Device offline Error in Log when device is unpluged

[Grizzelbee]

Describe the bug
The adapter throws the error: 2023-12-01 12:26:03.973 | error | {"traceId":"1701429963616","code":-11300030,"msg":"device offline","module":null,"stacktrace":null,"result":null} at every poll when the device is unpluged.

To Reproduce
Steps to reproduce the behavior:

1. Unplug the device
2. wait for next poll

Expected behavior
Set a device reachable indicator to false and turn the adapters traffic light to yellow instead of continously throwing this error - which is none.

Versions:

• Adapter version: 0.0.3
• JS-Controller version: 5.0.16
• Node version: 18.13
• Operating system: Debian 12 Linux

I started the adapter with the device plugged in and unpluged it shortly before the error starts occuring. From that point on it occurs every 2 minutes (=poll intervall) until I plug it back in again.

please try GitHub version

[Grizzelbee]

Github version doesn't throw the error anymore but logs a proper info instead - that's pretty good.

But... The ConnectionState of the device still stays "online" (but should be offline):

And should go back to "online" as soon as the device reconnects.

EDIT: Why does the offline message apprear that often?
