Zooz ZEN21 v3 Z Wave Switch

Zooz is a brand of Z-Wave devices that I hadn’t heard of until recently. But after discovering them, and quite liking the price of the units (~$27). They have become one of my favorite devices. Frankly, what isn’t to like about a device that works, and makes it really easy to support a 3-way install?

Device properties:


  • Cheap
  • Works well
  • Supports 3-way installation without a separate add-on switch


  • Switch white, doesn’t quite match the white of the wall plates in my house
  • Wiring a 3-way is a bit tricky because the manual isn’t awesome
