I’ve seen lots of similar posts before, but most of them seemed to suggest problem was with a Camera platform. I don’t have any cameras but I get these all the time (sporadic, but lately about every 10 mins).

ConnectionResetError: Cannot write to closing transport

Any suggestions?

I’ve been so annoyed with these and other random and repetitive log entries that I have solved it with:

logger:
  default: critical

in my configuration.yaml
