```
{% endraw %}
If the template accesses every state on the system or all states under a specific domain, a rate limit of one update per minute is applied. If the template only accesses specific states, receives update events for specifically referenced entities, or the `homeassistant.update_entity` service is used, no rate limit is applied.
In the below example, re-renders are limited to once per second:
{% raw %}
```yaml
binary_sensor:
- platform: template
sensors:
has_sensor_unavailable_states:
value_template: '{{ states.sensor | selectattr('state', 'in', ['unavailable', 'unknown', 'none']) | list | count }}'
```
{% endraw %}
