Hi guys, I'm brand new to Node Red and learning linux command line on the fly. I have come up with a command that returns my CPU Temp. I'm trying to implement this for an ARM64 CPU piece of hardware.

After having weird results in Node Red I decided to test this same code on my laptop running Ubuntu 20.04 with Node Red as the local host and get the same result of 0 C. This is just the start of a dashboard with lots of hardware info but I've been stumped since this works just fine when I enter it in the shell on two different systems, both debian based. Both terminals give me somewhere between 30 - 45 C which I feel is fairly reasonable.

My gut says Exec Node doesn't recognize the cputemp variable?  
`cputemp=$(</sys/class/thermal/thermal_zone0/temp) && echo "$((cputemp/1000)) c"`

I've also tried just to read the raw data and this does work in Exec Node:  
cat /sys/class/thermal/thermal\_zone0/temp

Here is my Flow:

Somehow you have ``` backticks at the end of it that is messing up importing.  
FIXED:

I believe your issue with the exec node is caused by the use of input redirection and/or trying to use Command Substitution.

Digging deeper now.

The first issue you should tackle when using node-red's exec node is to break up any piped and/or chain commands. As the last command executed will give you your **Standard output** and **Standard error**.

I'm going to walk you through how my brain tries to find a bug. I'm sure your higher up in skill than how I'm going to answer this issue. However I'm writing this for every one from the lowest level of understanding up.

In the exec node I changed:

```auto
cputemp=$(</sys/class/thermal/thermal_zone0/temp) && echo "$((cputemp/1000)) c"

```

to

```auto
cputemp=$(</sys/class/thermal/thermal_zone0/temp)

```

and I get no error.

As with your original command we get 0 c I think to myself "what is the value of $cputemp".  
so I changed the exec node to:

```auto
cputemp=$(</sys/class/thermal/thermal_zone0/temp) && echo "$cputemp"

```

and I get an empty string. I try the same/above command in terminal and get a value of **40780**  
so I think the exec node is not able to use input redirection

So I try calling cat in the exec node:

```auto
cputemp=$(cat /sys/class/thermal/thermal_zone0/temp) && echo "$cputemp"

```

and I still get an empty string. I also try the above command in terminal and get a value of **40723**

So my brain now thinks: "OK the exec node does not support Command Substitution" now what do I do.

Well as you stated the exec node does output the raw value for cpu temp with:

```auto
cat /sys/class/thermal/thermal_zone0/temp

```

I would just do the math in a function node:

HOLD UP!!!!!!!

old-style backquote method of command substitution works. Go figure.  
[When the old-style backquote form of substitution is used, backslash retains its literal meaning](https://www.gnu.org/software/bash/manual/html_node/Command-Substitution.html)

So I use:

```auto
cputemp=`cat /sys/class/thermal/thermal_zone0/temp` && echo "$((cputemp/1000)) c"

```

in node-red exec node and I get **42 c**

However I then tried input redirection:

```auto
cputemp=`</sys/class/thermal/thermal_zone0/temp` && echo "$((cputemp/1000)) c"

```

and it does not work.

Oh the joy of bug hunting.  
  
  
  
  
Note: the command that works

```auto
cputemp=`cat /sys/class/thermal/thermal_zone0/temp` && echo "$((cputemp/1000)) c"

```

Does not support decimal places (floating point) I would use the function node version I created in the post above or use printf floating point precision if I need greater precision.

example of working command using printf:

```auto
cputemp=`cat /sys/class/thermal/thermal_zone0/temp` | printf %.2f "$((10**3 * $cputemp/1000))e-3"

```

I haven't tried it but perhaps it would be better to use a file in node to read it rather than cat.

You are Correct! the file method works just fine......

Better to use a all node-red implementation than using exec node for this one.

Sorry I get so wrapped up in exec node I could not see the obvious in front of me. Thanks @Colin

I'm way more comfortable in bash and command line than I am in JS so I became good friends with the exec node early on 😛

I tend to use allot of command line calls in my flows 🙂

The original command from @MrRum likely did not work as it uses shell features. If insisted, it should work if it was a separate script to exec. Let's say `read_temp.sh`:

```auto
#!/bin/bash

cputemp=$(</sys/class/thermal/thermal_zone0/temp) && echo "$((cputemp/1000)) c"

# or alternate easier to read version
cputemp=$(</sys/class/thermal/thermal_zone0/temp)
echo "$((cputemp/1000)) c"

```

Change the script permissions to executable:

```auto
chmod u+x read_temp.sh

```

Then running `read_temp.sh` in an exec node.

...but if course this maksa no sense as the Node-RED version is so much cleaner. 🙂

Thanks @meeki007, @ristomatti, Colin for the help. As you can probably tell I don’t have a CS background but I’ve been on the hardware side for many years and I’ve hacked other things together in the past but not using Node Red or Linux.

Since the primary function of the device is to collect data / protocol converter I don’t want or need the dashboard to be super flashy or resource intensive, so the simpler the better.

I definitely like the simple flow and file suggestion which if needed I could pull later for a snap shot if there is an issue.

Thanks again and I’ll work on adding the other HW info and will post when I have a more comprehensive flow. Cheers!

So here is what I got so far. I haven't figured out how I'm going to add Send and Receive Network Traffic yet.

Any suggestions I would greatly appreciate it. I loaded the LXDE desktop on this device and ran gnome-system-monitor and the Node Red Dashboard Outputs for CPU0/1, Mem, and Disc are extremely close.

I will also be modifying this for the QuadCore version of the IOT2040 as well.
