Need some help shifting over to MQTT for my solar power system. following sketch on github. I have some understanding connecting thru MQTT but clueless on publishing data. an example for 1 of the voltage readings would be helpful so I can build on that.
Thanks

Anyone have a clue why this error message is coming up? If so, is there a fix? I just finished uninstalling and installing Arduino because of invalis library errors then returned the libraries necessary to upload the code for my PLduino.

This report would have more information with
