First, sincere apology if this in not the correct NG to answer my simple
electric circuit design requirements.



At home in the stairway i have two 3-way switches driving one light fixture
(120W Max.), one switch upstairs the other in the garage.

They are wired in a power runs Switch-Switch-Fixture mode. The A.C constant
power source is in the garage switch.



I would like your ideas to find an elegant solution to eliminate the manual
switching function replacing them with a one-minute timed push button.

Ideally, i would prefer a 100% cybernetic solution; replacing the switches
with sensors (motion? IR?). The doors are always open so I can't use them as
triggering point.



Thanks in advance for your help,



Manuel

PS: The wife thinks this is an extravagant luxury, of course she never goes
upstairs with both arms full of grocery bags and in the dark :)

Thanks a lot for the responses. I got the answer from Tim; Leviton has the
sensor i was looking for.
