Note: The sensor state was updating correctly (instantly) but battery drain on the Pixel 6 seemed excessive (~35% battery use over night when the phone was idle) so I decided to follow the Starting fresh with Android app instructions. Sensor state (sensor.ma_pixel_phone_state) does not update promptly as it did before. The sensor seems to update when the mobile_app is open.
5 minutes later (I think due to me opening MA’s Pixel HA mobile app to check settings / status)
