The temperature path to use, e.g. */sys/class/hwmon/hwmon2/temp1_input* instead of one in */sys/class/thermal/*.
This can also be an array of strings. In this case, waybar will check each item in the array and use the first valid one.
This is suitable if you want to share the same configuration file among different machines with different hardware configurations.
