Whoops! Forgot to post this! Here’s the latest handler for the Zooz Zen22 dimmer. Note that is you have one with firmware 1.06 (released April of 2018), you should be able to upgrade the firmware all the way to the latest (3.02) and beyond.
As far as the switch, this is a great little switch with more features than most will ever use!! Make sure and check out the readme (it looks better than the embedded if you click the link).
