Did look for this on the forum and in the documentation, but my German is not that fluent.
After syincing with gassistant-fhem Google is no recognizing all my fs20su as lights but as general-purpose devices. (A switch-icon in the Home app instead of a light-icon)
When asking google to switch off all lights in a room, it does not switch them off as he thinks these are not lights.
Is there a way to configure (or tricking Google) that these are (none dimmable) lights and not general-Receivers/Actors ??
Most likely there are at least two ways to influence that kind of behaviour.
One is the model attribute (see cref for FS20), second is the genericDeviceType (linked to several speech recognition solutions afaik).
So first step would be to check both of these options.
If this is not leading anywhere, you should at least post a "list" of your device to give further hints to other helpers.
Kind regards,
