It is in the garage with the NAS, a router and printer and an obsolete Pentium 3 taking up valuable space. BJ I wasn't meaning to imply the services weren't valuable, I just wanted more info. I think this is a good feature request, though since it is specific to one UPS brand perhaps a third-party app would be would be the right way to do it.

Of interest, one facility on my other UPS is that when on battery power only, the signal to shutdown can be sent to the PC/equipment/router etc after a defined number of minutes.
I set mine to 1 minute, but could be 2, 3 etc. The ReadyNAS equivalent option is between 10 and 80 % (and Auto which I believe is 60%) for the 'Shutdown Threshold'. If I set this to 80% say, then when the battery gets old it MAY not hold at 80%. There is NO INDICATION (as far as I can see) that the shutdown threshold via ReadyNAS is ONLY when the UPS is on battery power. So if there was a problem and the battery was 'low', on reboot of the ReadyNAS would it go and shutdown (even with mains good), just because the level is below the threshold. I think what I am asking is "Does the ReadyNAS know that the UPS is 'recovering' and wait for the level to go ABOVE the threshold before implementing the test for being below the threshold?". Hope this makes sense. I cannot trust something until I understand how it works in general, so that I can get it to work for me, as I want it!
