Adding data points - User Guide

This portion has to be done manually. Each point has to be created and have a reference to the MQTT connector. More documentation from Stackhub about “Parser” and “PointName” can be found here and look for those sections.

First, the user needs to create a local point in DB Builder.

Then add the following tags to read the current value:

pahoMqttCur (required - string type): /point/current/topic
pahoMqttConnRef (required - ref type): @id_of_mqtt_connector
pahoMqttParser (optional - string type): funcName
pahoMqttPointName (optional - string type): pointName

To make a point writable, it needs to have these additional tags.

pahoMqttWrite (required - string type): /point/write/topic
pahoMqttConstructor (optional - string type): functionName
pahoMqttPointName (optional - string type): pointName
