 - **entity_id** (*Required*): The entity to monitor. Only [sensors](/components/sensor/) and [binary sensor](/components/binary_sensor/).
 - **name** (*Optional*): Name of the sensor to use in the frontend. Defaults to `Stats`.
 - **sampling_size** (*Optional*): Size of the sampling. If the limit is reached then the values are rotated. Defaults to `20`.
+- **max_age** (*Optional*): Maximum age of measurements. Setting this to a time interval will cause older values to be discarded.
