Rtlamr2mqtt help

Configuration
1

Hello, I am brand new to MQTT as of yesterday. With that being said, I am attempting to get the rtlamr2mqtt add on working. I have purchased this: Nooelec NESDR Mini USB RTL-SDR & ADS-B Receiver

I have installed mqtt through mosquitto and the mqtt explorer add ons.

In the explorer I see rtlamr but it only has one topic and one message stating that it is online.

I have added rtlamr/debug topic to the explorer but I am not seeing it.

The logs of rtlamr2mqtt are here:

Can someone please tell me what I’ve done wrong?

I just set this up today and running in to the same issue as well.

3

Looks like my issue was in the config. In the configuration by default the protocol is set for scm+ but I needed just scm. I removed the + and restarted the add-on and then it published a lot more info in MQTT.

4

Any chance you could post your configuration? I tried changing mine to remove the plus but I’m still not getting anything.

Thank you! I’m starting to wonder if my receiver dongle is bad…

This was definitely helpful! Thank you again!
