Logger Configuration - Supergiovane/node-red-contrib-knx-ultimate GitHub Wiki

Logger

The Logger node records all telegrams and outputs it in an ETS bus monitor XML compatible file.


You can save the file on disk or send it to an FTP server, for example. The file can be then read by your ETS, for example for diagnostic or for a replay of the telegrams.
The node can also count telegrams per second (or any interval you want).
Examples are here.

MESSAGE OUTPUT FROM THE LOGGER

PIN 1: XML ETS bus monitor compatible file File

You can use a file node to save the payload to the filesystem, or you can send it, for example, to an FTP server.

msg = {
        topic:"MyLogger" 
        payload: "CommunicationLog xmlns=http://knx.org/xml/telegrams/01 Telegram Timestamp=2020-03-27T07:32:39.470Z Service=L_Data.ind...." (A String containing the XML file)
    }



PIN 2: KNX Telegram Counter

Each count, the node will emit a telegram like this:

msg = {
        topic:"",
        payload:10,
        countIntervalInSeconds:5,
        currentTime:"25/10/2021, 11:11:44"
    }
