In this example, data is read from the Nord Pool sensor in HA via the `current state` node. The `ps-best-save` node is used to control a water heater via a switch, controlled by `call service` nodes in Home Assistant. The schedule is printed to a debug node. An `inject` node is used to trigger the reading of the Nord Pool sensor every hour.
