Hi. I have just got an ultimate for the bedroom and all went very well until I had to ask the Harmony to learn the IR signals to control our new remote control ceiling fan. I've used the app to make teach the IR codes one by one into the hub as instructed , they accept no problem, the remote synchs as normal but not one of the the functions works the fan functions, tried the remote only, hub and blasters but no joy. The original remote is IR based. I'd really appreciate some things to try, Thanks.
