I will be pushing out a driver update this Saturday (Feb 12, 2022) that will require a hub reboot.
This update will add the dimmer’s default level as a custom capability so that it shows on the detail view and can be used in automations.
Adding custom capabilities to drivers is currently a bit messy - when your hub receives this update the driver will hang, and hub control (app control, routines, scenes, events, smartapps) of your motion switches/dimmers will become nonfunctional. Physical control (including motion activation of the light) will still work. I anticipate that you’ll be impacted by this even if you only have motion switches, and no dimmers.
A hub reboot will be required after your hub receives the update to restart the driver and resume hub control. The easiest way to reboot your hub (and the only way to reboot your hub remotely) is, ironically, through the Groovy IDE’s My Hubs tab.
