main page = status
config page:
-nut status : enable/disabled

    nut mode : standalone|netserver|netclient
    if netclient mode

ask for SlaveUPS "UPSNAME@IP" and SlavePass ""
set Master as no when saving

    if standalone or netserver

either use default value for NUT device, or allow to set them
${nut-driver@UPS }{Model} usbhid-ups you can use a drop-down listing all the device rpm -ql nut|grep /usr/sbin
${nut-driver@UPS }{Device} auto
only if Model genericups:
${nut-driver@UPS }{Type}
${nut-driver@UPS }{mfr}
${nut-driver@UPS }{mdl}
on saving set nut{Master} to yes if mode standalone or netserver
if mode=netserver set nut{access} to private otherwise set as localhost
run signal-event nut-conf

if enabled the status page could return upsc UPS@localhost, or if slave upsc UPSNAME@IP
if netclient set nut-monitor status to enabled and set status disabled to nut-server and all existing nut-driver@* ( we can set multiple via cli, so a loop would be great there)
if standalone|netserver then enable all nut related service if nut enabled
if nut disabled then set all related services to disabled
