Error handling message: **Integration '' not found** (unknown_error)

Hi,

I just started with Home Assistant a week ago and still trying to find my way, earlier I noticed the error message below, which came today again at 13:50. Not sure where to look and thus how to solve it. It looks like HA is trying to call integration related to my iphone or Companion app which does not excists anymore.

Hopefully someone can point me out where to look or how to solve it.
