Need help on a 3-Way Switch for dusk til dawn

I’m very new to the smartthings community. I recently got my Nest thermostats on ST as well as my Schlage lock. I’ve been playing around with some of the features but in no way am I a programmer.
I have some outside lights that are on a 2 way switch (one switch by my front door, and one switch in my garage) and I want to replace those switches with something that is compatible with ST that I can set it to turn off and on at a certain time.

Thank you in advance for your help.

Unless I’m mistaken, that’s actually referred to as a “3-Way Switch” (because there are 3 combinations: up up, up down, down down).

Do a Search :mag: of the Forums for “3-Way Switch” and you ought to find a one or two Topics that recommend the best type of Z-Wave / SmartThings wall switches to install. Usually you will require a “neutral wire” in the switch box (not just power + load). But that stuff is discussed in the various 3-Way Topics.

Any of those compatible switches will very easily be controllable by the default SmartThings on/off schedule Dashboard Solution SmartApps or other SmartApps.

I use the leviton DZS15-1LZ for all my non dimmable 3way applications. I also would be remiss if I did not point out that 3way is done a little different in zwave. You DO NOT use 2 DZS15-1LZ you use 1 DZS15-1LZ and also a Leviton VP0SR-1LZ remote at the other location


you are right - my wording was very misleading. It’s a 3-way switch at 2 locations.

@LadySapphy - awesome! Thank you for the info.

Before you buy anything, you need to make sure you have always on power in at least one of the switch boxes.

@Todd_Whitehead - do you mean one of the switches always has to be on?
