HUE Unavailable Device in HA but still working in HUE App

Hi everyone,

iam running HA and HUE since quite some time. I have non HUE Smartplugs (Osram) which are connected to the HUE Bridge so i can switch them on and off. They become “Unavailable” in HA after some time however they are available and i can switch them on and off in the HUE app. Some time back i fixed the issue with the option “allow_unreachable” but this was removed so i now have the issue again.

Any idea how i can fix it ? As said only HA thinks the device is unavailable i can turn it on and off in the HUE App without issue. Once this is done it becomes available again in HA as well until it disappears again after some time.
