      Actions are not taken for the device configured at ups.conf, this is only for the upsd service which setups communications with devices and can also provide access to this devices to other remote services such as a remote upsmon instance in another server.
      upsmon is the service that actually enforces action and it has its own configuration which the package only generates an entry for the UPS configured the normal way, I did add a two liner to the Advance part so that it acts when both UPS are down.

      Auto generated by the package for UPSMON

      MONITOR ups-2 1 local-monitor **** master
      SHUTDOWNCMD "/sbin/shutdown -p +0"
      POWERDOWNFLAG /etc/killpower
      

      With addition to the upsmon.conf at advance in gui

      MONITOR ups-2 1 local-monitor **** master
      SHUTDOWNCMD "/sbin/shutdown -p +0"
      POWERDOWNFLAG /etc/killpower
      
      ###ADDED LINES upsmon.conf####
      MONITOR ups-1 1 local-monitor2 **** master
      MINSUPPLIES 1
      

      Did also have to add an extra user in upsd.users as the package generates a random password everytime it saves for local-monitor

      [local-monitor2]
      password=****
      upsmon master
      

      This tells upsmon that it should monitor the 2 ups, that both UPS provide power for one PSU in the server and that it needs a minimum of one power supply to operate, so it is now fault tolerant (Will only conduct a shutdown if both UPS are down/critical power).

      The reason i add them to PFSENSE is that it depends on both UPS so I wanted a way to make sure it reflected this and didnt try anything drastic when one UPS is offline.
      It is my always on device and the last device to be shutdown and can it act as a ups provider to any other nut clients in other devices.

        MINSUPPLIES was not shown in the configuration you posted previously.

          Yes, but i also hadnt added
          MONITOR ups-1 1 local-monitor2 **** master
          to upsmon so it was not watching/monitoring the second ups.

            I have a NUT setup that used to work, but stopped working at some point (I don't know when)

            UPS type:

            pollfreq=1

            upsd.conf:

            upsd.users:

            password = blablabla
            upsmon master

              @gooberpatrol66 You haven't included the pertinent portions of your config, but best guess based on the log is that you are simply not able to connect to the UPS.

              • Be sure that you are referring to the UPS by address. Don't depend upon host name resolution for a UPS.
              • Confirm that you can actually access the UPS with the SNMP credentials specified.

              Unrelated, but a poll frequency of 1 is really overkill. The default of 5 works just fine. The lowest poll frequency recommended by NUT is 2.

                  There was a blackout in my house a few days ago. I've noticed a very weird behavior with my Eaton UPS while I was actually monitoring the shutdown process. Here are the logs:

                  The weird behavior was that after the UPS gets a shutdown command from pfsense NUT, it shuts itself down, cuts power off from the load and then turns back on right away even though there is no power from the mains yet. And then it shuts itself down again and continues this cycle until the battery gets depleted. Any ideas what's causing this?

                  Also, at 9:48:21 I see a logout from one of the remote monitors, but why is there another login event at 9:48:25 right before the shutdown event by root at 09:48:27?

                    Any ideas what's causing this?

                    The BIOS of your pfSense uses the setting "Auto power on when power comes back".
                    So, when the power comes back, it will boot again.
                    This will loop until a) the power comes back and b) the battery is charged enough so NUT decides to stay 'on'.

                    Easiest solution : don't auto boot when the power comes back. This means that the shut down is controlled, but human presence is needed to switch it on again.
                    Best solution : Have a talk with your USP. Ask it to power the oullets when a and b or ok.
                    This best solution is often not possible with a typical SoHO UPS.

                    No "help me" PM's please. Use the forum, the community will thank you.
                    Edit : and where are the logs ??

                      Perhaps I should've been more clear with my post. This cycle happens when there are no power in the mains yet. So imagine the UPS being shutdown by pfsense and then it cuts power from its outlets and then supplies power again to them (from battery). Why would the UPS do this if it was instructed to stay off until power from the mains come back?

                      I have another UPS (APC) connected to another pfsense box and when it shuts down, it stays shutdown until the mains come back. After the mains come back, pfsense (and all other NUT clients) power on and NUT knows not to initiate another shutdown event even though the thresholds are still being reached because it knows that the UPS is using mains power. This avoids the cycle you are describing.

                          That's what I understood.
                          The UPS shuts down the outlets (probably because not enough energy in the battery to sustain a valid AC voltage.

                          I might be wrong, but NUT only gets info from the UPS. It isn't sending anything to it.
                          So NUT can't tell the UPS "do this when that happens".
                          It's the UPS that sends over a status of the UPS when it is asked to do so.
                          The answer contain online/offline status, and battery charge status, and some more details.
                          Based on the UPS status, NUT does all the action work.

                          I've never seen an option like "if battery is lower then 10 % then shut down outlets" and "switch outlets back on when power is back and battery is more then 30 %".

                          Example : my UPS is called 'ups' in my pfSense.

                          I can read these parameters but the thing is : can we set (some of) them ?

                          I have another UPS (APC) connected to another pfsense box and when it shuts down, it stays shutdown until the mains come back. After the mains come back, pfsense (and all other NUT clients) power on

                          That's seems the correct behaviour to me.

                          and NUT knows not to initiate another shutdown event even though the thresholds are still being reached because it knows that the UPS is using mains power. This avoids the cycle you are describing.

                          The thing is : NUT has does nothing to here.
                          The 'mains' is up - the 'battery is charging' as these are told to NUT when it asked the UPS for info.

                          Btw : As you can see, I'm using also an APC. Not saying hey are the best, they 'work' pretty well.

                          No "help me" PM's please. Use the forum, the community will thank you.
                          Edit : and where are the logs ??

