What were you doing?

1. Install UPS plugin
2. Point to already configured NUT entry for local UPS
3. Plugin correctly shows UPS status
4. Print with OctoPrint
5. At some point the UPS plugin will stop updating and show stale data
6. Check with "upsc" on the command line that the UPS is still connected and sending data.
7. Sometimes (not always) opening the UPS plugin settings and saving makes the connection come back.

UPS is an APC BackUPS 1500M

What did you expect to happen?

Plugin would still update

What happened instead?

Hiya!

Recently came back to my Octoprint instance on my FFCP and noted I was having issues issuing commands. After a reboot, the Octoprint service wouldn't even start. While looking into the issue, I found my SD card completely full. Turned out it was log related and Daemon.log had been some 400+ mb. I deleted it and restarted. Everything back to normal!

Well, I thought so. Before the reboot, I was well aware of the top bar (including the UPS plugin icon). I could still see the data coming back as normal. Once I rebooted, the icon is blank with the status OFFLINE.

I confirmed NUT was acting normally using PuTTY. The data was available. But the plugin couldn't see it. I still see the configured UPS on the plugin menu drop down, so it isn't like it lost that configuration.

While checking for and update, I noticed the plugin requires Python 3+. I am still running 1.7.3, which I think operates on Python 2.7 something. I know for a fact it was working prior to the reboot I described. Am I missing something?

Hi, very nice plugin for the OctoPrint.

Thanks

I only noticed that it is very difficult to read the status popup in Darktmode:

Could this still be adjusted?

Thanks a lot FreundderNacht

Hey !

I am using a Eaton 5S 700, which is connected to via the USB port on it. Your NUT config however does seem to only be through LAN, meaning i cannot connect to the UPS in any way. Is it possible to add a option to use a USB port for the connection, besides the built-in network ? NUT should be fully capable of doing this if i remember correctly.

Thanks !

What does this PR do and why is it necessary?

Not really necessary, but it does reduce the amount of whitespace in the popover and makes it IMHO more attractive.

How was it tested? How can it be tested by the reviewer?

Tested by running in Chrome and seeing the new appearance

Screeshots

Without this fix:

With this fix

What does this PR do and why is it necessary?

Adds missing open <tr> tags to the generated table.

How was it tested? How can it be tested by the reviewer?

Ensured that the popover still looks correct with the new tags in place.

Any background context you want to provide?

This was not causing any visible issues (at least on Chrome) but could cause problems in the future

What are the relevant tickets if any?

None - this was from code review

Not sure where or why this happens yet but...

022-03-17 20:44:26,381 - octoprint.plugins.ups - ERROR - An exception occurred while getting vars info Traceback (most recent call last): File "/home/pi/.octoprint/plugins/ups/init.py", line 132, in _loop vars = self.ups.list_vars(ups=self.config['ups']) File "/home/pi/oprint/lib/python3.7/site-packages/nut2.py", line 157, in list_vars self._srv_handler.write(b"LIST VAR %s\n" % ups.encode('utf-8')) AttributeError: 'NoneType' object has no attribute 'encode'

config yaml shows ups is 'null'. Opening settings. selecting the ups again, and saving works around for a short while until it happens again.

I would like to add a request that the "pause when UPS battery gets below X%" option include another option that the pause only occurs after the current layer is completed. If my UPS drops to 50%, I'm okay if it takes another 10% to finish the layer.

Hi,

what about making use of

M118 E1 UserNotif UPS on battery and M118 E1 UserNotif UPS online

to make Telegram notifying the user when UPS switches to/from battery?

Thank you for this really nice plugin! Armando

Being new to NUT, I see there is a hole slew of commands available. I'm intrigued and want to investigate further. I would also love to be able to select from different parameters to add to the drop down.

Overall this is one of my new favorite plugins. Thanks for the contribution.

Hiya!

Want to start off by saying thanks for the upload. I have this running now and it appears to be working. I was thinking about the USB plug on the back of my UPS I am using for my 3D printer and wondering if anyone had something to integrate the two. Not sure if you read my mind, but nice job regardless.

That being said, there obviously isn't much here on how to get NUT going. I personally have never heard of it before reading it on your plugin description. Also, Linux is as powerful as it is convoluted.

When looking at the plugin config page, I though the device must be connected via Ethernet. Perhaps this is just a me thing, but it may be worth being explicit here. I'm not sure it can be set up via Ethernet (I'm new, but can't imagine that it CANT be done).

I Googled Raspberry pi NUT and stumbled across this guide:

https://community.openhab.org/t/beginners-guide-to-network-ups-tools-nut-on-a-raspberry-pi/78443

Which in turns also references:

https://melgrubb.com/2016/12/11/rphs-v2-ups/

It went OK. I did ultimately get it running. But these guides could use a little work. That being said, it would be great to have a guide here linked on the GITHUB (perhaps one that is better than these).

Anyways, thanks again for the upload. It appears to be working!
