote uses RF and you can "hide" the box if desired. As for controlling other devices, the IgniteTV remote uses IR since most devices like TVs, AVRs, Sound Bars, etc are IR.
The Harmony remote is IR. Hope you get the "directionality" sorted. The IgniteTV box has an IR receiver/eye indicated by some small triangles at the top right corner? Make sure that is "visible" by the Harmony. It can be directional based on feedback in other threads.
