=head1 NAME
usb-wde1 - Munin plugin to report usb-wde1 temperature and humidity data
=head1 CONFIGURATION
The plugin offers two modes: temperature and humidity graphing.
Symlink usb-wde1_ as "usb-wde1_temperature" and/or "usb-wde1_humidity".
=head2 EXAMPLE CONFIGURATION
[usb-wde1_*]
env.logfile /var/spool/usb-wde1/usb-wde1-last
env.host_name House
env.sensors 0 1 7
env.sensor0 Living room
env.sensor1 Kitchen
env.sensor7 Outside
Warning/critical values for all sensors:
env.warning 10
env.critical 5
Warning/critical values for single sensors:
env.sensor7_warning 40
env.sensor7_critical 50
