Sharing is also easy, just create a separate partition with all the sensors you need to share and create a new user with password access. It is also possible to create users without App access but with a time limit keypad code access.
You can check the graphic of energy consumption to know how much you are consuming and when. You can also make sure if some electronics are consuming too much and need to be replaced.
