-- `OCTOPRINT_APIKEY` - OctoScreen expects an [API key]( http://docs.octoprint.org/en/master/api/general.html) to be supplied. This API key can be either the globally configured key, or a user-specific one if “Access Control” is enabled.

The file path should be a fully qualified path and not only include the path to the log file, but the name of the log file as well (eg `/home/pi/logs/logfile.txt`).  The log file is appended to and is never automatically truncated, and will grow over time.  If you turn log file logging on (by specifying a path), be sure to turn it off (by setting the value to "").
