Autostart rtl_433 with Supervisor

Linux Home-Assistant RTL_SDR Radio

First we start by making sure supervisor is installed

sudo pip install supervisor

Make some directories for supervisor to use, and ensure your user has permissions to write to them.

sudo mkdir /var/log/supervisor
sudo chown -R <user>:<user> /var/log/supervisor
sudo mkdir /var/run/supervisor
sudo chown -R <user>:<user> /var/run/supervisor

Create the Supervisor conf file

sudo nano /usr/local/etc/supervisord.conf

Here is the configuration that I used, you will want to replace with your user name.

pidfile = /var/run/supervisor/supervisord.pid
user = <user>
identifier = supervisor
directory = /tmp
logfile = /var/log/supervisor/supervisord.log
command=/usr/local/bin/rtl_433 -F "mqtt://<mqtt_IP>,retain=0,devices=rtl_433[/model][/id]"

If everything went right you should now be running rtl_433 and serving data to your mqtt host. Let’s double check that.

ps aux | grep rtl_433

Which gives this for output:

<user>     19199  1.2  0.1  65764  9368 ?        Sl   19:49   0:00 /usr/local/bin/rtl_433 -F mqtt://<mqtt_IP> retain 0 devices rtl_433[/model][/id]

You should now be good to go.
