Pre-Purchase questions on Ring Elite

I have family members that sometimes live with me, and sometimes at another home. Can the ring elite only notify members in the house when they are actually in my house? (maybe only notify members on the local wifi?)Also, I currently don't have a door chime on my existing doorbell (which is a PoE doorbell also - I think by Elan). I assume this doesn't really matter - I could just purchase the Chime 2nd Gen and put it anywhere?
