      @fjmp24 said in Notification: UPS ups battery is low:

      • runtime is equal to 0:01:41
      • battery charge is equal to 19%
        Why doesn't it send the message when runtime is equal to 0:05:00 ? I set override.ups.delay.shutdown = 300

      NUT initiates a shutdown when the UPS declares that the battery is low (LB). The decision regarding a low battery is made by the UPS itself. Some UPSs have configurable LB levels, and some have fixed LB levels. If your UPS has a configurable LB level, this is configured by the battery.charge.low variable. 20% is a common default.

      When performing a shutdown, one of the last steps is for the OS (pfSense) to instruction the UPS to cut the power. After receiving that command, the UPS waits a short period of time before it actually turns off the power. The purpose of this delay is to allow the OS to complete its shutdown before power is cut. Some UPSs have configurable delays, and some have fixed delays. If your UPS has a configurable delay, this is configured by the ups.delay.shutdown variable. 20 seconds is a common default.

          Hi,

          I did a test to see if my UPS is working properly. I could see that it wasn't :-(
          The UPS cuts the power very quickly (about 1 minute), which means, for example, my NAS doesn't have time to shut down properly.
          My setup was working before. I updated pfSense. The problem might be coming from there.

            @fjmp24 How old is the battery? Have you done a calibration test?

              @dennypage I changed the battery this year. I don't understand : "Have you done a calibration test" ?

                Most UPSs have a "battery calibration test", "runtime calibration test", etc. You are looking for a test that runs the load off of the battery (without cutting mains) to see how the battery behaves under actual load.

                Btw, you should remove the ignorelb directive from the Extra Arguments to driver section. Unless you have a very old UPS that signals low battery whenever the UPS is on battery. You almost certainly do not have such a UPS.

                    Yes, but that may be completely inaccurate, especially with bad batteries. That's why you run a calibration test.

                      @dennypage I can't run the test. But there's an automated system that does it every week. I tested it without override.ups.delay.shutdown. My UPS shuts down after 30 seconds, compared to 1 minute with the override.ups.delay.shutdown.

                      I don't understand anything :-((

                        I didn't say you should remove the override.ups.delay.shutdown directive, I said you should remove the ignorelb directive.

                        Also, you do not have anything in the Advanced settings section, correct?

                        As to running a calibration test, consult your UPS manual or support from the manufacturer of your UPS.

                          Ok, I will test without ignorelb directive.

                          I find anything I will search tomorow
