Ok heres my set up. My house is 2400sqft. I have 8 decorator dimmer switches, 1 lamp module, 2 credit card controllers, and 1 palm pad remote controller. I have the lamp module in my den on two lamps. I have the decorator switches, 1 in the master, 1 in the master bath, 1 in bedrom #1, 1 in the hall, 1 for the porch light, 1 for the entry way light, and 1 in the kitchen, and 1 in the bed room bath. All incadescent and all above 60w. I have the CMA15 in the central part of the house, the living room. From the CMA15 to each end of the house is no more than about 40-50 ft. Im using the plam pad remote mainly and it controls everything but 1 switch in the bathroom and 1 in the hall. The bathroom turns off only by remote, not on. The hall turns on only by remote and not off. However ALL switched are operable manually directly from the switch. I have unplugged EVERYTHING in my house to check for noise and i still have the same problem. I have moved the CMA15 around, and nothing changes.
