Would'nt it be a good idea to not sync all of the entities from Home assistant to iobroker?
In the FHEM-Adapter there is a possibility to filter just what you need to be synced by adding "iobroker" as room name in FHEM. If doing so, just "objects"/devices which are in room iobroker get synced to iobroker an all the others are not synced but fully functional within FHEM (for automations and so on).
The only problem I see is, that you actually can't set such an attribute for each entity but only for whole devices in Home assistant. But even that would be better to sync only devices and their whole entities which belong to a room iobroker instead of just syncing all of them.
As a workaround I deactivated all the entities I don't need in Home assistant and iobroker, but others are needed in Home assistant but not in iobroker.