                            Perhaps I should've been more clear with my post. This cycle happens when there are no power in the mains yet.

                            That's what I understood.
                            The UPS shuts down the outlets (probably because not enough energy in the battery to sustain a valid AC voltage.

                            Are you saying that when a blackout occurs, only the remote and local (pfsense) monitors shut down and the UPS continues to supply power to the outlets until the battery gets drained?

                            I have this arguments set and I'm not sure if they make a difference in the event when all monitors are already in shutdown state:

                            override.battery.charge.warning = 80
                            override.battery.charge.low = 70
                            override.battery.runtime.low = 420

                            @kevindd992002 said in NUT package:

                            So imagine the UPS being shutdown by pfsense and then it cuts power from its outlets and then supplies power again to them (from battery). Why would the UPS do this if it was instructed to stay off until power from the mains come back?

                            I might be wrong, but NUT only gets info from the UPS. It isn't sending anything to it.
                            So NUT can't tell the UPS "do this when that happens".
                            It's the UPS that sends over a status of the UPS when it is asked to do so.
                            The answer contain online/offline status, and battery charge status, and some more details.
                            Based on the UPS status, NUT does all the action work.

                            I've never seen an option like "if battery is lower then 10 % then shut down outlets" and "switch outlets back on when power is back and battery is more then 30 %".

                            I thought it does both. @dennypage can probably confirm but I thought NUT is able to shut down the UPS outlets. What you're saying makes sense though.

                            Example : my UPS is called 'ups' in my pfSense.

                            I see. So since the UPS tells NUT it is using mains power, NUT doesn't do any of its power shutdown sequences, correct?

                              The weird behavior was that after the UPS gets a shutdown command from pfsense NUT, it shuts itself down, cuts power off from the load and then turns back on right away even though there is no power from the mains yet. And then it shuts itself down again and continues this cycle until the battery gets depleted. Any ideas what's causing this?

                              Issues such as these seem to be common with low end Eatons...

                              Research the "ondelay" parameter and these variables (if your UPS has them):

                              • battery.charge.restart
                              • battery.runtime.restart
                              • ups.delay.start
                              • ups.start.battery
                              • ups.timer.start

                              Also, you might remove any variables that may have been set such as battery.charge.low or battery.runtime.low.

                              In the end, you may not be able to fix it.

                                If I remember correctly, this is an Eaton that has 1KVA+ capacity. Are all consumer UPS Eatons considered low end?

                                Can you confirm what NUT does based on the discussion above? Does it send a command to the UPS to shut down its outlets during the shutdown process?

                                  @kevindd992002 Please see advice above.

                                  You've configured NUT to initiate shutdown when the battery gets down to 70%. On thing that comes to mind is that the Eaton may simply not support power off at such a high level.

                                  You should research the variables I gave you. Particularly those with battery in their name.

                                  If you aren't able to find a resolution that way, you will probably have to contact Eaton support for help.

                                    Yes, I did see your advice above. I just wanted to confirm the confusions we had in the discussion above where we are not sure if NUT can send commands to the UPS or just read data from it. I assume it's the former but I wantes to confirm with you. I guess my question is: when NUT initiates a shutdown, does it only send commands to the local and remote monitors or does it also send a shutdown command to the UPS?

                                    Aha! You're probably right. I did recently change the thresholds to a higher level and the UPS probably doesn't support that. If I remove the thresholds, I should also remove "ignorelb" so that it uses the default thresholds of the UPS, correct?

                                      @kevindd992002 I believe the only time you should use ignorelb is if you have a ups that incorrectly asserts low battery immediately when mains fail.

                                      Edit: This is incorrect. Using ignorelb is required in order for battery.charge.low and battery.runtime.low to be checked. Code reference here.

                                          If I remember correctly, when we were discussing this a few years ago, we came to a conclusion that ignorelb is needed for the warning/low battery thresholds override to work. Is this not the case anymore?

                                          And my pending question again: "when NUT initiates a shutdown, does it only send commands to the local and remote monitors or does it also send a shutdown command to the UPS?"

                                            @kevindd992002 said in NUT package:

                                            when NUT initiates a shutdown, does it only send commands to the local and remote monitors or does it also send a shutdown command to the UPS?

                                            NUT, the server, the one that is connected to one or multiple 'local' UPS, polls the status of the UPS. Somthing like every 5 seconds : the UPS doesn't send anything.

                                            The NUT server doesn't send to it's clients. The clients do the same thing : they poll the NUT server every xx seconds.

                                            So, NUT as a process can have a 'local UPS' or a remote, other NUT process as a souce. This means that the code for NUT as a server or as a client is the same. Only the source changes.

                                            A local UPS isn't necessary a local serial or USB device, it can even be a IP based SNMP or any other remotely access type of thing.

                                            I've read a lot of the manual yesterday ( the source code, as it is available for everybody ) and i'm pretty sure NUT server and client are only polling the 'upstream' info. This can be another NUT installation, or an UPS.
                                            ( still not 100 % convinced, though )

                                            Btw : NUT won't shut down the UPS.
                                            The UPS exposes variables in it's status record that indicate what the battery situation is ( a percentage) and a value where it goes "down". That will be the moment that the outlets go down.
                                            Up to NUT to to it's thing : shutting down locally.
                                            So, NUT itself will never 'see' that the UPS goes down. As it shuts down the device it's running ion => it shuts down itself ;)

                                            Also : NUT is not a program, it a collections of device and interface dependant drivers, server & client programs, tools etc.

                                            And again : I'm not a NUT specialist at all, but I have a couple of UPSs around me for ages now. @work and @home.

                                            No "help me" PM's please. Use the forum, the community will thank you.
