Tibber, a switch and MQTT

Description

In this example, data is read from Tibber and used to turn on/off a switch, scheduled by the ps-best-save node to be off up to 5 hours in a row, but only if at least 5 cents/øre is saved per kWh. Data is also sent to MQTT, for example to be displayed on Magic Mirror.
