I have a detached garage what is about 200ft away from my house. Have 220v going from the house panel to the garage panel. Would have a spot light on back of the house and on back of garage and would like to be able to turn them both on and off from the house and the garage. Would X10 switches work? If o, what would I need to make that functional. Also, I want to use the switches to turn the light on and off not some remote to turn the switches on and off. Thanks.
