Setting up psmqtt as a Service

It is possible to:

  • install the required packages into the site packages and
  • run psmqtt.py as a service upon system boot.

Current Ubuntu flavors

Make a copy of psmqtt directory e.g., to /opt/psmqtt, for use by a service:

sudo cp -r ../psmqtt /opt

Modify the included psmqtt.service:

  • specify WorkingDirectory=/opt/psmqtt
  • adjust ExecStart=/usr/bin/python3 /opt/psmqtt/psmqtt.py

Ensure that psmqtt.conf in WorkingDirectory:

  • points to your MQTT broker
  • schedule and tasks make sense

Then:

sudo cp psmqtt.service /etc/systemd/system
sudo systemctl enable psmqtt.service
sudo systemctl start psmqtt.service

Check the service status with sudo systemctl status psmqtt.

Look into syslog for potential errors:

sudo tail /var/log/syslog

In my case I noticed: ModuleNotFoundError: No module named 'recurrent'.

To resolve the problem I did sudo pip3 install -r requirements.txt to install the packages into the site-packages.

And then:

sudo systemctl restart psmqtt
