Hello!
As there seems to be some difficultly getting NUT to work with different UPSs I’m hopping someone with experience might enlighten me so that i can purchase a compatible unit.
My requirement are quite minimal: it should have a enough battery life so my system can shut down safely after a 30 sec delay (a typical shutdown takes about 20 sec)
Protection against voltage spikes would also be beneficial though not a strict requirement.
NAS: Measured power usage (during prime95 torture test) watt’:178.2 VA 230 x 0,82 = 188,6 amps:0.82 input/mains voltage:230 Power factor:90
They probably did, though it appears they aren’t involved with the NUT project any more as they stopped being a sponsor in 2011.
“The situation has evolved, and since 2011 Eaton does not support NUT anymore.”
“But for now, please do not consider anymore that buying Eaton products will provide you with official support from Eaton, or a better level of device support in NUT.”
Could you investigate from the “opposite” direction: set up TN as if you were installing a UPS and look at the available (and lengthy) list of models in TN’s UI which are surely supported, and choose a model which suits your price?
LarsR’ guide was very useful for me - easy to follow thankfully! This guide is what I am working through now so hopefully I can implement some of the ambitions I mention below.
As an aside: I am also very pleased to find that quite a variety of UPS metrics are available between TrueNAS reporting and netdata reporting; I need to work out how to send a weekly UPS health report via (or at least in the style of) Multi-Report and cron jobs etc.
Also: presumably when the UPS tells TN to shut down, TN could “pass the message on” and tell my desktop box to shut down (They’re both on the UPS).

Your quite right, though I’m not sure they’re still available at resellers today, and if they are it’s often a later revision like with the Eaton 3S i mentioned.
I assume the later revision probably work just as well as the older ones, but at the same time it’s been 13 years since these units where officially supported and the firmware/protocol could have changed since then.
That could be useful, though I’m not sure that being included in the driver list means that a UPS is properly supported.
For example it might be able to report that mains power is out but not the power level etc, but i never used NUT so correct me if I’m wrong.
It has not been 13 years since they have been supported! They are supported, today. I gave you the link to NUTs page on what UPS are compatible and how much so by support level, and Eaton has the highest rating, green. It’s been 13 years since they worked on the driver, but other people have worked on it since of course. I am using an Eaton 5S1500LCD as shown in my signature. That one uses the USBHID driver, just like APC and many others use, it’s the most used driver of all. I was told to use that, by, Eaton tech support.
The NUT official compatibility matrix is the one to use to help you decide. It definitely does not have all current models on it. But they also have a device dumps list with reports of glitches and basically tells you what is supported by the UPS also. That can be found here:
That and user reports here are the most reliable sources you can find. There’s thousands of model choices.
Here’s the page for the one you are considering:
The Powerwalker is listed as compatible also, but it’s driver is orange. It’s support level is the second lowest.
I hadn’t seen that library before. So does this include models that don’t appear on the drivers list, but are compatible with one of the included drivers?
It may sometimes, yes. It’s basically user reported issues/success/quirks and sometimes how to get around them like on some Cyberpower. My Eaton model I mentioned is not on the compatible matrix, but is in the dump.
There are too many UPS models to put in the matrix, so the user reported ones are very helpful. The list is invaluable for those models needing some fine tuning.
I’m no longer consider the previously mentioned Eaton model as it appears Line-Interactive UPSs offer better filtering.
Either i pick the cheaper model and save some cash, or i pick the one with a the larger battery in case I at some point might be bothered to configure my OpnSense router as a slave or perhaps even connect my AP.
Yeah, large can be better if you can put a few more devices on it. The router can be a slave.
I still take issue with:
“I meant that it was 13 years since Eaton provided official support for NUT”
They provide support for NUT today, I called them and got it. They don’t provide code for NUT any more. Nor does most any other provider on the list unless it’s just for their UPS models, proprietary.
So, you’re using 180 watts rounded in torture test. You should get 8 mins out of it from their runtime graph. Mine lasts a good hour, lol. We have a lot of shorter power outages here due to climate so that saves a lot of needless shutdowns. Obviously, the 850 should run longer and allow more stuff connected. I am sure even the smaller one can handle a router added, which is typically very low power.
