disconnected shelly - `RuntimeError: Already initializing` about core

[thecode]

Thanks @Anto79-ops.

I am trying to see which code paths can cause this problem, in the meanwhile if it happens again, Please enable Debug for Shelly integration, wait for this error, disable debug and attach the log.

Note: it is better to drag the log into the comment (which will add it as an attachment) and not copy paste as it is hard to read logs in GitHub.

@thecode just happened again. Here's a timetime:

The Shellly goes offline at 17:53 (all entities unavilable)
The above error gets logged again at 21:54
I turn on debug 22:02
The above error gets logged again at 00:57 the next day
I turn off debug at 05:31

At thins point I unplug and plug the shell back in. and its working again.

I don't why this happening, but I recently enabled BT proxy for the Shelly for active scanning. I will turn it that off in case it causing stability issues.

Thanks @Anto79-ops your log show that we try to connect to the device while previous connect attempt is still active:
