So not really sure where to put this as its more of a curiosity than a issue or project.
Anyway, anyone know what task HA runs every 15 minutes? I don’t have anything scheduled so wouldn’t be specific to my setup I think. I noticed this as I have a passive infrared (PIR) sensor connected to my PI and I often get false positives on the hour. It e-mails me when motion is detected and Im away and its always right on an hour.
Why on the hour and not on any other intervals I don’t know but I read that EMI from local devices can often trigger a PIR sensor and noticed that the CPU is loaded on the hour.
