No problem :)

The ipdevpoll `inventory` job needs to run successfully for the device
to be identified first (and, unfortunately, the sensor may not be added
on the first inventory run. The first run sets the device type, so that
the sensors plugin has that value available only on the second run - and
by default, successful runs are on 6 hour intervals).
You should see all succesful/failing jobs in the job status box in the
ipdevinfo page of your sensor device (just search for it in the
navbar). If the jobs aren't running at all, are you sure ipdevpoll is
running?
You can also run these jobs manually from the command line:
ipdevpolld -J inventory -n <name-of-sensor-device>
Run it twice, and see if the sensor appears in ipdevinfo. Once it does,
the 1minstats plugin should collect data from the registered sensors
every 60 seconds.

I think it should be fine; as long as you do not provide a precision
value in the sensor record, the string would be sent raw to
Graphite. SNMP doesn't really have a data type for floating point
numbers, so there are usually only two ways to go about this: Use
strings, or provide a scaled value.
