Details regarding MQTT communication

The MQTT communication is currently mainly intended for connection to openWB.

This means, once activated, the following topic will be subscribed:
openWB/lp/1/AConfigured Stromvorgabe in A

And these topics will be published whenever a new Modbus transmission is complete:
openWB/set/lp/1/plugStat Status, ob ein Fahrzeug angesteckt ist, nur 0 (nein) oder 1 (ja)
openWB/set/lp/1/chargeStat Status, ob gerade geladen wird, nur 0 (nein) oder 1 (ja)

The examples mentioned above are for load point 1. The 1 in the topic can be replaced by another number using cfgMqttLp (see above).

Details for openWB 2.0
