OK, i suppose that this issue will be solved when all the liebert devices will be moved in the liebert-hid driver, in the future.

Please find in attachment the hid report descriptor : there are several Charging/Discharging fields.
I'm wondering if it gives the status of the different (additional) battery composing the system ?

Is there a list of all official NUT names (i haven't searched yet) ?

Cheers.
