G'Day all!
I am SSH'ing to other pi's to get their CPU load and Temp
It runs and gives output in a shell however node-red isnt seeing it because its not stdout
it runs locally fine.
ssh -l pi 192.168.2.246 top -d 0.5 -b -n2 | grep "Cpu(s)"|tail -n 1 | awk '{print $8}'
when run over SSH in node-red it returns ""
Any hints or ideas?

edit: I thought id try node-red-contrib-interactive-ssh
Its suppose to return an string of the output but it returns a buffer with nothing I can see useful?
