Wink zwave switches as lights

Hi folks,
So the house is now humming away nicely and very happy (except for the longer than 10 sec warnings in the logs).
I’m now spending time on refining and wanted to change the wink zwave GE wall switches, that appear as lightning bolts and switch.blah.

i’m aware of light templates, but that seems overkill. I was hoping to be able to change:
device_class: Light in customize, but the docs dont say that is supported.

This seems like a simple add for on/off switches?
