SNMPreader - Is anyone using this successfully ?

[parkerc]

Hi

I really like the look of this SNMPreader plugin (https://github.com/ycahome/SNMPreader), to capture the energy value (kWh) from my UPS, but I can’t seem to get it to work - it just shows a list of errors in the log and not being proficient in Python - I’m at a loss on what’s wrong - (FYI - I’m running the Docker instance of Domoticz).

I couldn’t work out how to install the pysnmp4 package mentioned as it was not found and returned errors.

Code: Select all

sudo apt-get install python3-pysnmp4

perhaps due to the base linux version used on the Docker instance.? - https://hub.docker.com/r/domoticz/domoticz - so as a comment in the plugin.py said “Ficed to work with python 3 “ I was able to get the following installed.

Code: Select all

pip3 install pysnmp

running it I get the following error - which I assume is related to the version - but just want to check?

Code: Select all

The only other observation is Looking in the plugin.py - Towards the top it says

Code: Select all

import sys
sys.path.append('/usr/lib/python3/dist-packages/')
from pysnmp.entity.rfc3413.oneliner import cmdgen

Yet the errors refer to

Code: Select all

/usr/local/lib/python3.7/dist-packages

is that a potential issue ?
