...voltage is less than 85 volts, it will trigger ONBATT event from NUT. Is there a way in NUT we can change the threshold from 85 volts to a lower voltage like 40 volts? It might be possible with upsrw - try modifying "input.transfer.low" and "input.transfer.boost.low". However, 40V to 110-120V is a long way to boost. Is this UPS rated for such a wide voltage range? You could also check for sensitivity settings. I don't know about the 3S in particular, but theoretically, usbhid-ups supports those sorts of settings. -- Charles Lepple clepple at gmail

Hello, We have an Eaton 3S 550 UPS using NUT tool to send power loss event. By default the power voltage threshold is set to 85 volts. If the voltage is less than 85 volts, it will trigger ONBATT event from NUT. Is there a way in NUT we can change the threshold from 85 volts to a lower voltage like 40 volts? We were trying to change ups.conf to modify the output of upsc ..., but looks like it

Hello Charles, Thank you so much for your reply. Yes. 40v was too low. In windows, those range started from 76v, 85v, and 96v. Just tried upsrw command to modify input.transfer.low and input.transfer.boost.low. There were some error messages returned. Tried another one battery.charge.low and it returns ok. $ sudo upsrw -s input.transfer.low=70 -u * -p *...

...ossibility to give a full path to upsstats/upsimage. This comes in handy when you call the CGI stuff by SSI from a parsed HTML page and want links to go to that HTML page and not the CGI:s directly. And possibly other uses. - upsimage: * Fixes the battery.voltage graph. It was hardcoded to 40V or something, looked outright ridiculous with 420V battery voltage ;) * Improves logic on figuring out min/max values to cope with 400V nominal. And probably more stuff that I have fixed while stumbling around in the code. To fix before commiting: * There are a couple of FIXME:s that I stu...
