Configuration Example: openWB via MQTT
Modify cfg.json (using http:// ip /edit):
- cfgMqttIp: IP adress of openWB ("" to disable MQTT)
- cfgMqttLp: Mapping of Modbus IDs to openWB load points, e.g. [4,2,0,1]: Box0 = LP4, Box1 = LP2, Box2 = no MQTT, Box3 = LP1
Example:
..."cfgMqttIp":"192.168.178.1","cfgMqttLp":[1],"cfgMqttUser":"optionalUsername","cfgMqttPass":"optionalPW"...
...
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).
