In my up to date HA system (all latest versions of core, etc.). I experience a strange behaviour of my LD2410C ESPHOMe radar sensor. I have it in place for over a year or even longer. Has been working great all the time. Triggering someone present in the bathroom and run an automation at night switching a light on. But last week this all stopped.
When lookking at all the involved part, at first glance it seems all ok and working. Z-wave dimmer, HA automation and even the LD2410C is running.
Looking at the LD2410C in HA shows like this, only strage thing for me is that it still shows activity while no one is in the bathroom or even near it. Might that be the problem?
Now the sensor is in the ceiling above the bathroom under the attic. So, I had a mice problem at the attic, could that messed up things? I’m not sure if there are still some mice around inbetween the ceiling and attic floor. Caught 6 or 7 of them 
did not see any activity of them last week.
How to troubleshoot this behaviour and not working of the automations? Your advises please. Thanks
