  We are trying to build our Enviro DIY station and we are receiving an error message I have included a link to a Google Doc explaining what is happening. https://docs.google.com/document/d/1xJArzqxf2qV04srhP44BCOmxX2UbeiryKiBTQ6nuIMg/edit?usp=sharing

  How and when did you download all of your libraries?

  We downloaded them on Dec. 1 2025 and we had to let Penn State IT department download them because I am using a PSU computer. I have a feeling that PSU firewall or IT security may be part of the issue.

  From your error messages, it looked like you have mismatched versions of libraries. I’m not sure how permissions are set up on your PC, but typically the Arduino libraries would be stored in a personal user folder that you could change at will.
