What is going on?

So I switched to Hass,io because my docker installation was freezing and I had to restart my Pi every week. Now my Pi is stable but the automations are acting up. Sometimes they work, sometimes they don’t, My HUE bulbs are getting random colors when they are triggered. The automations are very simple and the config UI doesn’t throw any errors.

My error log gives me this from time to time but I’m not able to find out what it is:
