System log fills up with authenticated/associated (aid messages)

My alarm system from develco keeps spamming the router system log. Any good reason why?

  • Have you looked at the alarm's log?
  • Is this AP set to a DFS channel?

Uhm no, alarms log?
I've removed wifi connection for my smart security hub, it's now only connected with cable. Many of the authenticated messages are gone.
Now I find aid messages when my phone moves from my dump ap to my main router or the other way around.
I'm using my country in the wireless config and auto on channel selection. I don't believe it's a DFS issue?
