Haven't tried home but works fine for me with smart lock when connected to my Bluetooth in car. Do note sometimes it'll lock and prompt you to unlock based on certain conditions.
I'll check adding home and see how it goes.
Edit: did a quick test and yeah adding home not working. Have to dig deeper.
Just an update, it's been working fine for me from yesterday evening. May be took few hours to learn about location etc but it recognizes I'm at home and says Unlocked because of smart lock.
