(How embarrassing.)
I already had most of that flow already. I just hadn't added the GUI.
One way I did it was:
df -h /dev/sda1 | grep / | tr -s ' ' | cut -d " " -f4
But that shows me the remaining spavce - I think. I didn't know the --output=used bit then.
And the way I did it last night was:
df --output=used /dev/sda1
(but then needed to do work on the output with other nodes.
Sorry guys.
It is called C.R.A.F.T. disease.
I'll let you work that out.
then just feed into the gauge (as it will cope with simple text.)
@dceejay Yeah, oops. Silly me.
Oh, not to sound petty.
Ok, so that part works.
It is/seems silly having that and not having a threshold above which it alerts me.
So I send the output to a switch and switch if the value > (what ever)
So I am guessing I will need a function node in there with msg.payload = parseInt(msg.payload) in it.
