Parameter MainTopic

Default Value: watermeter

MQTT main topic, under which the counters are published.

The single value will be published with the following key: MAINTOPIC/NUMBER/RESULT_TOPIC

With:

  • NUMBER: The name of the value (a meter might have more than one value). The names get defined in the analog and digital ROI configuration (defaults to main).
  • RESULT_TOPIC: Automatically filled with the right name, eg. value, rate, timestamp, error, ....

The general connection status can be found in MAINTOPIC/CONNECTION. See MQTT Result Topics for a full list of topics.

!!! Note The main topic is allowed to contain / which can be used to split it into multiple levels, eg. /basement/meters/watermeter/1/ if you have multiple water meters in your basement.
