Can't get plasma-disks and hddtemp working, and there are also DoubleCommander issues

Welcome Everyone,

I’m newbie to NixOS. Installed it about two weeks ago on metal but played in VM before that flew times.
I slowly coming around with stuff there are things I can’t figure out or find searching on web so I hope you can provide some advise here…

I can’t get Plasma Disk displaying smart status where GSmartControl displays all except NVMe disk
I got smartmontools, gsmartcontrol and libsForQt5.plasma-disks declared as system packages, played with smartd but no luck.

   services.smartd.enable = true;
   services.smartd.autodetect = true;
   services.smartd.notifications.x11 = {
       enable = true;
       display = ":${toString config.services.xserver.display}";
   };

HDDtemp works when run from terminal sudo hddtemp /dev/sda but can’t get smartd working so I can’t use it in conky. Tried to read from it using nc but got bunch of errors as return.
EDIT: Wrong piece copied below:

    hardware.sensor.hddtemp = {
        enable = true;
        drives = [ "/dev/disk/by-path/*" ];
        dbEntries = [
           "INTEL SSDSC2KB240G8" "190" "C" "INTEL SSDSC2KB240G8"
           "CT1000MX500SSD1" "194" "C" "Crucial CT1000MX500SSD1"
           "WDC WDS240G2G0A-00JH30" "194" "C" "WDC WDS240G2G0A-00JH30"
       ];
    };

And there is Double Commander… will not open/mount unmounted drive like on any other distro. It gives me “Disk is not available” error when trying to open. I need open the disk from KDE’s system tray or from Gnome Disk Utility.
It also doesn’t displaying majority of file types even when xdg.mime.enable = true; is enabled.
When run from shell it only complains about Breeze theme missing.
