ambient_ipmitemps not working, stuck at 20 degrees, not updating! [R710]

[PbtServers]

my server CPU is at 47 degrees or so and the fans are not spinning, also my hard drives are at 52 degrees at maximum and r710 fans not spinning also...

[PbtServers]

I cannot use this script as it is right now because it makes my whole server super hot, it just disables the fans no matter the temperature of the components!

Sorry, missed this bug report - maybe this time I've configured github alerts properly.

What hardware are you on? The latest 2 commits for README.md tells you what you need to test, and maybe gives a tiny hint on tuning. Unfortunately all the poweredge generations are different enough, as are the hardware options that you may have put in them, that I can't really generalise very well. You will be stuck tuning it and you'll have to understand the logs yourself.

With that one small snippet of log, I see that the fans should be spinning, but maybe you need to get it to bump up the demand using one of the many levers the code has. My own server has these logs currently, for reference:

and is alternating around low to medium-low speeds (er, let's say 3400-3600 RPM).
