Sensors

What the app can report back to your home, and what each reading costs.

The app can report readings from your phone back to your home, so automations can use them: turn the hallway light on when you get home, pause the music when a call comes in, warn you when the phone is nearly flat.

Every sensor is off until you turn it on. Open Settings → Sensors, pick one, and enable it. Nothing is reported before you do.

Some sensors need an Android permission, and some cost noticeably more battery than others — location most of all. Each entry below says which.
