Add support for full local access

Hello everyone

I want my Tumble Dryer to works full offline.
I got it paired with my Hon account, got it under HA too
Then I removed the internet access for the tumble dryer, and no sensor are updating anymore...

Device : CSOE H9A2TCE-47

I use to connect devices during the add on installation for other addons (like Tapo, for example), then remove the internet access to them, and they're still accessible locally (I am sure the device is accessible in local network)

Is there a way to have sensor updated without having to expose my device ?
