Home Assistant classifies supported Fibaro, Shelly, Aeotec and ZVIDAR motor controllers as shutters, blinds, gates or shades according to their device and operating mode. A gate can consequently appear as a garage door through HomeKit, Alexa or Google, instead of being classified as a window.
Owners who use the old window device class in cover triggers, conditions, templates or dashboards need to update those references. Some Fibaro FGR-223 and Shelly Wave Shutter configurations also stop creating a separate slat cover: the main cover provides tilt control, and the leftover slat entity can be removed.
