Delay sending picture from camera

I have a flow that when a motion detector registers movement I send a snap-shot picture from my IP-camera to my phone as a push. This should only be done if no-one is at home, which is based on UniFi presence. I would like to change so that i take the picture when the movement is registered but if a phone connects within 1-2 minutes I do not want the push. This is to avoid pushing when I get home myself or my family.

So if the phones have connected to the UniFi network within two minutes no picture should be sent. I cannot wait two minutes with taking the picture.

This would require Homey to temporarily store the image, which (AFAIK) isn’t possible.

OK, thank you

Images will be stored in Homey Developer Tools ?
So with the image grabber app this should be doable?
