Hi, Installed following the readme instructions with default parameters. Thinkfan.service throws the following error on start:

ERROR: Unhandled std::bad_optional_access: bad optional access.
errno = No such file or directory.

Although it works fine on the command line with:

thinkfan -n

This is happening on a Thinkpad T480 on Archlinux.

thinkpad.yaml

sensors:
  - tpacpi: /proc/acpi/ibm/thermal
    indices: [0]
    max_errors: 10

fans:
  - tpacpi: /proc/acpi/ibm/fan
    max_errors: 10

levels:
- [0, 0, 50]
- [1, 45, 65]
- ["level auto", 60, 85]
- ["level disengaged", 80, 255]

This is probably related to #206...

I've fixed an issue with tpacpi sensor initialization in the latest master, could you please build that and report whether it fixes your problem?

[ciminoV]

Problem fixed! Thank you
