What trick am I missing with rtl_433 and MQTT? (feddit.uk)

I'm hoping it's just something stupid.

I've been playing around with rtl_433 for a while, and started making decoders for various bits of kit I have. When I run things on a laptop, with the same dongle, I pick things up no problem.

Yesterday, I tried to start integrating it with HASS. I installed this 433 wrapper, and Mosquitto Broker.

The 433 wrapper seems to work, and devices are decoded in the log when I use a generic config. But when I use one that pushes to MQTT, nothing shows up in the 433 logs other than the connection to MQTT, and nothing seems to be logged on the MQTT.

I vaguely remember reading that the simple Mosquitto broker only had a limited set of devices supported, but I can't seem to find where I read that now :|

I’m a few versions behind, but I’m using the add-on without issue. A few things I would check if my setup failed:

  1. The wrapper has 2 major components. Make sure you’re running both of them.
  2. Slim down your config.
  3. You mentioned you have your own decoders. Double check the rtl_433 version that’s being used in the add-on to ensure everything is compatible.

From the /r/homeassistant lurking days, I know that some other people skip the add-on in favor of using a script or another machine that proxies the data into HA. So there are a few other options in case the add-on approach doesn’t seem to be working quite right.

The decoders I'd hashed together were not very "proper" at all, just devices with chunks of the data interpreted as values.

What I should really do is figure out how to contribute them properly to the project as actual devices, then pull that in.
