I’m just getting started into the HA scene, and recently picked up a Leviton 3 Way Switch to use in my hallway from Home Depot.
The switched is being used as a 3 way switch, with the other switch still being the default/original switch, and not the coordinating 3 way switch.
Now, I’m not sure if I installed it incorrectly or not. However, the Leviton switch will turn on and off the hall light. However, the 2nd/non smart switch needs to toggle on, off, on, off to turn the light on. I think its because it needs to ‘clear’ the smart switch first to turn it on?
