So I just learned that apparently Home Assistant has absolutely no user account control. My roommate has no need to access the lights, electrical outlets, etc. in my room, and has absolutely no reason to be able to see my phone’s battery charge level and charger status.
there is a feature request with a lot of good comments on their forum. The summary of the last time I checked it was on the lines: “it is a reasonable request but it is terribly hard to implement it correctly and since we currently have no capacity to do it we prefer leaving it not implemented instead of offering any alternative which could give a false sense of security”
