Does anyone know how to use sensorsd? The documentation is pretty poor. I
just installed a snapshot and would like to test it out. I have
uncommented /etc/sensorsd.conf so it now looks like this:

hw.sensors.3:low=4.8V:high=5.2V
hw.sensors.4:low=11.5V:high=12.5V
hw.sensors.7:high=50C
hw.sensors.8:high=60C
hw.sensors.11:low=3000

So far all I get is:

$ sensorsd
sensorsd: no sensors found

Thanks for any pointers.
