Making rtl_433 autorun and output to mqtt.

create /usr/local/bin/rtl433-to-mqtt.sh hint: sudo nano

#!/bin/bash
rtl_433 -C si -F "mqtt://localhost:1883,events=rtl_433[/model][/id] -M newmodel"

make it executable sudo chmod +x /usr/local/bin/rtl433.sh

Install supervisor to autolaunch and relaunch. sudo apt install supervisor

sudo nano /etc/supervisor/supervisord.conf Append the following at the end:

[program:rtl_433]
command=/usr/local/bin/rtl433-to-mqtt.sh
autostart=true
autorestart=true
stderr_logfile=/var/log/long.err.log
stdout_logfile=/var/log/long.out.log

Restart supervisor and check to see if rtl_433 is running: sudo systemctl restart supervisor ps -Aef | grep rtl

If it is not running check the syslog for any error messages: tail -n 100 /var/log/syslog.

If you have a username/password you need to specify for mqtt the syntax looks like this for the rtl433-to-mqtt.sh file:

rtl_433 -q -F 'mqtt://BROKER_IP_ADDRESS:1883,user=USERNAME,pass=PASSWORD,retain=1,events=HomeAssistant/rtlsdr/event[/id],states=HomeAssistant/rtlsdr/state[/id]' -M newmodel

Note: This style of publishing to mqtt using rtl_433's internal mqtt publish method vs. a pipe to mosqitto_pub has a known delay.
