[Bug] After homebridge restart cover status not correct.
**Describe the bug**
After restart of Homebridge cover state is not correct, it shows opening or closing. After setting a value via home or wall switch it will be updated and is correct.
Seem to be the status is not polled from the Shelly after hb restart.
And or the target value is not set to current position value what resulting in a moving state state closing or opening.

it would be nice if you could have a look, if you need something else pls me know.

The CoAP is fully working.
