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

      I receive the notification "UPS ups battery is low" and I don't understand why.
      I changed the battery without success.
      I changed UPS (EATON ELLIPSE PRO 850) to a more powerful one without success.

      You indicated that you have 3 systems powered by the UPS, however your post does not include the notification that you are referring to, nor any information about the circumstance when the notification occurs or which system it originates from.

      Btw, unless you are trying to address a very specific problem, you should not have the items in the "Extra Arguments to driver" section. Specifically, setting "ignorelb" and specifying runtimes is almost always a mistake, although a commonly made one. Likely the only one that should be there is the shutdown delay, but that only if you need more than 20 seconds to completely a shutdown on one of the systems. My expectation is that would probably only apply if you are running the Synology as a remote client to pfSense.

          @dennypage Thanks I deleted override.battery.runtime.low and override.battery.runtime.warn and I don't receive notifications anymore. But I have another questions.

          1. When I cut power to my NUT, pfsense sends a shutdown when my NUT have :
          • 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
          1. Once my devices have been shutdown, the NUT runs for about 1 minute and displays the runtime. Then it doesn't display runtime and works about 0:02:49. I don't understand how it works.An idea ?

          Below my configuration:

          battery.charge	9

            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.

                Do you have an idea ? Sorry I'm newbie Thanks.

                  @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
