[Nut-upsdev] How do I approach this problem?

[Jeff Cunningham]

I'm having a problem that I hope those with greater experience might 
have some ideas on.
I live up in the mountains where the power is ill-conditioned. 
Transients which would cause a computer to reboot occur on a daily 
basis. Power failures are frequent and can last anywhere from five 
minutes to five days. I have all my computers on UPSs so the first two 
problems are solved. I have a generator for the third problem. The 
difficulty I am having is with the power failures that last long enough 
to drain the battery on the UPSs.

As this would damage the batteries, I programmed the UPSs to shut down 
their respective computers after roughly half the life of each UPS 
system's capability. The problem that remains is that I would like to be 
able to have these automatically restart once the power comes back on. 
For one thing, I have one computer hooked up to sensors taking data that 
I would like to be off-line as little as possible, and I have another 
which serves this data to the outside world when possible.

This is a low-budget operation, so buying bigger UPSs or auto-generator 
systems is not an option. Is there any way to have the UPS restart my 
computers once it knows its back on live power?

I am using nutups to communicate with the UPS on the computer hooked to 
the sensors. I have a tripplite on the other main computer and am using 
their package. Both are Linux computers.

Your help would be greatly appreciated.
