 ### Binary Sensor Support
 
-Binary Sensors must have a `sensor_class` set. Accepted `sensor_class`es are `moisture`, `motion`, `occupancy`, `opening` and `smoke`.
+Binary Sensors must have a `device_class` set. Accepted `device_class`es are `moisture`, `motion`, `occupancy`, `opening` and `smoke`.
 
-For binary sensors with the `opening` `sensor_class` you can also set `homebridge_opening_type` to `window` to have the entity display as a window instead of a door to Homebridge.
