Error doing job: Task exception was never retrieved

[SteGe88]

On my Home-Assistant instance I got frequently the message in the logging: Task exception was never retrieved, with a bunch of python traceback messages which are not making any sense for me :-)

I have had also the debug logging enabled, but there are no hooks to the problem as far as I can see. I have three p2000 sensors in my config (see bellow) and when I enable just one of the three (doesn't matter which one0 I got the same message.

Config:

  name: p2000 Informatiemanager

  scan_interval: 20
