NUT not reporting APC smc1000i-2u input.voltage

[balla]

I'm on core-13.0-U2 but got the same behavior when I was on core-12 too. The problem is that if I connect apc powershute on windows then I'm able to see more variables compared to truenas core and NUT-hidusb driver.

Code:

I can live without most of the missing vars but input.voltage would be useful to have. Any ideas how to make this work? I have also tried running apcupsd on opnsense and use the NUT-apcupsd driver on truenas but it does not change anything. I have seen others posting input.voltage for this ups on Linux so I assume NUT have the support but something is not configured as I want it on truenas. Any ideas where to look? I can't be the only one using this ups :)
