Service failed to start

[Mr0Cake]

On reboot I get the message that the logger failed to start and exceeded the maximum retry count.
I think it is because the pms is not yet ready.
I made the following changes to the startup script:

[Unit]
Description=Enviro+ MQTT Logger
After=network.target
StartLimitIntervalSec=60
StartLimitBurst=10

[Service]
ExecStart=/usr/bin/python3 /usr/src/enviroplus-mqtt/src/main.py <arguments>
WorkingDirectory=/usr/src/enviroplus-mqtt
StandardOutput=inherit
StandardError=inherit
Restart=always
User=pi

[Install]
WantedBy=multi-user.target

Hey, I had this issue as well, then when I looked at your config saw the user. Double checked mine since I changed the user on my pi from the default. Once I made that change the service worked.

I'm having a fail to start/retry count issue as well. It looks like the computer isn't seeing paho. Paho is in there, you can see it in the directory. I'm not sure what to do from here...

Here's a chunk from the journalctl output.
