Zooz Zen30 Hardware Versions?

I'm in the middle of a Zooz firmware updating marathon.

Is there any other way to determine what Zen30 hardware version a device is without looking at the front plate? I really want to avoid taking all of my plates off the wall if possible.

Did someone say Zooz? :wave:

The current firmware version will tell you.
You can reference this as well which helps match up hardware and firmware: https://www.support.getzooz.com/kb/article/393-zen30-double-switch-change-log/

For the most part the major version of the firmware indicates the hardware version.
