@sdetweil Thanks! That worked. I added a line in mm.sh to connect to the virtual environment before launching mm.

Hi, I use Tom Hirschberger’s MMM-Temperature to display temp and humidity from an adafruit sht31d. It has a dependency of the Adafruit CircuitPython Library. I’ve upgrade my pi to Bookworm. Python now runs in a virtual environment. I can activate the virtual environment and get everything to work if I launch MM2 in the virtual environment using npm start. It doesn’t work using PM2 start MagicMirror.
I know you call call python without explicitly activating the environment but I’m not sure what changes need to be made to module.
Maybe create a systemd unit file to run the the library at startup?
Ideally, I want the same functionality back; my MM starts on boot and python works normally.
Has anyone seen this or has a fix?

Thanks!

@wishmaster270 Thank you so much for the help and troubleshooting! I wasn’t able to work on this the last few days and when I got back it looks fixed.

Thanks again.

@wishmaster270 I’m running 2.24.0 and node is v18.17.0

I wrote a script to use the SHT31-D temperature and humidity sensor from adafruit. The script works in that it correctly displays the temp and humidity. The log file however shows the following:

This is my script:

#!/usr/bin/env python3
#Install Dependencies:
#  cd ~
#  sudo pip3 install --upgrade adafruit-python-shell
#  wget https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/raspi-blinka.py
#  sudo python3 raspi-blinka.py
#  sudo pip3 install adafruit-circuitpython-sht31d
#  

import board
import adafruit_sht31d
import json

i2c = board.I2C()
h = adafruit_sht31d.SHT31D(i2c)

result = {}
try:    
    result["temperature_c"] = h.temperature
    result["humidity"] = h.relative_humidity
    result["temperature_f"] = (result["temperature_c"]*1.8) + 32
    result["error"] = False
except:
    result["temperature_c"] = 0.0
    result["humidity"] = 0.0
    result["temperature_f"] = (result["temperature_c"]*1.8) + 32
    result["error"] = True

print(json.dumps(result))

Any help would be appreciate. Python is not my native language.
