I am using the WF2IR to control several media devices. The blaster is located on a wall near a window approximately 12ft from the devices it controls. It is configured as a blaster in port 3 of the iTach. I guess, due to its position, there may be a high level of background IR, however, my other standard remotes work fine from this location. The blaster works 90% of the time- the iTach is definitely sending a signal every time. Is there an alternative blaster available (I notice that the supplied blaster has a smaller size LED than most other remotes), as the supplied blaster seems to have quite a narrow beam and isn't as powerful as I would like?
