 Home Assistant adds extensions to allow templates to access all of the current states:
 
- - 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`.
- - `states('device_tracker.paulus')` will return the state string (not the object) of the given entity or `unknown` if it doesn't exist.
- - `is_state('device_tracker.paulus', 'home')` will test if the given entity is specified state.
- - `is_state_attr('device_tracker.paulus', 'battery', 40)` will test if the given entity is specified state.
- - Filter `multiply(x)` will convert the input to a number and multiply it with `x`.
- - Filter `round(x)` will convert the input to a number and round it to `x` decimals.
- - `now` will be rendered as current time in your time zone.
- - `utcnow` will be rendered as UTC time.
- - `as_timestamp` will convert datetime object or string to UNIX timestamp
- - `distance()` will measure the distance in meters between home, entity, coordinates.
- - `closest()` will find the closest entity.
- - `relative_time(timestamp)` will format the date time as relative time vs now (ie 7 seconds)
