Where does "print" print to?

[hafniumzinc (T)]

This question was asked here by the guy who’s developing a whole bunch of openHAB specific blocks for Blockly, but I couldn’t see an immediate answer…

Extending Blockly with new openHAB commands

I have a question I stumbled over the following print-block: [image] which generates print(‘abc’) The help tooltip says “Print a message on the console”. Which console is meant here? What is it meant to be used for? As the rules are run on the server side, wouldn’t the log-block enough or do I miss something?

Actually, found an answer

Actually yes there is - it will print to stdout and you can likely only see it when you run openHAB directly in the foreground (not as a daemon with systemd or similar). You can also see them appearing even if you’re not “tailing” your log with log:tail - and it doesn’t pollute the logs while you’re debugging.
