I have been struggling with this as well. Basicly, you have make sure your output of the output script looks like
Device Temp(°C) Temp(°F)
[image: green] Cpu1 33 91 [image: green] Mainboard 35 95
I've ended up with the following, using lm_sensors input. #!/bin/sh
COLUMN=temperature # Name of the column TEST=temperature
echo " $BBTMP/$MACHINE.temperature.$$"
Do whatever you need to test for something
As an example, go red if /tmp/badstuff exists.
ENV_CELSIUS=$(sensors |grep 'CPU Temp'|awk '{print $3}'|sed -e 's/+//' -e
's/°C//' -e 's/..$//')
ENV_CELSIUSMAINB=$(sensors |grep 'M/B' |awk '{print $3}'|sed -e 's/+//' -e
's/°C//')
ENV_HIGHWARN=38
ENV_HIGHPANIC=42
ENV_CPU="Cpu1"
ENV_MAINB="Mainboard"
$AWK -v CELSIUS=$ENV_CELSIUS -v HIGHWARN=$ENV_HIGHWARN -v
