I have a light switch that controls the light on my front porch. It was clearly designed for incandescent bulbs as CFLs always flicker when installed outside when the light is off as if a small current is running through. This was apparently a common design with older timer switches if a "pilot light" style was not used. The timer is shot as well, so I thought it might as well be time to replace the whole thing.
I have an additional switch across the house that is a one-way switch to turn on the light over the garage door. I would like to be able to control both lights from both locations without having to redo any wiring. Do any of the "Works with Nest" light switches on the market allow such a configuration whereby you could link the two switches together to remotely control each other?
