        Timertick script version 1.0


        Creates (if needed) and updates two timertick items with a minute and hour value to be used for refreshing graphs.

        CRON should not be to fast for the minute value (graph will flicker during update). 

        15 minutes is fine (for a graph showing 1 or 2 hours).

        The hour timer can be used in day graphs.


        Usage, in a widget add a key in main compomnent f7-card referring to this item (with a string to make it unique)


        component: f7-card

        config:
          key: = "fan" + items.timertick_hour.state
