Battery operated 2k doorbell sending alerts for no reason

My doorbell has been up for over a month with no issue.
I’ve recently added a door sensor and alarm keypad and again had no issue.
Today however I’ve had hundreds of alerts on my phone telling me motion detected, however the doorbell hasn’t recorded anything.
Detection sensitivity is minimum and I’ve put an area in place since the start which has meant I get no false detections.
It’s quite windy today, so I’m thinking could that be an issue? However we’ve had windy days since the doorbell has been fitted so I’ve no idea what to do.

Any ideas anyone?
