I've bough some Insteon light switches for my house. I've got some exterior lights that are wired out as 3 way switches. With the Insteon switches you can't replace them as a 3 way switch. You have to replace one side and wire it like a normal single switch circuit and then on the far end power another Insteon wall switch and then configure one of the buttons to operate the far end switch.
So on the side with power you install it like a normal switch and cap the messenger (red in my case) and then go to the far side and cap the messenger and tie the black and white together.
From a code/safety point is there anything wrong with removing the switch, capping the messenger, connecting the black and white and then replace the switch cover with a blank cover?
For those who don't know what Insteon is »www.insteon.com/dimmers.html
I'm using some dimmer and on/off and some of the 6 button switches. I'm installing 3 8 button switches in the master bedroom so I can control everything from one panel.--
I do not, have not, and will not work for AT&T/Comcast/Verizon/Charter or similar sized company.
