Nord Pool and current state node

Description

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.
