I did install fw-fanctrl because that one comes with ectool and can do a little more with it:
cd ~
git clone https://github.com/TamtamHero/fw-fanctrl
cd fw-fanctrl/
sudo ./install.sh
Now you’ve got both ectool and fw-fancontrol installed and can view some values as well as modify fan curves and the like.
ectool requires elevated privileges, so to test
sudo ectool battery
will show some battery data.
AFAIK, it won’t work with secure boot enabled. There’s work underway to integrate it into the kernel, but I don’t know when that will go public.
