No messages to MQTT

[danesolutions]

Hi,

First of all, great software just what I was looking for!
I only have an issue with registering to my MQTT (Mosquitto) I don't have credentials set on Mosquitto.
I can't get it to work that the topic "p2000" is getting published and filled with P2000 messages.
Attached is my config.ini file.
I tried to leave the fields username/password empty or just filled in random text but I can't see the p2000 topic published.

Hope you can help me.
Kind regards

I have the same issue, also with mosquitto.
I do use a username and password but p2000 messages are not published although the debug log says it did -->

python3[15860]: 2022-06-07 22:33:00 - (PostThread) - p2000.py - DEBUG - MQTT status: Posting to 192.168.100.188:1883 topic:huis/p2000

Try to outcomment (#) line 720

It might solve your login credentials issue (not using mqtt myself)

[cyberjunky]

If this works i will do check for password/username to see if we need to call the set_pw

[cris1]

For me that did not solve the issues. My MQTT requires authentication btw.

Fill in a dummy user and password, and add and change line 717 and 722 with the data from my pull request.

@cris1 did the fix from @Dinges28 fixed your MQTT issue? (code is now updated)

[cyberjunky]

@cris1 can you try the latest code and let us know?
There was a bug which is fixed now.

I think this is the problem.
Debug says it posts to mqtt_topic

RTL-SDR-P2000Receiver-HA/p2000.py

Line 749 in cff3779

f"MQTT status: Posting to {self.mqtt_server}:{self.mqtt_port} topic:{self.mqtt_topic}"

But this is wrong because it actually posts to mqtt_topic_sensor

RTL-SDR-P2000Receiver-HA/p2000.py

Line 745 in cff3779

client.publish(self.mqtt_topic_sensor, data)

self.mqtt_topic_sensor = (
  self.mqtt_topic + "/sensor/" + self.sensorname
)

I still have a manual MQTT sensor configured in HA that expects state_topic: "p2000"
So for now I just modify the code to post to mqtt_topic again.

client.publish(self.mqtt_topic_sensor, data)
client.publish(self.mqtt_topic, data)

Maybe later it would be nice to change the format to HA MQTT Discovery...
https://www.home-assistant.io/docs/mqtt/discovery/#discovery-messages

[Dinges28]

This is done because the current script allows multiple sensors. therefore the topic_sensor is made.
But if you don't use that, be free to change it what you want it to be, no harm done... ;-)

Doing the discovery.. I tried, but no succes for me.. but if somebody else wants to try?

Hi, sorry for the delay, took me a bit to find time to test the update.
I can tell you it works for me!!

I have Mosquitto MQTT running on port 1883 and use authentication.

The mistake I made was how I subscribed to the topic. The trailing slash did the trick for me and now I see the P2000 messages in MQTT. I am not sure if this always was the issue or not..but I am glad it works.

Good job!
