+It is possible to show a state without displaying a graph for a sensor.
+Imagine there are two CO-2 sensors & one humidity sensor; graphs are displayed for the CO-2 only, and the humidity is shown as a state only.

+This method may be also used to add a calculated value with it's own `aggregate_func` option.
