Problems connecting to the mqtt broker
Deleny74 opened this issue · 4 comments
Hello,
I'm having problems connecting between my ESP and the Mosquitto Broker. My hardware is a Raspberry Pi4 with Homeassistant and an AZDelivery ESP32 Dev Kit C V4. For the instalationI used the esphome web tool. After installation I have access the board via webOS. The connection to the Truma heater is also working. I can send the two commands to heat the water. This works well. After restarting, the ESP is connected to my WiFi.
I made the other entries in the file editor according to the instructions. But, I don't get any data from the ESP. In the LOG File is an unknown IP Adress with a request but not with my IP address is 192.168.178.1.
2024-02-11 19:56:20: New connection from 172.30.32.2:55820 on port 1883.
2024-02-11 19:56:20: Client closed its connection.
I installed mqtt explorer. Here I only see the topics that I send from the home assistant.
I do not know how to continue. I also tried a different ESP module and an older version of inetbox2mqtt. always without success.
In desperation I installed a d1 mini with the image for the Victron solar controller. Here I immediately get a connection with the mqtt broker.
Does anyone else have a tip for?
Thank you.
Greetings Andreas
So after your first paragraph, you have already achieved a lot.
You can test the MQTT connection in OS mode, but you don't have a connection to the Home Assistant server there. You only get this when you change the operating mode. Which LOG files are you referring to? Obviously you are not talking about the ESP logs. You can also see logs on the ESP via a terminal connection. That would probably help.
Hi, please can you explain how I can test the MQTT connection in OS mode? I have allready changed in the Credentials the Network SSID and Wifi passcode to my Home Net. Also I have edit the Broker User & password. The Hostname ist the IP adress from my Homeassistant. I have stored the Creds and made a soft reboot (without change to run mode). I found the ESP in my NEtwork an I can connect the webOS with the new IP Adresse.
I have connect the Lin uart Adapter with the ESP and the Truma. If I press "Water Heater on" the Display from my Truma print App an after that the Water Heater works. Is that what you mean for MQTT connection test?
The Log file what I mean ist the "Protokoll" from mosquiotto broker.

here ist the LOG from my ESP32: there is one entry I was wondering about it.

Hi,
the line
INFO:mqtt_async2:Connecting to ('0.0.0.0', 1883) id=b'a842e3cd6744' clean=1
shows the problem! You have set the address of your MQTT broker incorrectly in your credentials.
What you should see are the two lines:
INFO:mqtt_async2:Connecting to ('192.168...20', 1883) id=b'782184dec058' clean=1
INFO:mqtt_async2:Connecting to ('192.168...20', 1883) id=b'782184dec058' clean=0
(I do not show the IP in full)
Only when the second line (clean=0) is showing, the registration process with the broker was correct.
Thank you for your support. I have allways writen the IP Adress from my Broker in the mask for "Hostname" in the webOS. Now I have writen the IP adress in the mask "Brokername/IP and the MQTT connection is working fine.
