MQTT Topic Forwarding

Local Topic

Input field for the local MQTT topic that is to be published over the MQTT bridge to the remote MQTT broker.

For a detailed description of the available local MQTT topics, refer to the documentation (see https://www.phoenixcontact.com/en-us/products/ac-charging-controller-charx-sec-3150-1138965).

If selected MQTT topics are to be published by all charging points connected to the local MQTT broker, the <Device ID> can be replaced by the wildcard “+”.

Remote Topic

Input field in which a designation for the MQTT topic can be entered to which a subscription can be created in the remote MQTT broker or that can be published by the MQTT bridge to the local MQTT broker.

Note:

The following topics are available from the MQTT bridge in order to be published on the local MQTT broker as well as the remote MQTT broker:

config: Payload {<Device type>, <Device ID>, <Name>, <Location>}

VPN_Connection_State: Payload {<vpn_status>, <vpn_ip>}

Forwarding direction (arrow)

Selects whether a topic should be published by the remote MQTT broker to the local MQTT broker or vice versa.

Information button

Opens a pop-up window that displays the topic under which the forwarded topic is published.

The charging controller automatically adds the hierarchy <Prefix>, <Device type>, <Device ID> to the topic. You can copy the entire topic to the clipboard and use it for configuring the remote MQTT broker (“Information pop-up for forwarding topics from the MQTT bridge to the local MQTT broker” on page 127).
