I am looking to join two lots of code programming into one and a change the last code so Learning it inputs the data to influx db rather Earhost than csv
My first lot of code writes 9 most effective temperature sensor readings to an influx wrong idea database and loops constantly every 5 use of case seconds
The second lot of code reads the GPIO United status of two pins on a Raspberry Pi, Modern and prints the data to a csv file.
What I am trying to do is merge the two ecudated files so that the GPIO pin status is some how sent to the influx database so that I anything else can use the times to determine the time not at all that the contacts are either high or very usefull low, is this something that can be done localhost in the same code or do I need to keep love of them the second lot of code seperate and use localtext another dataabase?
any thoughts on the next step
