systemd example

[KodinLanewave]

I just deployed your tool as a systemd service on Ubuntu. Since I have an example, this may be helpful for others:

config file is copied to /etc/default/renogy-bt
service file is copied to /lib/systemd/system/renogy-bt.service

Service file contents:

[Unit]
Description=Renogy Bluetooth Service
After=multi-user.target

[Service]
ExecStart=python3 /opt/renogy-bt/example.py /etc/default/renogy-bt
Restart=always
Type=simple

[Install]
WantedBy=multi-user.target

Works perfectly, logs to systemd logger under renogy-bt unit; to check logs, use journalctl -u renogy-bt
Don't forget to run systemctl daemon-reload after deploying all the files in the right places, then systemctl enable renogy-bt and systemctl start renogy-bt to enable at-boot and start the service.

Thanks for an excellent tool.

Hi I was not able to get this working with more than 1 config file, are you able to point me in the right direction.

EDIT: this solution doesn't quite work. Using the ExecStartPost means one of them times out. I have since split this into 2 service files, one for each device. However, this does still answer the original question of how to use a different config file (the battery-config.ini for example) so will leave the rest of this content here:

Here is my solution to running multiple configs from one systemd file. Appears to be working for me.

I am on a Pi 5. And running my python inside a venv/virtual environment.

The trick for me was using ExecStartPost. You can have as many of these as you want, then run one after the other following the initial ExecStart.

[Unit]
Description=Renogy Bluetooth Service
After=multi-user.target

[Service]
ExecStart=/home/admin/Renogy/venv/bin/python /home/admin/Renogy/example.py battery-config.ini
ExecStartPost=/home/admin/Renogy/venv/bin/python /home/admin/Renogy/example.py controller-config.ini
Restart=always
Type=simple

[Install]
WantedBy=multi-user.target

I am not 100% sure this is working as expected and think it may be causing time outs.

For now, I am going to split this into 2 individual services.
