Hi Fusion Automate, what a great project! It works properly. I would like to setup a MQTT project with one ESP32 as a subscriber and another ESP32 as publisher. The broker should be a local RasPi standalone as Broker-Server creating its own WLAN without connection to the Internet via Router or Access Point. Can you give me hints how to do this? The handling of the ESP32 should be easy. But with the RasPi I have got my problems to combine the installed Mosquitto and the WLAN-Server capabilities. Do you have this setup described in one of your courses? (Please without NodeRed.) Thanks! Oli

@Fusion_Automate 7 місяців тому

Hi, Yes it is possible to do it without node-red. Actually you dont have to do anything just install mosquitto in PI and connect your pi with any wifi and same wifi you can use for esp32. You can ping me on WhatsApp or Telegram for in depth discussion or doubts.

the dht11 is working ,the problem is you have to write dht.begin in void setup when you do that everything working fine

@sufianronzi1786 13 днів тому

Thank you sir it works the other day and i was happy! But the next day i ran the program, it doesn't work.. it says connection failed just like before...I redo all like in the video again but the issue doesn't resolve... Any thoughts on this sir? Or anyone?

@Fusion_Automate 13 днів тому

I have faced the same issue, its windows problem so we have to delete all previous configuration and we have to create it again like port forwarding and firewall rules.

@sufianronzi1786 10 днів тому

@@Fusion_Automate thanks for the suggestion. I tried as per suggested and it works like magic! it looks like i need to do as per suggested every time i boot up my pc. Wondering if there's a way to not to go through the reconfiguration process each time booting up the pc. Btw, i will be using raspberry pi instead of pc. Tried already on raspberry pi and no firewall and port forwarding configuration as of now. Thank you sir and wish me luck for my fyp🙏🏼

@tatatadooooo11 Рік тому

sir. we need to create topic before run arduino code or not ? many thanks

@Fusion_Automate Рік тому

Yes, you need to create topic first in arduino code and then you have to upload code so publish and subscribe event use those topics.

I got a MQTT Server on my Pi 2 and get always rc 2 error. The MQTT Explorer trys to connect always.

@Fusion_Automate 20 днів тому

So you mean, your mqtt explorer is not able to connect with broker running inside raspberry pi ?

@Sahil-og01210 Рік тому

Sir it show failed to read from dht11 sensor although i check dht11 sensor by putting code of dhtTester it work properly

@Fusion_Automate Рік тому

Okay, then simply edit dht tester code and make integrate mqtt code in that.

how do you solve the failed to read from DHT sensor problem in serial monitor in the videp

@Fusion_Automate 8 днів тому

there was loose connection with dht11 bcs of that that error occurred.

Very good video! But I have some question about the mosquitto. The error messages are shown as below: 1711989156: Opening ipv4 listen socket on port 1883. 1711989156: Error: Only one usage of each socket address (protocol/network address/port) is normally permitted. 1711989156: Opening ipv6 listen socket on port 1883. 1711989156: Error: Only one usage of each socket address (protocol/network address/port) is normally permitted. How yo solve this problem? I google many times on this but didnt have a useful solution about this. Thank you!

@Fusion_Automate 27 днів тому

It seems like some other application is using same port 1883. So, you have to fetch which application is using same port and you have to close that application. netstat -p tcp -ano | findstr :1883 You can use above windows command to check the process id which use the port 1883.

@Fusion_Automate 26 днів тому

Can you Share it here ? So in future if some have same problem then can learn from it.

@yinyenlee109 26 днів тому

@@Fusion_Automate I just create a text file and run it as administrator with two lines, listener 1883 allow_anonymous true Then, I save it as listener.conf in the file directory of mosquitto and run the command in command prompt, mosquitto -v -c listener.conf Then the mosquitto can run already.

Also, now I am trying to import a machine learning model into node red for classification of data received through a pzem sensor, is there a way can directly import the model that I had trained into node red?

@Sahil-og01210 Рік тому

SIR, I DO THIS AS YOU SAY BUT IT SHOW MQTT CONNECTED THEN SHOW TEMPERATURE AND HUMIDITY AND AGAIN SHOW SAME THAT MQTT CONNECTED AND TEMPERATURE AND HUMIDITY ETC... BUT NOT SHOW WHEN I SUBSCRIBE TOPIC ON MYMQTT IN MY MOBILE PHONE.

there's problem in your code i need to check in your code
