Fixed
- Home Assistant logged an error for every published device: the
maintenance channel'sSTICKY_UNREACHwent out as aswitchwith
device_class: problem, a class onlybinary_sensorknows, and Home
Assistant refused that component ("expected SwitchDeviceClass or one of
'outlet', 'switch'") while it created the device and its other entities
(B-39).STICKY_UNREACHis no longer announced at all - the maintainer's
decision: "UNREACH is enough" -, and a device class a platform does not
accept is dropped from any component before it goes out. A test now checks
every component of every device the shipped paramsets know against Home
Assistant's device classes per platform.
