Expire don´t work at mqtt Switch


i have some Plugs connected with zigbee2mqtt. In my items File i set a expire about 30m to turn off The Plugs. My Problem: The expire never expires…

I think it’s the mqtt status updates. They come about every 15 minutes. If I set the Expire to 5 minutes everything works fine. Autoupdate=false does not bring any improvement. I know I could solve this with an additional switch and another rule, but is it easier?

This is how expire is intended to work.
autoupdate won’t affect that, as it is about commands.

I think I’d do it with a rule and timer (no proxy Item required)
