how to check the data coming from the mysql database and analyze them using node red while establishing daily peaks corresponding to the type of ph collected
Welcome to the node-red community. Generally it’s better if your title explains a little about your problem eg “daily max from mysql” rather than “i have a problem”
It’s more likely the catch the attention of any mysql experts and is also more useful to anyone searching the forum for help in the future
Hi. I have updated your topic to help those who know mysql find your topic.
Ps, it's fairly impossible to help if you don't show what you have done, where it fails, your table names, your table structure, a sample of data etc.
