Need help finding duplex smart light switch

Hardware

Hi All,

I’m working on automating a stairway light and need a duplex smart switch. Any ideas where to find one? Any integration is ok.

Thanks in advance, Bill

Update: found this on Amazon

I will be opening the switches tomorrow to see how they are wired

Duplex smart switch?
You mean two (or three) way switch configuration?

You could use a ZigBee switch on one end and a real smart switch on the other.
We have that in our hallway, it only had one switch by the door, so I just bought a cheap IKEA on/off ZigBee switch and now it controls the wifi switch on the other end of the room.

Maybe consider the Sonoff Dual R3 Mini R2:

Another option might be the Shelly 2.5, both of these assume that you have live and neutral available behind the switch.
