I have Dish network with several tvs in different rooms. The main room already has a Harmony remote control which works great with my complicated system. I have another TV in a different room with DVD player that I would like to also use a Harmony. I understand that the Dish receiver uses IR for my main setup and that any additional rooms will communicate with that receiver through RF. Question, can I use a second Harmony remote to communicate with the Dish receiver using RF? Any google searches have left me more confused as I am reading that they Dish is a special exception to the RF rule for Harmony remotes. Any support before purchasing another remote would be helpful.
