Probe device

Just type this:

# ./check_neon.py --host=10.0.10.81
NEON OK - temperature is 21.14 C, humidity is 30.52 %RH
| humidity=30.52;20:80;20:80 temperature=21.14;25;25

We check temperature and humidity always together. If you to not set critical or warning thresholds we'll use the Hi- and LoAlarm from webinterface

Probe with own thresholds:

# ./check_neon.py --host=10.0.10.81 -c 20
NEON CRITICAL - temperature is 21.15 (outside range 0:20)
critical: temperature is 21.15 (outside range 0:20)
critical: humidity is 30.33 (outside range 0:20)
| humidity=30.33;20:80;20 temperature=21.15;25;20
