ZEN21 VER. 2.0 VS ZEN26: What's the Difference

We like updating our products and making you happy. But with a growing number of versions and model numbers, it can get pretty confusing. 

So we combined and compared the main features of our light switches since they look similar and serve the same purpose. Here is how the ZEN21 VER. 2.0 (VER. 1.0 is ancient history so we're not including it not to confuse you even more!) compares to the newer model, the ZEN26 S2 On Off Switch.

The short story is that the S2 switches are much more flexible and easier to install in multi-point control circuits (you just need to replace the switch with direct connection to power and neutral with a Zooz switch and you're done). But since they use 2 travelers, there wasn't enough space to make them as powerful as the ZEN21. While they're perfect for your energy-efficient LED's, a large chandelier will be too much to handle for the S2 switches.

Not sure which version or model number you have? Just see the back of your switch, it's all printed there.

If something here isn't clear or you'd like to see more attributes added to the list, just let us know!
