Starting again after setting aside my energy monitoring project in 2015. I’m afraid I am having a great deal of difficulty making OpenEnergyMonitor work for me. For example I can’t find a document anywhere that says how to reload emonhub.conf after making changes.
But I finally figured out how to do it by looking at the source code for emonhub.py. The answer is emonhub.py looks for changes to emonhub.conf in its main loop and reloads this file whenever any such changes are detected.
Hope that helps another newbie like me.
