incompatible with firmware 2009 about aerocli HOT 8 OPEN

I have firmware 2009, and it is working. Are you sure you are using fw 2009?
Please put the aerocli output here so that I can check

from aerocli.

I am definitively on firmware 2009 (just checked with the aquasuite on windows), and by running aerocli I get:
Unsupported firmware 2009
failed to poll: (null) (Bad file descriptor)

And yes, I have the correct udev-rule set.

Oh, perhaps I should mention that I needed to use gcc-5 to successfully compile, my system's standard compiler gcc-7 (and gcc-6 also) threw some errors while compiling aerocli.c. I can post them if it helps.

For the compilation, it is because my fixes are on the devel branch, not the stable branch.

For the error, I think you didn't compile the correct branch... after checking, you should also use devel branch.
This branch is not perfect yet (one annoying bug that prevents reading names etc because of a design flaw... it need a rewrite of the reading part of the code, but I do not have time to fix that and nobody did)

Ah, yes, it really seemed that git clone got the wrong branch. I re-compiled with the devel-branch and it is mostly working right now (the necessity to run autoconf/autoreconf before configure might be a good thing to put in the INSTALL). aerocli doesn't get the CPU temperature and my installed aquastream pump, but the sensors are there:

cpu temp is purely software: this is the PC that sends the cpu temps to the aquaero.
This is not supported by aquaeronix.
For the aquastream, never tested since I do not have one. At least it is detected, but the decoding is not correct.
If you want, you can pass the -D option to dump the data to a file of your choice. And then guess the offset if you know the expected value (using windows)

from aerocli.

The aquaero has a temperature sensor for its own cpu, that's what usually is displayed for the CPU temperature. It does not correspond to the computer's cpu temperature. This is how it looks for my other rig with an aquaero that has an older firmware (not sure which exactly):

CPU Temp: 41.03 °C
(lmsensors reports: Physical id 0: +26.0°C)

The aquastream is not that important, but since it reads "10000Hz @ 0.00V", I agree that the decoding is off somewhere. BTW, calling aerocli with the -a flag results in a segfault.

strange... I do not see any cpu temp in windows nor in the aquaero display.
They may have removed it in firmware 2009.

For the crash, this is because of the usb reports not being read for names.... something most likely changed in the kernel making the issue worse. This means that aquaeronix must be updated to fix the report names reading.
This makes the dump feature painful to obtain (I needed to retry several times)

from aerocli.

They really might have removed it, it's not there in windows here, either. Can't confirm for the display as it's the "light" version of the aquaero (PCB only).
BTW, besides the call of aerocli without options (or -o default) nothing much works. The export function is what I currently miss most, I use it to feed a rrd database.
