Mqtt data from AhoyDTU "unavailable" after HA reboot

Hi,
i have the issue that everytime after a HA reboot it doesn’t display the mqtt values sent by ahoyDTU anylonger. They are just displayed as “Unavailable” despite mosquitto and ahoyDTU sending them in decent intervals.

HA displays the values only if I start the discovery on the AhoyDTU manually which is kind of annoying. Retaining Flag is activated in the AhoyDTU and AutoDiscovery was used to add the mqtt values to Homeassistant which worked very well.

Does anybody haven idea what the issue could be?

Best,
John

I’m in the same boat.
Every help would be appreciated.

Thanks

EDIT: Never mind… Didn’t work…
