/**
* Represents a MQTT Select component for Home Assistant MQTT Discovery.

* options through MQTT into Home Assistant as a Select. Every time a message under the
* `state_topic` is received, the select entity will be updated in Home Assistant and vice-versa,
* keeping the device and Home Assistant in sync.
*
* For detailed documentation see:
