I want to emulate a 2-way switch feature between 2 smart switches. I used smart lights smartapp to assign each switch to turn on/off the other. It works as expected the first few minutes: Turning on/off one physical switch would turn on/off the other light within a second or so.
However, after a few hours if I turn on/off one of the switches again, the other light won’t follow until several minutes later. I am guessing ganging the 2 switches to each other created an infinite loop which manifest itself in this quirky behavior.
What’d be a proper way to implement a 2-way switch?
