But it seems that once a device is added to homekit, changes in the config for this devices are not reflected in the homekit app. I assume that after removing the home assistant homekit component and adding it again, the device would be shown as outlet. Is there an easier way to achieve this, since it would require to rearrange all items in the correct rooms.
That is what I meant. You can’t set your Dining Room Fireplace to be shown as an outlet, since it is a switch. Thats why I wanted to have an outlet in the first place.
Since you have both: I there any difference between a switch and an outlet other than the icon? Any different features?
Unfortunately HomeKit uses the type that the accessory first connects with. However you can temporarily exclude the entity with the filter restart, include and restart again. That should do the trick.
