6 months ago I have created a Pull-request which should fix this issue: https://github.com/tahvane1/jablotron80/pull/174
It seems to be the resault of unhandled exceptions during the reconnection (jablotron.py:888). By adding an if statement for host is unreachable and connection refused
except serial.SerialException as ex: if "timed out" in f'{ex}': LOGGER.info('Timeout, retrying') elif "Connection refused" in f'{ex}': LOGGER.info('Connection refused by remote serial host, retrying') elif "unreachable" in f'{ex}': LOGGER.info('Remote serial host is currently unreachable, retrying')
has fixed my issues.
I connect to JA via Serial2Net socket connection. However when there is a network update/reboot or temporary disconnection (i.g. maintenance ) and the connection is interrupted the HA integration fails with unhandled exception. As a result the connection never restarts and the integration is dead (first issue) but all sensors /integration keeps showing as available and working (second bug)
Attached is the error log from HA: `This error originated from a custom integration.

The integration keeps showing as available:
I simulated this behavior few times, all the time python code crashes and never recovers /retry to connect again until HA reboot.
