> Are there any plans to allow us to specify UPS variables in ups.conf, eg:

We already support this (as a hidden feature) since nut-2.4.0, where  
it is possible to set

     default.<variable> = value (default to value if UPS doesn't report this)
     override.<variable> = value (same, but override if reported by UPS)

But most likely, this is not what you need.

You probably missed the man page for the usbhid-ups driver. See  
'offdelay' and 'ondelay' under EXTRA ARGUMENTS in 'man 8 usbhid-ups'  
which are meant to do what you want. Using the  
'(default|override).ups.delay.(start|shutdown)' mechanism might also  
work, but this is not recommended.

I doubt it.

This most likely doesn't work, since the changed values of  
'ups.delay.start' and 'ups.delay.shutdown' won't stick between  
invocations of the driver. Only if you keep the driver running and  
send the instcmd 'shutdown.return' this might work, but this is not  
what happens if you call 'upsdrvctl shutdown' (where the driver is  
restarted with the -k flag). You *must* use ondelay and offdelay
