Raspberry Pi 5 DHT11 using Virtual environment

[The-Tech]

I am attempting to monitor temperature and humidity with Raspberry Pi 5 using a DHT11 sensor. My Pi is running Trixie ( 64bit) and I find that the only way to get the needed Library files and scripts to work is to now run them is using them in a Virtual environment. Using the command python3 -m venv env and then running the source env/bin/activate to activate the session. In this session I can run the needed script and get the results locally via ssh session. However, because it is running a virtual session my Zabbix agent does not seem to see the results. I am running an imported template, but I am not seeing any temperature and humidity results.

I am somewhat new to Zabbix, so I am hoping that someone else has figured out where I am going wrong.

I used the following steps, https://pimylifeup.com/raspberry-pi-install-lgpio/ and this worked well locally but I just can't figure out how to get Zabbix server to run the key for a VENV environment ( see attachment) I have several Pi's running the scripts on 32 bit bullseye fine, but they didn't need the Vir environment and I really can't keep running unsupported OS versions.

I am sure there is a simple way to get Zabbix server to run VENV python scripts but I just can't figure out what I am doing wrong.


zabbix_agentd.conf includes AllowKey=system.run[*]
visudo includes

Hello

Looks like access issues, zabbix user needs to have proper access to VENV. You can test it directly with

sudo -u zabbix /home/pi/dht/env/bin/python /home/pi/dht/dht11.py 11 4

and check if any access-related errors appear.
