apcupsd- Back UPS 650VA

JKnott

Mine is an APC BE600M1. I have the same model connected to both my pfSense firewall and my desktop system running openSUSE 15.1. The one connected to the desktop is working fine, complete with all the stats. The one connected to pfSense has a lot of missing stats.

Here's what it shows in pfSense:

Also, whether it works with a particular model would depend on when that UPS was designed, not built or purchased.

Thanks all. You’ve confirmed my suspicion that it’s an age thing. I have a Back UPS 550 that’s 10-15 years old. It works fine with apcupsd on another NetGate.

Does anyone know if this is fatal or a mere inconvenience? I do see values for both BCHARGE and TIMELEFT. Both of these, I believe, are what apcupsd key off of in a power failure when determining when it’s time to shut down. However, it looks like both of these are monitored in the event of a power failure, and if I’m not getting a value for STATUS, it may never monitor BCHARGE or TIMELEFT. Does anyone know?

I imagine from everyone’s response that there’s really nothing we can do for FreeBSD except hope the condition gets fixed.

Thanks.

I'm no expert on UPS, but my understanding is that some signal is sent by the UPS to the attached computer. I know that it's possible for one computer to send that signal to another, when there are multiple computers sharing a UPS. One computer does the monitoring and then tells the others.

Pull the power cord and find out :-)

Actually, I just did. I see the power fail was detected and some things like battery percent and minutes remaining are updating, but many other items are not displayed.

So, hopefully, the UPS will do it's job and cause a proper shut down when needed, even if those items are missing.

That's what I do. My Windows host has an APC BR800 USB that is monitored by the APCUPSD Windows port. My pfSense VM uses NUT (but using Remote APCUPSD client mode) and reads the host's UPS and subsequently relays the UPS status to my XigmaNAS which also uses NUT. But from what's been discussed, may be moot if FreeBSD doesn't read them right.

I do that on my edge firewall and a couple internal systems. I have the apcupsd package setup as a server, and the other instances use it as a net type device in apcupsd. It works fine, so long as your switch and anything else between the UPS-backed hosts are also on the same UPS.

You could use a Pi or something else Linux-y you already have on the UPS as the server and have pfSense speak to that across the network.

I would rather the FreBSD folks get up to speed on this. I shouldn't have to get more hardware to fix a problem in the software.

That's the ideal fix, but if you already happen to have things in place, then it is a fine workaround. I have several Pis already doing various tasks, I'm sure others do as well. And the Pi I use as a USB console mux is already on my UPS, for example. So I wouldn't say go out and buy a Pi, but if it's already there, why not.

@jimp LOL! I have been thinking this very thing and will probably do it. If I do, I’ll report back.
