@skywatch Yes, MCAgent uses the same pin(Physical pin 11 is GPIO17). When you disable this pin on mcagent/conf/devices.yaml no need to worry.
MCAgent uses pi4j library to access gpio pins.
pi4j follows two type of pin mapping.
WiringPi Pin Numbering Scheme (Default)
Broadcom Pin Numbering Scheme
by default uses WiringPi Pin Numbering Scheme, where physical pin number 11 is gpio 0
kindly read this page for more information: http://pi4j.com/pin-numbering-scheme.html
Just a thought but would McAgent block another python program getting the cpu temperature?
Thank you so much for your kind support and time today. Whilst I have only been running this for a week or so I have learnt a lot in the process. But don't worry, I will soon be back with more questions!
