Do UltraPro Z-WAve Switches have local control?

By local control, I mean if the Z-wave hub is down will the switch still work as a dumb switch and turn the lights on/off?

This is the product I would like to get, but can't find if they allow 'dumb switch' operation. Does anyone have experience with these? https://byjasco.com/ultrapro-z-wave-in-wall-smart-switch-with-quickfit-and-simplewire-white

Thanks!
