I have some x10 devices plus the maxi controller in my HT. I have 3 light switch dimmers, and 3 light module and 1 appliance module. I am going to be needing 4 more dimmers and a couple more modules. My question is about x10. Should I use something else and if so what? I have also been having a little problem with my switches not always working. Smarthome sold me a signal linc module but someone else said I should have a phase coupler first. Help me out here please. Thanks.
