- Iterating `states` will yield each state sorted alphabetically by entity ID.
- Iterating `states.domain` will yield each state of that domain sorted alphabetically by entity ID.
- `states.sensor.temperature` returns the state object for `sensor.temperature` (avoid when possible, see note below).
- `states('device_tracker.paulus')` will return the state string (not the object) of the given entity or `unknown` if it doesn't exist.
- `states('device_tracker.paulus')` will return the state string (not the object) of the given entity, `unknown` if it doesn't exist, `unavailable` if the object exists but is not yet available.
- `is_state('device_tracker.paulus', 'home')` will test if the given entity is the specified state.
- `state_attr('device_tracker.paulus', 'battery')` will return the value of the attribute or None if it doesn't exist.
- `is_state_attr('device_tracker.paulus', 'battery', 40)` will test if the given entity attribute is the specified state (in this case, a numeric value). Note that the attribute can be `None` and you want to check if it is `None`, you need to use `state_attr('sensor.my_sensor', 'attr') == None`.
