As suggested by @mccoy88f, the documentation should contain a section that explains how to automatically start keyble-mqtt on boot.

Running keyble-mqtt as a Service

To run keyble-mqtt as a service on your Raspberry Pi and ensure it starts automatically on system startup, we can create a systemd service file.

Create a new file named keyble-mqtt.service in the directory /etc/systemd/system/ with:

sudo nano /etc/systemd/system/keyble-mqtt.service

and insert the following content:

[Unit]
Description=keyble-mqtt
After=network.target

[Service]
ExecStart=/usr/bin/node /usr/lib/node_modules/keyble-mqtt/keyble-mqtt.js 01:23:45:67:89:ab 1 ca78ad9b96131414359e5e7cecfd7f9e --host 127.0.0.1
WorkingDirectory=/usr/lib/node_modules/keyble-mqtt
Restart=always

[Install]
WantedBy=multi-user.target

Make sure to replace the MAC address of the smart lock (01:23:45:67:89:ab) and the user data (1 and ca78ad9b96131414359e5e7cecfd7f9e) in the ExecStart line.

Save the file and execute the following commands to enable and start the service:

sudo systemctl enable keyble-mqtt.service
sudo systemctl start keyble-mqtt.service

keyble-mqtt will now run as a service and automatically start on system startup. To ensure that the service started correctly, you can use the following command:

sudo systemctl status keyble-mqtt.service
