null values in custom logs

From Cumulus MX version 3 build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since, and has recently released Cumulus MX version 4. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

null values in custom logs

Post by HansR »

I am working on null values in custom logs and for that I created a Soilmoisture customlog:

      Then I disable the SoilMoisture1 sensor
      In the ExtraSensors log it correctly becomes null (after restarting CMX):

          But the output of the customlog then becomes:
            Schermafbeelding 2025-01-16 064821.png
              I think the customlog should log the zerostring just as it does in the ExtraSensor log. That would be consistent.
              What do you think?

              Or should I make the webtag:

              Code: Select all

              <#SoilMoisture1 nv=''>

              Nearly, it should be nv="". The nv= accepts a string, so "null" may be valid for say SQL inserts, but not for this CSV usage, you want an empty string.

              BUT I just checked, and the token parser does not accept empty strings! Fixed for the next build :(
