What log file is it referring to so I can troubleshoot?
This what a discovery of the device shows:
I see the error:
Sensor fetched value: 10
Error discovering sensors module for 10.100.30.208. DivisionByZeroError: Division by zero in /opt/librenms/includes/discovery/functions.inc.php:959
I assume you either set it to 1 if you want the value, or something else if you need to ‘scale’ the value … (ie if the raw value is say 157 which equates to 15.7 degrees then set it to 10)
