@temp An example command for a shell sensor for power extern…
/opt/susv/susv -status | grep Extern | cut -d “:” -f2 | cut -d " " -f2
your command | filter this output (your data) on line containing Extern | filter this line containing Extern and separate this line using deliminator : , return field 2 | filter this and separate this line using deliminator “space” : , return field 2
This will return number 1459.00 which should go into a variable. You could take out the decimal with another cut.
There are probably other ways to do this but this is my suggestion. Hope it helps.
