I have a Harmony 659 and a 628. I would like to set up the HR20 with the 659 in the living room and use the Hr20 remote (I believe it is IR capable) in the BR to control the HR20 that is in the LR. The Hr20 will be hooked up by component to the LR HDTV and by coaxial to the BR TV. Then I would like to keep my extra 10-250 also in the LR to hook up OTA(I get Toledo OTA and am in the Detroit DMA). I would like to use the 628 to control only the 10-250. Can I program the 628 to only work on the 10-250 or will it interact with the HR20 as well? Same question for the other two remotes. It would be great if there is a way to program the 659 to control the HR20 and 10-250 separately but that is probably asking too much.
