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.

import subprocess
import time
import logging

logging.basicConfig(filename='/var/log/my_script.log', level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')
def main():
    scripts = [("/opt/renogy-bt/renogybt.py",["config_3500winvchg.ini"]),( "/opt/renogy-bt/renogybt.py",["config_dcdcboost.ini"]),("/opt/renogy-bt/renogybt.py",["config_12vsmartbatt.ini"])]

    while True:
        time.sleep(10) # Optional: Add a delay between loop iterations
        for script_name, options in scripts:
            time.sleep(2)
            command = ["python3",script_name] + options
            try:
                print(f"Running {script_name}...with options  {' '.join(options)}")
                subprocess.run(command, check=True) # Use check=True to raise an error if the script fails
                print(f"Finished {script_name} {''.join(options)}.")
            except subprocess.CalledProcessError as e:
                print(f"Error running {''.join(options)}: {e}")
            except FileNotFoundError:
                print(f"Error: {script_name} {''.join(options)} not found. Ensure it's in the correct directory or path.")
        print("All scripts executed. Looping again in 10 seconds...")

if __name__ == "__main__":
    main()

This is what I tried to run multiple instances of the script in one-shot mode via systemd for multiple devices... Getting a lot of bleak errors preventing this to work reliably. Does work well when it works, getting MQTT messages from the subscription in HA
