I'm finishing the wiring on my new house, and have encountered a county code issue. The county has a "dark skies"policy, where external house/yard lighting is either limited to max lumens, or the external lights must turn off automatically within ~10min after being turned on. The lights in question are controlled by a " (US) four-way" circuit (three switches), where the power feed is to one end of the string of switches, and the far end switch feeds the lights, just like this:
**broken link removed**.
The existing switch at the load end has a normal (Com, NO, NC) form C switch with power fed to it only on the travelers and it has Neutral available.
I need a "three-way switch/timer" (White, Decora) that is just like the normal "three-way" switch it replaces, except that it should automatically reverse the feed to the load from the "travelers" 10min after any switch in the string was last operated. Note that this requires the timed switch to be triggered either if the local handle is manually operated, or if any of the upstream remote switches causes a reversal of which traveler is hot.
I am either looking for a ready-made solution, or if necessary I will build my own circuit.
