Beginners • Re: Cannot find RPi in systemd but finds it in ssh

When I do not include venv it fails to find the mariadb module. The mariadb module is imported before the sensor_relay module in the script:The ExecStart code is below:The systemd service status WITHOUT VENV is as follows:

When I use venv, it finds the mariadb module successfully but fails later in the sendor_relay module. The the sendor_relay module imports are as follows::The systemd service status WITH VENV is as follows:
