Co-tenant covering my dbc

My co-tenant is a drunk and covers the dbc. She thinks I’m spying on her but I explained it only sends me notifications when someone rings the door bell, but it records events in case someone steals a package. She flips it off and covers it! She is a lunatic and I have to deal with her another 9 months! Any ideas?

Suggest she get the app on her phone and then share the access to the DBC via friends and family invitation. Potentially by sharing access to it she can see the benefits of having it.

There this thread on sharing devices

Either that or like @Haadsecure said tell her to leave your stuff alone.
