Integration problems with Dell computers

[myriaxis]

Hi,
I have two Dell servers (PE T110ii and PE R540) that I would like to power on/off from HA via IPMI.
I installed your IPMI connector via HACS and I can see it in the /homeassistant/custom_components folder.

For the PE T110ii, I managed to add it as a device.
Using an HA script, I can power on, power off, but soft shutdown does nothing.
Also, the device switch is unavailable most of the time.
If I use ipmitool from a windows command prompt, I can issue a soft shutdown successfully.
What should I do to use the soft shutdown?

For the PE R540, I can't add it as a device.
If I use ipmitool from a windows command prompt, I can get the chassis status.
So, the server responds to ipmi commands, why am I not able to add it?

Please help,
