[Nut-upsuser] Powercool UPS compatibility

Wonderful news Jim.

Much obliged sir!

I will reach out to the developer and make them aware.

You never know. They might even be on this mailing list.

Regards

James

Hi all,

In the comments for https://github.com/networkupstools/nut/pull/638/ adding support for "hunnox" subdriver I saw somebody report that the branch also supported their Powercool branded device. I am brushing that submission into shape to merge it, and for that matter also plan to merge the https://github.com/networkupstools/nut/pull/1008 adding an "snr" subdriver.

So hopefully a build of NUT from the master branch after these merges would let your deployment see your UPS better. That said, you may have to poke the unRAID plugin maintainer to update their package.

this is the app i am using to use NUT.

what you say about ups.conf is what i have entered and it fails to start NUT.

i've PM'ed dmacias on the unraid forums for advice but no response since the weekend when i sent it and the forum thread isn't actively responded to either.

really need dmacias to respond to enable guidance.

nut-scanner works, it picks up this:

Scanning for UPS...

[nutdev1]
driver = "nutdrv_qx"
port = "auto"
vendorid = "0001"
productid = "0000"
product = "MEC0003"
bus = "002"

but nutdrv_qx isn't a driver option so i pick "custom" and enter it in, it then appears in UPS.conf and i can start/run NUT but i do not get any readings and it says ONLINE. but if i cut the power, it doesn't change status or act on it.

since nutdrv_atcl_usb doesn't work, i feel its because its missing. if i could know how to put that driver in, it would be interesting to see what NUT did if it saw it.

i will post on the unraid forum again.

thanks for the help Jim. hopefully a solution will be found!

Subject: Re: [Nut-upsuser] Powercool UPS compatibility

I took a look at https://github.com/dmacias72/NUT-unRAID/ plugin source (not sure it is the one you have, just the first recent plugin from googling).

Unfortunately it does not seem to reference actual NUT source well, nor a plugin version, but just hoards several timestamped tarballs with binaries. By commit comments it seems that at least at some point they used the "libusb-0.1+1.0" branch which is one of our attempts to handle modern libusb-1 in NUT (note none of the attempts yet were merged to master or released "officially", but we are on it).

I can't quickly say if latest plugin builds are based on that too, or if you may have a mismatch with drivers last built for libusb-0.1 trying to use libusb-1.0 on the server. APIs differ so such mismatch might cause crashes, or just fail to start if dynamic linking detects it.

As for ups.conf, I think you should try a minimal config like:

[powercool]
driver=nutdrv_atcl_usb
port=auto

(port probably may refer to /dev/usb/... if that is persistent across boots and device plugs, but does not have to).

What also comes to mind are issues with linux user privileges - whether that account which runs NUT may connect to USB device nodes. But if nut-scanner worked, probably that is okay.

If you can edit /etc/rc.d/rc.ups, in the line which starts upsdrvctl you can add debugging with -DDDDDD which should show its attempts to find the USB device and possible griefs it may have along the way.

Note that currently, an enabled debugging mode may preclude backgrounding of the driver or other NUT daemons so not sure if you'd need to add & to the end of line so upsdrvctl is backgrounded still.

Or if you have shell access, similarly you can run
  /usr/libexec/nut/nutdrv_atcl_usb -DDDDDD -a powercool

Hope that helps,
Jim Klimov

Hi Jim

Thanks for the reply.

In NUT under unRAID there is indeed a setting to enter a driver in.

Which driver are you suggesting I try as nutdrv_qx makes NUT work, but no communication between NUT and the UPS.

Just tried nutdrv_atcl_usb.c as driver and NUT will not start.

Is there anything else I need to enter in UPS.conf to get it to work?

I believe nutdrv_atcl_usb is orthogonal to nutdrv_qx "fuji" subdriver. They both handle devices using an "ATCL" USB chip which does not have a registered vendorId/productId, but that is where similarity stops. Different UPS vendors implemented different protocols and abilities using that chip as a transport, hence two unrelated drivers.

It seems the HCL entry appeared in relation to this discussion: https://github.com/networkupstools/nut/issues/203

Looking at https://github.com/networkupstools/nut/blob/master/drivers/nutdrv_atcl_usb.c it indeed does not have many settings, just an alternate "vendor" string to match on a device which it finds with hardcoded vid:pid by looking at all USB devices.

Unfortunately I can't help with setup of unRAID bit. I'd assume there is a place to state which NUT driver you want.

I have spent the last few days researching the possibility of using a Powercool UPS with NUT under unRAID.

I have posted my findings on their forums and not had much response besides other users wanting it to work too.

https://forums.unraid.net/topic/104685-powercool-ups-compatible/

How does one utilise nutdrv_actl_usb?

https://networkupstools.org/docs/man/nutdrv_atcl_usb.html

As a means of connecting to a Powercool UPS along with nutdrv_qx?

Seeing this - https://github.com/cbedgar/nut/blob/1e9216399b890b0770a0e8b158109eaa5e61d332/data/driver.list.in

Fills me with hope that it’s feasible.

Is it feasible or am I wasting my time?
