To get the avg CPU you can use
top -n 1 | grep "%Cpu"
or
mpstat (Available with the LE system-tools addon)
However, they are the AVG. To do what I think you are after, you'll need to check each of the 4 CPU's in order, as 3 CPU's could be low whilst only one was at 100% and causing an issue. This would give an AVG of ~25%
If you still need the information about individual CPU percentages then /proc/stat will give you that. It's a bit confusing, and you'll need to adjust the figures to get an overall value. Personally I wouldn't bother as the temperature is more important than CPU load.
jane_t the add-on that you've made is great!
But when I shutdown my Pi, sometimes your script is still running and the Pi is unable to unmount the /strorrage partition at some shutdowns/reboots.
Maybe you can build something in the code, that makes the script stop running when the Pi shuts down or reboots?
Thanks a lot!
I've never had a problem with unmount or shutdown with the addon running - there is nothing in the code to hinder that.
However, yes the fan will continue to run once the system has shutdown - (Also before LE has booted). Not too sure if the code can be reversed so that this doesn't happen but as this was their first attempt at writing an addon, I think we have to live with the results for the moment.
I will take a look at it, but it happens after installing this addon.
I let you know

Problem found, I have enable the Hifiberry settings in the config.txt and the problem is gone. So if I shutdown LibreElec only the LibreElec logo/version appears and not wich deamon is closed down. 
So, i tried the fanshim addon, installed it, rebooted, etc... all according to the howto, but it doesn't seem to be working? But i think the shim isn't connecting to the headers properly? When i push the shim towards to power/hdmi ports the led goes on (blue or green, super bright) but the fan never stops.
Rebooted mulitple times, anyone have these issues? and/or know how to fix them?

I have the same problem. Since i didn't succeed, I tried a completely new installation of libreelec, kodi, raspberry tools and fanshim on another sd. But still no succes, the fan is just running 100% all the time. I eperimented with differnen on/off temperatures, leds on/off seting but the addon seems to do nothing.
I am curious if there has been any success to this, as I recently got the Cana Kit Pi 4 with the fan on and would love to have a way to auto turn it off or even manually through Kodi.
It doesn't make sense to add questions to a solved thread. All users with open questions should open a new thread.
