Python plugin: UPS Monitor

[manuloup]

I tried the new version of file plugin.py but I don't see anything in the log file if I check for UPS.

Not sure it is working though.

Devices look up to date, so I guess this is good.

Thanks for your help, madpatrick.

I noticed this error on my rpi running under docker...

Code: Select all

2026-06-02 10:31:43.121  Error: UPS Meterkast: (NUT_UPS) failed to load 'plugin.py'.
2026-06-02 10:31:43.258  Error: UPS Meterkast: Traceback (most recent call last):
2026-06-02 10:31:43.258  Error: UPS Meterkast:   File "/opt/domoticz/userdata/plugins/NUT_UPS/plugin.py", line 37, in <module>

2026-06-02 10:31:43.258  Error: UPS Meterkast: ModuleNotFoundError: No module named 'telnetlib'

this did work for a couple of months, is there some recent change that removed telnetlib ?

suggestions how to fix ?

For docker and installations of Python modules see https://wiki.domoticz.com/Docker#Python_Plugins

Also docker image has moved to Python 13 so perhaps the module is not compliant.

See a few post earlier

Replace: import telnetlib

I used your adjusted plugin.py and now it works.
Are you pushing that changes to the plugin developer ?

I merged the UPS Monitor sub discussion with the original discussion. Probably something went wrong while creating the question.

Guys many thanks.
I got nut running on trixi with domoticz in docker. I can confirm that updating the plugin.py with the pluging.py.txt and in stalling telnetlib3 works. Just changing the original plugin.py with "import telnetlib3 as telnetlib" didn't work. Also make sure that you have the config files set with root:nut credetials.
