# 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](https://magicmirror.builders/).
