[Nut-upsuser] How to delay computer reboot until battery has recharged?
Hello all, I'm using Nut quite happily with my Powerware 9125 and 9115 UPSs. I'd like to delay restoring power to the computers after a loss of power shutdown until a reasonable battery charge has been restored, to prevent repeated shut downs in a brown out or storm situation. I know I read somewhere how to do this months ago, but now that I need to implement it, I can't seem to find the documentation I recall. Can anyone point me in the right direction? Any and all hints/tips/pointers will be appreciated! Michelle Franz

But the ups have a 'Utility Return Stabilization Delay' that can be set between 0-18000 sec. And also 'Minimum Battery Capacity for Return' ranging from 0 to 100%. The current value is contained in the 'extended limit block' but the driver is not reading the info from that at the moment. It only reads the number of minutes it will remain on after a LowBatt alarm has been given for the full rated load from that block. So a quick fix is to hook it up to a Windows machine running the software from Powerware and change this values. I have many things on the to-do list for the driver, and this is one. What NUT version are you running ? Is it a binary dist or do You compile it from source ? It is easy to make it read the info, but a little dangerous to start setting parameters. Regards Kjell
