ZOOZ is a brand of smart home devices that all use the Z-Wave protocol to communicate with your home automation hub, in my case Samsung SmartThings. We have covered a handful of their items in recent reviews at Bigbruin.com, including their ZSE01 indoor siren and their ZSE18 motion sensor. This time around I am checking out their Zen26 Z-Wave Plus S2 smart switch which is promoted as offering a simple solution to making 3-way and 4-way circuits smart.
