Raspberry Pi with Node-RED Tutorial #5 – backup and import a project

How you read out the CPU temperature, load and the free memory.
And how you make a backup with the export and import command.
By the way you can download my example from here:

Finally, a Node-RED video that doesn't pair a $50 Raspberry Pi with a $200 power supply 😀💐

raspberry pi : linux commands shown at 1:31
vcgencmd measure_temp
top -d 0.5 -b -n2 | grep "Cpu(s)" | tail -n 1 | awk '{print $2 + $4}'
free | grep Mem | awk '{print 100*($4+$6+$7)/$2}'

For node red, add dashboard nodes, so you can build the webpage, use node red menu, far right eg 3 horizontal stripes,
choose option "manage palette", tab "install", enter "dash" in search (no quotes), install node-red-dashboard
(before building/importing the example)

Nice, how can i set up this for different Raspberrys ?

(1:00) Why the CLI command shows 2.8% but the CPU Load on Rasperry Pi OS is showing 10%?

Interesting your channel and your projects, greetings

Is it possible that there is a mistake in it for the memory available?
In your code, there is this : free | grep Mem | awk '{print 100*($4+$6+$7)/$2}'
On my RPI, that results in 173%? Isn't it MB?
