RE: Esp32 failed to connect to Mosquitto MQTT Broker

ntewinkel — Fri, 28 May 2021 04:34:05 GMT

Hi Waxore,

I actually just set up a Raspberry Pi with Node-Red and Mosquitto, and set up a Wemos D1 Mini ESP8266 to connect to Mosquitto to report sensor data via MQTT.

Similar to you, I was able to test MQTT on the Raspberry Pi itself, but the ESP board could not connect.

Turns out I have my Raspberry Pi plugged into the wired ethernet in my house, and I was connecting the ESP board to the guest WiFi network. The guest network is purposely separated from my main home network for security reasons. Once I switched the ESP over to connect to my internal home network WiFi, it all works properly now.

Hoping yours is as easy a fix!

Best of luck,

-Nico

Esp32 failed to connect to Mosquitto MQTT Broker

Hello everybody I'm facing a problem in my home automation project that is based on a mosquito mqtt broker that needs to connect to some clients on the same network (node red, esp32, mqtt client app on the phone) but the problem that whenever I try to connect to the server form outside the hosting machine I fail. For example the connexion to node red that is executed on the same machine as the mqtt server is working like a charm but Any other client on the same network is blocked . I tried to create a new rule in firewall to open the 1883 port, but when I do a test using Nmap I find that the port is filtered. Also, I had some difficulties accessing the config file for mosquitto in this latest version can anyone help me please

Thank you for your response Shabaz just to share the solutions that worked for me, I was able to found a node in node red that can run a market broker called Aedes broker other than that I have searched every corner in google but I think it might be a problem with the compatibility of the latest version of mosquitto with my windows 10

Thank you again

Hi,

There must be many answers to this, depending on what you're running the server on. I really think google is your best friend here.

For example, see the answer here, which lists the steps to resolve it on 'ufw' firewall if that is what your Linux machine is running.

https://stackoverflow.com/questions/54878001/cannot-get-mosquitto-to-allow-connection-from-outside-local-network

If your server is running on a different Linux distribution with something else, then search for that version of Linux as part of your search term.

Running Snips with Matrix Creator and Raspberry Pi

aabhas — Wed, 27 Feb 2019 14:08:14 GMT

I am making voice automation project for Home Automation in Project14 ,using Snips on Matrix Creator and Raspberry Pi.Need help in interfracing them in my project using snips for voice .Wondering how to reply through voice using Snips? Idea is written below(or you can view it in comments of Project14 | Give Your Habitat a Personality Using Home Automation!),any help is welcomed.

IDEA

Home automation , who doesn't like to have their house automated , but automating our house ourself is much more exciting!

My idea is to create a home automation system for our houses using the Matrix Creator board and raspberry pi 3A+ as they would be helpful for providing the power to run home automation system with voice assistant in a very small form factor. The Matrix Creator board will help to make my project more better with voice recognition , as it has inbuit voice input and output and sensors for the required information to make our home automation based on iot.

This project would have the automation system with a voice control and it would help to control our appliances in house just with a voice command, which would be taken using the Matrix Creator board and raspberry pi 3A+ this would help us do control locally without internet using Snips and if internet is available it would use the Google assistant API of Google for voice recognition .The voice input and output would take place using the Matrix Creator board along with raspberry pi. It would help us automate our home with voice and even help us as a personal voice assistant.It control all our electric appliances using relay and this system and run it without internet also.It would allow us to control appliances using voice command and even over internet using blynk or node red and IFTTT.

This project would have a feature of detecting any sort of problem in our house like fire , gas leakage, short circuit ,etc using different sensor like ir , lpg gas sensor (mq-6) , etc and even camera and guide us during such a situation and even notify us on our phone via blynk or node red and even tell us what to through the speaker and help us accordingly .It would even contact the nearest help along with our location.

For eg if it detects gas leakage it would tell us "to check the gas pipe " and "turn off the gas mains" , and if fire is detected it would tell us how to use fire extinguisher and even turn of the electricity as required to prevent spread of fire and even notify fire station.

This project would thus automate our house using voice and even help us in problematic situations.

I would like to build this project after 20th February when my exams our over and have fun automating my house.
