I just did the same yesterday (LRM-AS and LTM-5). I also used the same minimote directions and it worked great. If you are like me the main switch will be turning off the aux side hot which will be wire-nutted to the load (at the aux side). Since you need a neutral and a hot on the aux side I used the traveler for this (attached the traveler directly to the hot on the main side and then connected it to the hot on the aux switch).
