Hi @Anna118. This could be related to your Motion Settings and Motion Frequency. There are a few Community Articles that could provide some assistance! This article goes over setting up your Motion Zones and this one discusses your Motion Frequency. If possible, attach a screenshot of your Motion Zones so the Community can best help you optimize your motion detection. With you noticing this during a specific time of day, it may be relative to the position of the sun and the angle of the Doorbell. I hope this helps!
