With zwave you can buy a regular switch and an auxiliary/accessory switch. The aux switch is much cheaper than the regular switch. I have not found anything similar with insteon. Does it exist?
Do you have to do something special with the plugin to make a 3-way switch? Is the linking of the two switches done physically on the switches or on the plugin?
